[0021] 不同密度的流体(例如气、水、烃或它们的组合)可能存在于含烃地层中。 [0021] different density fluids (e.g., gas, water, hydrocarbons or combinations thereof) may be present in the hydrocarbon containing formation. 含烃地层中的流体混合物根据流体密度在下层地层和上覆地层之间形成层。 Hydrocarbon-bearing formation fluid mixture is formed according to the fluid density layer between the lower strata and overlying strata. 在含烃地层中,气体可能形成最高层,烃可能形成中间层,水可能形成底层。 In the hydrocarbon-bearing formation, may form the top of the gas, the hydrocarbon may form the intermediate layer, the water layer may be formed. 流体可在含烃底层中以任意量存在。 Hydrocarbon-containing fluid in the bottom layer can be in any amount. 地层中流体间的相互作用会在流体间产生界面或边界。 Interaction between the formation fluids will produce interface or boundary between the fluid. 流体和地层间的界面或边界可以由流体和地层间的相互作用产生。 Interface or boundary between the fluid and the formation can be produced by the interaction between the fluid and formation. 通常,气体不会与含烃地层中的其它流体形成边界。 Typically, the gas does not form a boundary in the hydrocarbon-bearing formation with other fluids. 在一个实施方案中,第一边界可能形成于水层和下层地层间。 In one embodiment, a first boundary may form between the aqueous layer and in the lower strata. 第二边界可能形成于水层和烃层间。 The second boundary layer may be formed between water and hydrocarbon layer. 第三边界可能形成于含烃地层中不同密度烃类之间。 The third boundary may form between the hydrocarbon-bearing formation containing hydrocarbons of different densities. 在一些实施方案中,带有多个边界的多种流体可能出现在含烃地层中。 In some embodiments, a plurality of fluids with multiple boundaries may be present in the hydrocarbon containing formation. 应该理解,在流体之间以及流体和上覆地层/下层地层之间的多种边界线组合可能出现在含烃地层中。 It should be understood, between the fluid and the fluid and the overlying multiple boundary line combination stratigraphic / lower strata may occur between the hydrocarbon-bearing formation.

[0022] 生产流体会干扰流体间以及流体和上覆地层/下层地层之间的相互作用。 [0022] The production of fluid can interfere with the interaction between the fluid and the fluid and the overburden / between the lower strata. 当流体从含烃地层中移走,不同的流体层会混合并形成混合流体层。 When the fluid is removed from the hydrocarbon-bearing formation in different fluid layer will mix and form a mixed fluid layers. 混合流体在流体边界可能具有不同的相互作用。 Mixed fluid in the fluid boundaries may have different interactions. 依靠混合流体在边界的相互作用,生产烃会变得困难。 Rely on the interaction boundary of the fluid mixing, production of hydrocarbons will be difficult. 流体和/或流体和上覆地层/下层地层在界面的相互作用的定量(例如能级)可用于预测通过含烃地层的烃的流动。 Fluids and / or fluids and the overburden / lower strata of quantitative interaction interface (such as level) can be used to predict the flow of hydrocarbons through the hydrocarbon-bearing formation.

[0023] 在地层内界面处流体间相互作用(例如混合)所需要的能量的定量很难测量。 [0023] within the formation at the interface between the fluid interaction (such as mixing) quantified amount of energy needed is difficult to measure. 流体间在界面处能级的定量可由现有技术(例如旋滴张力仪)测定。 At the interface between the fluid level of quantification by conventional techniques (such as spinning drop tensiometer) determination. 在界面所需相互作用能量被称作界面张力。 Interaction energy required is called the interfacial tension at the interface. 此处使用的“界面张力”,指的是存在于两种或多种具有边界的流体间的表面自由能。 As used herein, an "interfacial tension", referring to the presence in the room of two or more fluids having a boundary surface free energy. 高界面张力值(例如大于10达因/厘米)可表示一种流体不能与第二种流体混合形成流体乳液。 High interfacial tension value (e.g., greater than 10 dyne / cm) may represent a fluid not mixed with a second fluid to form a fluid emulsion. 此处使用的“乳液”,指的是通过添加降低流体间界面张力获得稳定性的组合物使一种不混溶的流体分散于第二流体中。 As used herein, "emulsion" refers to a fluid by adding to reduce the interfacial tension between the stability of the composition obtained to make an immiscible fluid dispersion in the second fluid. 流体不能混合可归因于两流体间高的表面相互作用能量。 Fluid can not mix the two fluids is attributable to the high interaction energy between the surface. 低界面张力值(例如小于1达因/厘米)表示两种不混溶流体间弱的表面相互作用。 Low interfacial tension value (e.g., less than 1 dyne / cm) is between two immiscible fluids weak surface interaction. 两种不混溶流体间弱的表面相互作用能量可导致两种流体混合形成乳液。 Between two immiscible fluids weak surface energy interaction may lead to mixing of the two fluids to form an emulsion. 具有低界面张力值的流体由于降低的毛细管力可流至井孔并随后从含烃地层中采出。 The fluid having a low interfacial tension value may be due to reduced capillary forces and subsequently flow to the well bore taken from the hydrocarbon containing formation.

[0024] 在含烃地层中的流体可以是湿的(例如含烃地层中粘附在上覆地层/下层地层上或涂附在上覆地层/下层地层上)。 [0024] In the hydrocarbon-bearing formation fluid may be wet (such as hydrocarbon-bearing formations to adhere to the overburden / lower strata or coated to overburden / lower strata on). 此处使用的“润湿性”,指的是在有其它流体的情况下,一种流体涂附或粘附在地层中固体表面上的优先性。 As used herein, "wettability" refers to the case under other fluids, a fluid coated or adhered on the priorities in the formation of a solid surface. 确定含烃地层润湿性的方法记载于Craig,Jr.的“采油工程的水驱方面”,1971年的专题集第3册,石油工程师协会。 The method of determining the wettability of hydrocarbon-bearing formation is described in Craig, Jr. "Water flooding aspect of production engineering", the 1971 thematic Episode 3, Society of Petroleum Engineers. 在一个实施方案中,在有气或水的情况下,烃可粘附于砂石上。 In one embodiment, in the presence of air or water, the hydrocarbons may adhere to the gravel. 基本被烃覆盖的上覆地层/下层地层可称作“油润湿”。 Substantially hydrocarbon covered by overburden / lower strata can be referred to as "oil wet." 上覆地层/下层地层由于在含烃地层中存在极性和/或重烃(例如浙青质)可以被“油润湿”。 Overburden / lower strata due to the presence of polar and / or heavy hydrocarbons in the hydrocarbon-bearing formation (such as Zhejiang green matter) can be "oil-wet." 地层组成(例如二氧化硅、碳酸盐或粘土)可以决定在上覆地层/下层地层表面上吸附的烃量。 Formation composition (such as silica, carbonate, or clay) may decide on the amount of hydrocarbons in the overburden / lower strata surface adsorption. 在一些实施方案中,多孔和/或可渗透地层使烃更容易润湿上覆地层/下层地层。 In some embodiments, the porous and / or permeable stratigraphic hydrocarbon easier wetting the overburden / lower strata. 基本油润湿的上覆地层/下层地层会抑制来自含烃地层的烃生产。 The basic oil wet overburden / lower strata will inhibit the production of hydrocarbons from hydrocarbon-bearing formation. 在某些实施方案中,油润湿的部分含烃地层可位于地表以下少于1000英尺处。 In certain embodiments, the oil wetted portion hydrocarbon-bearing formation may be located less than 1,000 feet below the surface. 例如油润湿地层可位于加拿大、中国、怀俄明、俄克拉何马和路易斯安娜州。 Such as oil wet ground may be located in Canada, China, Wyoming, Oklahoma and Louisiana.

[0025] 含烃地层可含有水。 [0025] hydrocarbon-bearing formation may contain water. 水可与下层地层的表面相互作用。 Water can interact with the surface of the lower strata. 此处使用的“水润湿”,指的是在上覆地层/下层地层的表面上形成水覆盖层。 As used herein, "wet water" refers to water covering layer is formed on the surface of the overburden / lower strata. 水润湿上覆地层/下层地层可通过阻止烃润湿上覆地层/下层地层而提高采自含烃地层的烃产量。 Water wet overburden / lower strata wettable overburden / lower strata by preventing hydrocarbon production and to increase the recovery of hydrocarbons from hydrocarbon-bearing formation. 在某些实施方案中,部分水润湿的含烃地层可含有少量的极性和/或重烃。 In certain embodiments, the portion of the hydrocarbon-bearing formation water wet may contain small amounts of polar and / or heavy hydrocarbons.

[0026] 在含烃地层中的水可含有矿物质(例如含有钡、钙或镁的矿物质)和无机盐(例如氯化钠、氯化钾、氯化镁)。 [0026] Water in a hydrocarbon containing formation may contain minerals (e.g., barium, calcium or magnesium minerals) and inorganic salts (such as sodium chloride, potassium chloride, magnesium chloride). 地层中水的盐度和/或水的硬度可影响含烃地层中烃的回收。 Formation water salinity and / or hardness of the water can affect the recovery of hydrocarbon-bearing formation hydrocarbons. 此处使用的“盐度”,指的是水中溶解固体的量。 As used herein, "salinity" refers to the amount of dissolved solids. 此处使用的“水的硬度”,指的是水中二价离子(例如钙、镁)的浓度。 "Water hardness" as used herein, refers to the water divalent ions (e.g., calcium, magnesium) concentration. 水的盐度和硬度可用通常的已知用方法(例如电导率、滴定法) 测量。 Water salinity and hardness are available generally known method (such as conductivity, titration method). 此处使用的“高盐度水”,指的是以氯化钠为基准总溶解固体量大于30,OOOppm的水。 "High salinity water" as used herein, are defined by reference to the total dissolved solids of sodium chloride is greater than 30, OOOppm water. 随着含烃地层中水盐度的提高,烃和水间的界面张力增大,流体可能更难生产。 As the hydrocarbon-bearing formation in the interfacial tension increase water salinity increases between hydrocarbons and water, the fluid may be more difficult to produce.

[0027] 在含烃地层中的低盐度水可提高采自含烃地层的烃产量。 [0027] The low-salinity water in the hydrocarbon-bearing formation can be increased hydrocarbon production collected from hydrocarbon-bearing formation. 烃和低盐度水可形成易分散的乳液,这是由于低盐度水和烃之间的低表面张力。 Hydrocarbons and low salinity water-dispersible form an emulsion, which is due to the low surface tension of the low salinity between water and hydrocarbons. 采自含烃地层的可流动乳液(例如烃/水混合物)的生产对生产者来说经济上更可行。 Production collected from the hydrocarbon-bearing formation flowable emulsion (such as a hydrocarbon / water mixture) to producers more economically viable. 此处使用的“低盐度水”,指的是在含烃地层中以氯化钠为基准总溶解固体量小于20,OOOppm的水的盐度。 "Low salinity water" as used herein, refers to the hydrocarbon-bearing formation with sodium chloride as the base of total dissolved solids content of less than 20, OOOppm water salinity. 在一些实施方案中,含烃地层可含有盐度小于13,OOOppm的水。 In some embodiments, hydrocarbon containing formations may contain salinity of less than 13, OOOppm water. 在某些实施方案中,含烃地层可含有盐度为3,000-10, OOOppm的水。 In certain embodiments, the hydrocarbon-bearing formation may contain salinity of 3,000-10, OOOppm water. 在其它实施方案中,含烃地层中水的盐度可以为5,000-8, OOOppm0 In other embodiments, the hydrocarbon-bearing formation water salinity can be 5,000-8, OOOppm0

[0028] 针对处理选择的含烃地层所基于的因素例如但不限于地层中含烃层的厚度、液体产量的估价、地层位置、地层的含盐量、地层的温度和含烃层的深度。 [0028] For processing selection factor is based on the hydrocarbon-bearing formation, for example, but not limited to the thickness of the formation, the valuation of liquid yield, the formation position of formation salinity, temperature and depth of formation hydrocarbon layer containing a hydrocarbon-containing layer. 最初,天然地层的压力和温度可能足以使烃流入井孔并流出地面。 Initially, natural formation pressure and temperature may be sufficient to flow into the wellbore and a hydrocarbon effluent ground. 含烃地层的温度可以为25-300°C。 Hydrocarbon-bearing formation temperature may be 25-300 ° C. 在地表以下深度少于1000英尺的含烃地层的温度可能低于50°C。 Depth below the surface temperature of less than 1,000 feet of hydrocarbon-bearing formation may be less than 50 ° C. 在一些实施方案中,在地表以下深度少于1000英尺的含烃地层的温度可能低于40°C。 In some embodiments, the depth below the surface temperature of less than 1,000 feet of hydrocarbon-bearing formation may be less than 40 ° C. 在其它实施方案中,在地层表面以下深度少于1000英尺的含烃地层的表面温度可能低于30°C。 In other embodiments, the formation depth of less than 1000 feet below the surface of the surface temperature of the hydrocarbon containing formation may be less than 30 ° C. 当从含烃地层采出烃,地层中的压力和/或温度可能会降低。 When the hydrocarbon-bearing formation producing hydrocarbons, formation pressure and / or temperature may be reduced. 各种人工提升(例如泵送、注气)和/或加热形成可用于继续从含烃地层中生产烃。 Various artificial lift (such as pumping gas injection) and / or heated to form can be used to continue the production of hydrocarbons from a hydrocarbon-bearing formation. 随着地层烃被耗尽由含烃地层生产所希望的烃会变得不经济。 With the formation hydrocarbons are exhausted from the hydrocarbon-bearing formation produce the desired hydrocarbon fatally economy.

[0029] 保留在含烃地层中的残余烃的流动可能由于烃的粘度和含烃地层孔中流体的毛细管作用而变得困难。 [0029] Reserved viscosity and capillary action may be due to hydrocarbon-bearing formation pore fluid hydrocarbons and hydrocarbon-bearing formation becomes difficult in the residual hydrocarbon flow. 此处使用的“毛细管力”,指的是在流体和至少部分含烃地层间的吸引力。 As used herein, "capillary force" refers to the attraction between the fluid and at least a portion of the hydrocarbon-bearing formation. 在一个实施方案中,毛细管力可通过提高含烃地层中的压力而被克服。 In one embodiment, capillary forces may be overcome by increasing the pressure in the hydrocarbon-bearing formation. 在其它实施方案中,毛细管力可通过降低含烃地层中流体间的界面张力而被克服。 In other embodiments, the capillary force can be overcome by reducing the interfacial tension of hydrocarbon-containing formation fluids between. 降低含烃地层中毛细管力的能力取决于多种因素,包括但不限于含烃地层的温度、含烃地层中水的盐度和含烃地层中烃的组成。 Ability to reduce the capillary force of the hydrocarbon containing formation depends on many factors, including but not limited to the temperature of the hydrocarbon-bearing formation, the hydrocarbon-bearing formation water salinity and hydrocarbons in the hydrocarbon-bearing formation the composition.

[0030] 随着产率的降低,可使用附加方法使含烃地层更经济可行。 [0030] As the lower yield, you can use additional methods to make more economically viable hydrocarbon-bearing formation. 所述方法可包括向含烃地层中加水(例如盐水、蒸汽)、气体、聚合物、单体或它们的任意组合以提高烃的流动性。 The method may include the addition of water in the hydrocarbon-bearing formation (e.g., brine, steam), gases, polymers, monomers, or any combination thereof to improve the fluidity of hydrocarbons.

[0032] 采自含烃地层的产量可通过使用聚合物和/或单体处理含烃地层使烃流入一口或多口生产井而提高。 [0032] Yield collected from the hydrocarbon containing formation may flow into the hydrocarbon-bearing formation bite or a hydrocarbon producing wells by using a polymer and / or monomer improves handling. 聚合物和/或单体可降低含烃地层孔中水相的流动性。 Polymer and / or monomer may reduce the hydrocarbon-bearing formation of the hole mobility of the water phase. 水流动性的降低可使烃更容易通过含烃地层。 Water fluidity of hydrocarbon can more readily reduced by the hydrocarbon containing formation. 聚合物包括但不限于聚丙烯酰胺、部分水解聚丙烯酰胺、 聚丙烯酸酯、烯属共聚物、生物聚合物、羧甲基纤维素、聚乙烯醇、聚苯乙烯磺酸酯、聚乙烯吡咯烷酮、AMPS (2-丙烯酰胺-2-甲基丙烷磺酸酯)或它们的混合物。 Polymers include, but are not limited to polyacrylamide, partially hydrolyzed polyacrylamide, polyacrylates, ethylenic copolymers, biopolymers, carboxymethylcellulose, polyvinyl alcohol, polystyrene sulfonate, polyvinyl pyrrolidone, AMPS (2- acrylamido-2-methyl-propane sulfonate), or mixtures thereof. 烯属共聚物的例子包括丙烯酸和丙烯酰胺的共聚物、丙烯酸和十二烷基丙烯酸酯的共聚物、十二烷基丙烯酸酯和丙烯酰胺的共聚物。 Examples include olefinic copolymers of acrylic acid and acrylamide, acrylic acid and dodecyl acrylate, dodecyl acrylate and acrylamide. 生物聚合物的例子包括黄原胶和瓜耳豆胶。 Examples of biopolymers include xanthan gum and guar gum. 在一些实施方案中,聚合物可在含烃地层中原位交联。 In some embodiments, the polymer can be hydrocarbon-bearing formation in situ crosslinking. 在其它实施方案中,聚合物可在含烃地层中原位生成。 In other embodiments, the polymer can be formed in situ in the hydrocarbon-bearing formation. 原油回收使用的聚合物及聚合物的制备记载于=Zhang等人的US 6,427,268,发明名称为“疏水性联合聚合物的制备方法、使用方法及组合物”;Wang的US 6,439,308,发明名称为“泡沫驱法” ;Smith的US 5,654,261,发明名称为“用于油回收的渗透改性组合物” ;Surles等人的US 5,284,206,发明名称为“地层处理”;Surles等人的US 5,199,490,发明名称为“地层处理”和Morgenthaler等人的US 5,103,909,发明名称为“强化油回收中的曲线控制”,所有这些作为参考引入本申请中。 The preparation of polymers and polymer used oil recovery described in = Zhang et al.
