摘要/Abstract

摘要： 借助于烃源岩生排烃模拟技术，开展了加热温度、加热速率、恒温时间、水质量分数等不同边界条件对油页岩原位转化开采影响的模拟实验。结果表明：升高转化温度、降低升温速率、延长恒温时间均有利于提高原位转化出油率和改善油品；流体压力过度升高对油品稍有改善，但出油率有所降低，且过高的流体压力（如超过开采层上覆岩层压力）会对地面工程产生破坏影响；高温地层水可能作为催化剂、反应物和溶剂参加反应，促进非共价键的断裂，提高出油率。在此基础上，提出了在干馏转化过程中加入额外的供氢物质或高温水中加入适量的水溶性催化剂提高油页岩原位转化开采出油率的方法。

Abstract: With the hydrocarbon generation and expulsion simulation technology of source rock, a series of experiments of oil shale in-situ mining simulation was made under different boundary conditions such as heating temperature, heating rate, constant heating time, and water content. The results indicated that increasing conversion temperature and decreasing heating ramp rate, prolonging constant temperature time were conducive to improve shale oil yield and its quality of oil shale in-situ mining. Fluid pressure decreased shale oil rate, but slightly improved oil quality, but excessive fluid pressure, such as over exploitation layer overburden pressure, will have a destructive effect on surface engineering. High temperature formation water may act as catalyst, reactant and solvent in the reaction, promote non covalent bond fracture, and improve oil yield. Based on the results, a new method was proposed that during the dry distillation conversion process offering additional hydrogen material, or adding soluble catalystsin to the high temperature water, may improve shale oil yield of oil shale in-situ mining.

Key words: oil shale, different boundary conditions, in-situ mining, simulation experiment, shale oil
