在第1阶段加热期间发生甲烷的解吸和水的蒸发。 Evaporation of methane desorption and water occurs during stage 1 heating. 通过第1阶段可以尽快进行岩层的加热。 By Phase 1 can be heated rock as soon as possible. 例如,当含烃岩层最初受热时,岩层中的烃将吸附的甲烷解吸。 For example, when initially heated hydrocarbon-containing formation, the formation of methane desorption of the adsorbed hydrocarbons. 岩层可以产生解吸的甲烷。 Rock can produce methane desorption. 如果含烃岩层进一步受热,则含烃岩层中的水受到蒸发。 If further heated hydrocarbon-containing formations, the hydrocarbon-bearing formations of water by evaporation. 在某些含烃岩层中,水可能占到岩层中孔隙体积的10%至50%。 In some hydrocarbon containing formations, water may account for 10-50% of the pore volume of the rock. 在其它岩层中,水占孔隙体积的更大或更小的部分。 In other formations, water accounts for a greater or smaller portion of the pore volume. 水通常在岩层中在160℃至285℃之间600kPa绝对压力至7000kPa绝对压力下蒸发。 Water is usually in the formation between 160 ℃ to 285 ℃ 600kPa to 7000kPa absolute pressure absolute pressure evaporation. 在某些实施例中,蒸发的水在岩层中产生湿度变化和/或增大的岩层压力。 In certain embodiments, the evaporation of water produced changes in humidity and / or increased formation pressure in the formation. 湿度变化和/或增大的压力可以影响岩层中的热解反应或其他反应。 Changes in humidity and / or increased pressure may affect pyrolysis reactions or other reactions in the formation. 在某些实施例中,岩层产生蒸发的水。 In some embodiments, generating the formation of water evaporation. 在其它实施例中,蒸发的水用于岩层中或岩层外的抽汽和/或蒸汽蒸馏。 In other embodiments, the evaporation of water is used for steam extraction and / or steam distillation or rock formations outside. 从岩层中去除水和增大岩层中孔隙体积增大了孔隙体积中烃的存储空间。 Removal of water and increase the formation pore volume increases the pore volume of the hydrocarbons from the formation of the storage space.

在某些实施例中,在步骤1加热之后,岩层进一步受热,从而岩层中的温度达到(至少)初始热解温度(如步骤2所示温度范围低端处的温度)。 In certain embodiments, after the heating step, the formation is heated further, so that the temperature of the formation reaches (at least) an initial pyrolysis temperature (temperature at the low end of the temperature range as shown in step 2). 岩层中的烃可以通过步骤2热解。 Hydrocarbon formation through the pyrolysis step 2. 热解温度范围根据岩层中烃的类型而改变。 Pyrolysis temperature range according to the type of hydrocarbon formation and change. 该热解温度范围可以包括250℃至900℃之间的温度。 The pyrolysis temperature range may include temperatures between 250 ℃ to 900 ℃ the. 用于产生期望产品的热解温度范围可以只延伸通过总热解温度范围的一部分。 Pyrolysis temperature range for producing desired products may extend only a portion of the total pyrolysis temperature range by heat. 在某些实施例中,用于产生期望产品的热解温度范围可以包括250℃至400℃之间的温度或270℃至350℃之间的温度。 In certain embodiments, for generating the desired products pyrolysis temperature range may include temperatures between 250 ℃ to 400 ℃ or 270 ℃ to a temperature between 350 ℃. 如果岩层中烃的温度通过250℃至400℃的温度范围缓慢升高,则当温度达到400℃时热解产品的产生可以基本完成。 If the temperature of hydrocarbons in the formation through the temperature range of 250 ℃ to 400 ℃ slowly rises, when the temperature reaches 400 ℃ produce pyrolysis products may be substantially complete. 用数个热源加热含烃岩层可以在热源周围建立热梯度,该热梯度缓慢升高岩层中烃的温度使其通过热解温度范围。 A plurality of heat source with the hydrocarbon containing formation may establish thermal gradients around the heat source, the thermal gradient increases slowly to make the temperature of hydrocarbons in the formation through the pyrolysis temperature range.

在某些原地转换实施例中,岩层的一部分加热到期望温度,而不是缓慢加热温度使其通过温度范围。 In some in situ conversion embodiments, a portion of the formation is heated to a desired temperature instead of slowly heating the temperature through a temperature range it. 在某些实施例中,期望温度是300℃、325℃或350℃。 In certain embodiments, the desired temperature is 300 ℃, 325 ℃ or 350 ℃. 也可以选择其它温度作为期望温度。 You can also select other temperature as the desired temperature. 来自热源的热量的叠加允许在岩层中较快和较有效地建立期望温度。 Superposition of heat from a heat source to allow faster and more effective to establish the desired temperature in the formation. 可以调节从热源输入到岩层中的能量,以将岩层中的温度基本保持在期望的温度。 You can adjust the heat input into the formation energy to the formation of the temperature remained at a desired temperature. 岩层的受热部分基本保持在期望温度,直到热解衰退为止,从而来自岩层的期望岩层流体的产品变得不经济。 Heated portion of the formation is maintained substantially at the desired temperature until pyrolysis until the recession, whereby the desired product formation fluid from the formation becomes uneconomical. 进行热解的岩层的部分可以包括通过只从一个热源传递的热量达到热解温度范围的区域。 Be part of rock pyrolysis may include only reached by pyrolysis temperature range from a heat source heat transfer area.

在某些实施例中,岩层产生包括热解流体的岩层流体。 In certain embodiments, the formation produced include pyrolysis fluid formation fluid. 随着岩层的温度升高,所产生的岩层流体中可冷凝烃的数量可能降低。 With formation temperature, formation fluid produced condensable hydrocarbons may reduce the number. 在高温下,岩层可能主要产生甲烷和/或氢。 At high temperatures, the formation may produce mainly methane and / or hydrogen. 如果含烃岩层加热穿过整个热解范围,则岩层可能朝热解范围的上限只产生少量氢。 If the hydrocarbon containing formation is heated through the entire pyrolysis range, the formation may be towards the upper limit of the pyrolysis range produced only a small amount of hydrogen. 在大多数现有的氢用尽之后,将通常发生岩层产生最少量的流体产品。 After most of the existing hydrogen is exhausted, it will usually produce the least amount of rock occur fluid products.

在烃的热解之后,在岩层中可能仍然存在大量的碳和一些氢。 After the hot hydrocarbon solution, it may still exist a number of large amounts of carbon and hydrogen in the formation. 含在岩层中的碳的主要部分可以从岩层生产成合成气的形式。 The main part of the carbon contained in the rock formations can be produced from the formation to form synthesis gas. 合成气的产生可以发生在附图1中所示第3阶段加热期间。 Generating synthesis gas may take place during stage 3 heating 1 shown in the drawings. 第3阶段可以包括将含烃岩层加热到足以允许合成气产生的温度。 Stage 3 may include a hydrocarbon containing formation is heated to a temperature sufficient to allow synthesis gas produced. 例如,合成气可以在从400℃到1200℃、500℃到1100℃,或550℃到1000℃的温度范围中产生。 For example, synthesis gas can be from 400 ℃ to 1200 ℃, produced at 500 ℃ to 1100 ℃, or 550 ℃ to 1000 ℃ temperature range. 合成气产生流体导入岩层时岩层的受热部分的温度决定岩层中所产生的合成气的成分。 Synthesis gas produced fluid is introduced into the formation temperature of the heated portion of the rock formations decision ingredients produced syngas. 所产生的合成气体可以通过一个或多个生产井从岩层去除。 The synthesis gas produced may be removed from the formation through one or more production wells.
