含烃地层的性质会影响烃如何通过下层地层/上覆地层进入一个或多个生产井。 The nature of the hydrocarbon containing formation may affect how the lower stratigraphic hydrocarbon / overburden enter one or more production wells. 地层的性质包括但不限于孔隙度、渗透率、孔径分布、表面积、盐度或温度。 Properties of the formation, including but not limited to, porosity, permeability, pore size distribution, surface area, salinity or temperature. 上覆地层/下层地层的性质与烃的性质组合,例如毛细压力(静态)特性和相对渗透率(流动)特性可影响通过含烃地层的烃的流动。 Overburden / property combinations formation properties and lower hydrocarbons, such as capillary pressure (static) characteristics and relative permeability (flow) characteristics may affect the hydrocarbon containing formation by a hydrocarbon flow.

含烃地层的渗透率会随地层组成而变化。 Hydrocarbon containing formation permeability will vary with the composition of the formation. 相对渗透地层可包括夹带进如沙或碳酸盐中的重烃。 Relative permeability formations may include entrained into carbonates such as sand or heavy hydrocarbons. 此处使用的“相对渗透”指的是平均渗透率为10毫达西或更大的地层或部分地层。 As used herein, "relative permeability" refers to the average permeability of 10 millidarcy or more formations or a portion of the formation. 此处使用的“相对低渗透”指的是平均渗透率低于10毫达西的地层或部分地层。 As used herein, "relatively low permeability" refers to an average of less than 10 md permeability formations or part of the formation. 1达西等于约0.99平方微米。 1 Darcy equal about 0.99 square microns. 不可渗透部分地层的渗透率通常低于0.1毫达西。 Impermeable portion of formation permeability is generally less than 0.1 md. 在一些情况下,相对渗透地层的部分或所有烃部分主要包括重烃和/或焦油,没有支撑矿物颗粒骨架及仅仅漂浮(或不漂浮)的矿物质(例如沥青湖)。 In some cases, the relative permeability formation of part or all of a hydrocarbon portion includes heavy hydrocarbons and / or tar, no supporting mineral grain framework and only floating (or non-floating) minerals (e.g., asphalt lakes).

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。 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 containing formation fluid in the fluid mixture density is formed between the lower layer formation and the overburden. 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, the gas may be formed at the highest level, 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 fluids. 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 the formation. 通常,气体不会与含烃地层中的其它流体形成边界。 Typically, gases do not form boundaries with other hydrocarbon containing formation 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 a water layer and a lower layer in the formation. 第二边界可能形成于水层和烃层间。 Second boundary may form between the aqueous layer and in the 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 strata various boundary line combination / lower strata may occur between the hydrocarbon-bearing formation.

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。 Experience interference between the production flow and fluid-fluid interactions 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 containing formation, the different fluid layers may mix and form 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, the production of hydrocarbons may become 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。 Fluid and / or fluids and overburden / underlayer interface between the quantitative formation of (e.g., energy level) may be used to predict the flow of hydrocarbons through the hydrocarbon containing formation.

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。 Within the formation at the interface between the fluid interaction (e.g., mixing) a quantified amount of energy required to be 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 existing technologies (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, "interfacial tension", refers exists between 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 dynes / cm) may represent a fluid can not be 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 the addition of reducing the interfacial tension between the stability of the composition so obtained one immiscible fluid is dispersed 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 can be attributed 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 values (e.g., less than 1 dyne / cm) between two immiscible fluids indicates 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。 Weak between two immiscible fluids may result in a surface energy of the interaction of two fluids mixed 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。 Fluid has a low interfacial tension values due to reduced capillary forces may flow to the wellbore and then taken out from the hydrocarbon containing formation.

在含烃地层中的低盐度水可提高采自含烃地层的烃产量。 In the hydrocarbon-bearing formation in low salinity water can increase hydrocarbon production was 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 can be formed easily dispersed emulsion, which is due to the low surface tension of the low salinity water and hydrocarbons between. 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 containing formation flowable emulsion (e.g., hydrocarbons / water mixture) for 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20,000ppm的水的盐度。 "Low salinity water" as used herein, refers to a hydrocarbon containing formation with sodium chloride as the reference total dissolved solids content of less than 20,000ppm of water salinity. 在一些实施方案中,含烃地层可含有盐度小于13,000ppm的水。 In some embodiments, hydrocarbon containing formation may contain less than 13,000ppm salinity water. 在某些实施方案中,含烃地层可含有盐度为3,000-10,000ppm的水。 In certain embodiments, hydrocarbon containing formations may contain water salinity 3,000-10,000ppm. 在其它实施方案中,含烃地层中水的盐度可以为5,000-8,000ppm。 In other embodiments, hydrocarbon containing formation water salinity may 5,000-8,000ppm.

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。 Retain the viscosity and capillary action may be due to the hydrocarbon containing formation fluid in hydrocarbon wells becomes difficult in the hydrocarbon containing formation 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 forces" refers to the attraction between the fluid and at least part of the hydrocarbon containing 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 containing 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, capillary forces may be overcome by reducing the interfacial tension of the 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 forces in a hydrocarbon containing formation depends on many factors, including but not limited to the temperature of the hydrocarbon containing formation, the hydrocarbon-bearing formation water salinity and hydrocarbons in the hydrocarbon containing formation composition.

随着产率的降低,可使用附加方法使含烃地层更经济可行。 With the decrease of the yield, additional methods may be used to make a hydrocarbon containing formation more economically viable. 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 hydrocarbon-bearing formation, water (e.g. brine, steam), gases, polymers, monomers, or any combination thereof to improve the fluidity of hydrocarbons.
