There is the desorption of methane and the vaporization of water during the stage 1 heats.Heating stratum by the stage 1 can be as far as possible Promptly carry out.Such as when the hydrocarbon containing formation is initially heated, the hydrocarbon in stratum desorbs adsorbed methane.It can be from stratum Produce the methane of desorption.If hydrocarbon containing formation further heated, the water vapor in hydrocarbon containing formation.In some hydrocarbon containing formations In, water can take up the 10-50% of the pore volume in stratum.In other stratum, water occupies the hole body of greater or lesser ratio Product.Water is usually vaporized at 160-285 DEG C under the pressure of 600-7000kPa absolute pressures in the earth formation.In some embodiments, vapour Wetability variation in the aquatic products Radix Rehmanniae layer of change and/or increased strata pressure.The wetability changes and/or increased pressure can To influence the pyrolytic reaction in stratum or other reactions.In some embodiments, the water of vaporization is produced from stratum.Other In embodiment, the water of vaporization is for the steam extraction and/or distillation in the earth formation or outside stratum.Water is discharged from stratum and Improve the storage space that the pore volume in stratum increases hydrocarbon in pore volume.
In some embodiments, stratum is further heated after stage 1 heating, so that the temperature in stratum reaches To (at least) initial pyrolysis temperature (such as temperature in temperature range lower end as shown in stage 2).Hydrocarbon in stratum may It is pyrolyzed in the stage 2.Pyrolysis temperature range changes depending on the type of hydrocarbon in stratum.Pyrolysis temperature range may include 250- 900 DEG C of temperature.Pyrolysis temperature range for producing desirable product can extend through total pyrolysis temperature range only Only a part.In some embodiments, the pyrolysis temperature range for producing desirable product may include 250-400 DEG C Temperature or 270-350 DEG C of temperature.If the temperature of hydrocarbon is slowly raised through 250-400 DEG C of temperature in stratum, when The production of pyrolysis product may be basically completed when temperature reaches 400 DEG C.The mean temperature of hydrocarbon can less than 5 DEG C/day, be less than 2 The pyrolysis temperature for producing desirable product is raised through under DEG C/day, the rate less than 1 DEG C/day or less than 0.5 DEG C/day Range.Thermal gradient can be established around heat source with multiple heat sources heating hydrocarbon containing formation, slowly to increase the temperature of hydrocarbon in stratum Pass through pyrolysis temperature range.
It may be influenced from hydrocarbon containing formation by the temperature increase rate of the pyrolysis temperature range for desirable product The quality and quantity of the formation fluid of production.Temperature is slowly raised through can for the pyrolysis temperature range of desirable product It can inhibit the flowing of long-chain molecule in stratum.Temperature is slowly raised through can for the pyrolysis temperature range of desirable product The reaction for generating undesirable product between mobilized hydrocarbons can be limited.The temperature on stratum is slowly raised through for desired Product pyrolysis temperature range can make from stratum produce high quality, high API Gravity hydrocarbon.The temperature on stratum is delayed Slow be raised through can make for the pyrolysis temperature range of desirable product as existing for hydrocarbon product taking-up in the earth formation A large amount of hydrocarbon.
In some situ heat treatment embodiments, a part of stratum is heated to desirable temperature rather than is slowly added Heat makes temperature pass through temperature range.In some embodiments, desirable temperature is 300 DEG C, 325 DEG C or 350 DEG C.It can select Other temperature are selected as desirable temperature.The superposition for carrying out the heat of self-heat power makes in the earth formation relatively quickly and efficiently Establish desirable temperature.Energy input in can adjusting from heat source to stratum by the temperature in stratum to substantially remain in institute At desired temperature.The stratum of heating part is substantially remained at desirable temperature until pyrolysis is reduced so that from stratum Producing desirable formation fluid becomes uneconomical.The ground layer segment for being subjected to pyrolysis may include by only being conducted heat by a heat source And it is brought into the region in pyrolysis temperature range.
In some embodiments, from stratum production include pyrolyzation fluid formation fluid.When formation temperature increases, The quantity of condensable hydrocarbon may be decreased in the formation fluid of production.At high temperature, stratum may output major part methane and/or Hydrogen.If by hydrocarbon containing formation heating by entire pyrolysis range, for the upper limit of pyrolysis range, the possible output in stratum is only A small amount of hydrogen.After all of the available hydrogen is depleted, the fluid-withdrawal rate of the minimum number from stratum will be generally occurred within.
After pyrolysis of hydrocarbons, a large amount of carbon and some hydrogen remain present in stratum.Retain in the earth formation apparent The carbon of ratio can be produced in the form of synthesis gas from stratum.During the stage 3 described in Fig. 1 heats, it can synthesize Gas generates.Stage 3 may include the temperature for being heated to hydrocarbon containing formation that synthesis gas to be sufficient to make to generate.Such as it can be in about 400- Synthesis gas is produced within the temperature range of about 1000 DEG C of about 1200 DEG C, about 1100 DEG C of about 500- or about 550-.When synthesis will be generated When the fluid of gas introduces stratum, the temperature of the heating part on stratum determines the composition of the synthesis gas produced in the earth formation.It can be with Generated synthesis gas is removed from stratum by producing well.
During being pyrolyzed and synthesis gas generates, the total energy content of the fluid produced from hydrocarbon containing formation can keep opposite It is constant.During being pyrolyzed under relatively low formation temperature, hence it is evident that the fluid of ratio produced can be with high energy content Condensable hydrocarbons.However at higher pyrolysis temperatures, less formation fluid may include condensable hydrocarbon.More can not Condensable formation fluids can be produced from stratum.During the generation of predominantly non-condensable formation fluids, per unit volume The energy content of the fluid produced may be reduced slightly.During synthesis gas generates, compared with the energy content of pyrolyzation fluid, The energy content for the synthesis gas of per unit volume produced is substantially reduced.However, the volume of the synthesis gas of production is in many feelings It will be obviously increased under condition, and thereby compensate for the energy content reduced.
