In some cases, some or all hydrocarbon parts of permeable formation can mainly be heavy hydrocarbon and/or tar relatively, and do not support the ore particle framework and floating (or not having) mineral matter (for example pitch lake) is only arranged.
Some type that contains the heavy hydrocarbon stratum also can be but be not limited to natural mineral wax or natural asphalt." natural mineral wax " appears in the mineral ore that is essentially tubulose usually, and it can be wide several meters, long number kilometer and dark hundreds of rice." natural asphalt " comprises the solid hydrocarbons of aromatic composition, and appears at usually in the big mineral ore.For example natural mineral wax and natural asphalt can comprise that fusion forms liquid hydrocarbon and/or solution mining hydrocarbon from the stratum to recovery of hydrocarbons from the formation crude position.
" upgrading " is meant the quality that improves hydrocarbon.For example upgrading of heavy hydrocarbons can make the API Gravity of heavy hydrocarbon improve.
Hydrocarbon in can the treated in various ways stratum is to make many different products.In some embodiments, the hydrocarbon in the stratum is handled stage by stage.Fig. 1 has described the explanation to the stage of heating hydrocarbon containing formation.Fig. 1 also described from the formation fluid on stratum in the productive rate (" Y ") (y axle) of barrels of oil equivalent/ton in ℃ the example of temperature (" T ") (x axle) on heating stratum.
The desorb of methane and the vaporization of water appearred between 1 period of heating of stage.Can as far as possible promptly carry out through stage 1 heating stratum.For example when at first hydrocarbon containing formation being heated, the adsorbed methane of hydrocarbon desorb in the stratum.Methane that can production desorb from the stratum.If hydrocarbon containing formation is further heated, the then water vapor in the hydrocarbon containing formation.In some hydrocarbon containing formations, water can occupy the 10-50% of the pore volume in the stratum.In other stratum, water occupies the pore volume of greater or lesser ratio.Water is vaporized under the pressure of 600-7000kPa absolute pressure at 160-285 ℃ in the stratum usually.In some embodiments, the strata pressure of variation of the wetability in the water generates stratum of vaporization and/or increase.The pressure that this wetability changes and/or increases can influence pyrolytic reaction or other reaction in the stratum.In some embodiments, from the stratum, produce the water of vaporization.In other embodiments, the water of vaporization is used on the stratum or the drawing gas and/or distill of stratum outside.Water is discharged from the stratum and the pore volume that improves in the stratum has increased the storage area of hydrocarbon in the pore volume.
In some embodiments, after stage 1 heating, the stratum is further heated, so that the temperature in the stratum reaches (at least) the initial pyrolysis temperature temperature of the temperature range lower end shown in the stage 2 (for example).Hydrocarbon in the stratum maybe the stage 2 by pyrolysis.Pyrolysis temperature range depends on the kind of hydrocarbon in the stratum and changes.Pyrolysis temperature range can comprise 250-900 ℃ temperature.The pyrolysis temperature range that is used to produce desirable product can extend through the only part of total pyro lysis temperature temperature range.In some embodiments, the pyrolysis temperature range that is used to produce desirable product can comprise 250-400 ℃ temperature or 270-350 ℃ temperature.If the temperature of hydrocarbon slowly raises and passes through 250-400 ℃ temperature in the stratum, then the production of pyrolysis product possibly accomplished basically when temperature reaches 400 ℃.The average temperature of hydrocarbon can less than 5 ℃/day, less than 2 ℃/day, less than 1 ℃/day or less than 0.5 ℃/day speed under raise through being used to produce the pyrolysis temperature range of desirable product.Can around thermal source, set up thermal gradient with a plurality of thermal source heating hydrocarbon containing formations, pass through pyrolysis temperature range with the temperature of hydrocarbon in the slow rising stratum.
The temperature increase rate of the pyrolysis temperature range through being used for desirable product possibly influence the quality and the quantity of the formation fluid of producing from hydrocarbon containing formation.The slow rising of temperature possibly suppressed flowing of stratum long-chain molecule through the pyrolysis temperature range that is used for desirable product.The slow rising of temperature possibly is limited in the reaction that produces undesirable product between the mobile hydrocarbon through the pyrolysis temperature range that is used for desirable product.Can be with the pyrolysis temperature range that the temperature on stratum slowly raises through being used for desirable product so that produce the hydrocarbon of high-quality, high API Gravity from the stratum.Can be so that a large amount of hydrocarbon that taking-up exists on the stratum as hydrocarbon product with slow rising of temperature on stratum through the pyrolysis temperature range that is used for desirable product.
In some situ heat treatment embodiments, with a part of stratum be heated to temperature desired rather than slowly heating make temperature pass through temperature range.In some embodiments, temperature desired is 300 ℃, 325 ℃ or 350 ℃.The temperature that can select other is as temperature desired.Make from the stack of the heat of thermal source and in the stratum, to set up temperature desired relatively rapidly and effectively.Energy input in can regulating from the thermal source to the stratum is to remain on the temperature in the stratum under the temperature desired basically.The stratum of heating part remained under the temperature desired to reduce up to pyrolysis basically make that from the stratum, producing desirable formation fluid becomes uneconomical.The ground layer segment that stands pyrolysis can comprise through only being brought into the zone in the pyrolysis temperature range by a thermal source heat transfer.
In some embodiments, from the stratum, produce the formation fluid that comprises pyrolyzation fluid.When the stratum temperature increased, the quantity of condensable hydrocarbon possibly reduce in the formation fluid of production.At high temperature, the stratum maybe most of methane of output and/or hydrogen.If through whole pyrolysis range, then for the upper limit of pyrolysis range, the stratum maybe the only a spot of hydrogen of output with the hydrocarbon containing formation heating.After all obtainable hydrogen exhaustions, with the fluid-withdrawal rate that occurs usually from the minimum number on stratum.
After the hydrocarbon pyrolysis, a large amount of carbon possibly still be present in the stratum with some hydrogen.Being retained in the form that the carbon of the obvious ratio in the stratum can synthesis gas produces from the stratum.Between 3 periods of heating of stage of in Fig. 1, describing, synthesis gas can occur and generate.Stage 3 can comprise hydrocarbon containing formation is heated to the temperature that is enough to make that synthesis gas generates.For example can in about 1200 ℃ of about 400-, the about 1100 ℃ of temperature ranges that perhaps about 550-is about 1000 ℃ of about 500-, produce synthesis gas.When the fluid that will produce synthesis gas is introduced the stratum, the composition of the synthesis gas that the temperature of the heating part on stratum has determined in the stratum, to produce.Can from the stratum, shift out the synthesis gas that is produced through producing well.
During pyrolysis and synthesis gas generation, it is constant relatively that the total energy content of the fluid of from hydrocarbon containing formation, producing can keep.During pyrolysis under the low relatively formation temperature, obviously the fluid of being produced of ratio can be the condensable hydrocarbons with high energy content.Yet under higher pyrolysis temperature, less formation fluid can comprise condensable hydrocarbon.More can not condensable formation fluids can from the stratum, produce.Be mainly can not the generation of condensable formation fluids during, the energy content of the fluid of being produced of per unit volume possibly reduce a little.During synthesis gas produces, to compare with the energy content of pyrolyzation fluid, the energy content of the synthesis gas of being produced of per unit volume obviously reduces.Yet the volume of the synthesis gas of production will obviously increase in many cases, remedy the energy content of reduction thus.
