Oil transfer in shale formation is different from conventional reservoirs due to the abundant nanopores and organic matters. The various storage states of shale oil make the available models not valid. A model considering fluids desorption and phase behavior, which are the major differences from flow in other types of reservoirs, is important for shale oil reservoir development. Based on experimental studies and theoretical analysis, a chemical reaction model is introduced coupling Darcy flow in the pores, fluids desorption in organic matters and on pore surfaces, and phase behavior of confined fluids. The relation between the concentrations of reactants and the physical properties of shale is established to make the chemical reaction model extend to shale oil simulation. Then the model is verified by experimental results and the influences of different mechanisms on oil production are systematically analyzed. The results show that the organic matter retards the transfer of sorption fluids and the existence of solution gas significantly enhances the oil-displacement efficiency. A higher TOC and a larger pressure difference make the ultimate production of dead oil higher. An optimal pressure difference and a reasonable solution gas-oil ratio could help to improve the ultimate production for solution gas drive. This work provides a more convenient approach to imitate the flow characteristics of shale oil, and the result agrees better with the field data.

由于丰富的纳米孔和有机质，页岩形成中的油传输不同于常规油藏。页岩油的各种存储状态使可用模型无效。考虑页岩油储层开发的重要模型是考虑流体解吸和相行为的模型，这是与其他类型油藏的流量的主要区别。基于实验研究和理论分析，建立了一个化学反应模型，该模型耦合了孔中的达西流动，有机物和孔表面中的流体解吸以及密闭流体的相行为。建立了反应物浓度与页岩物理性质之间的关系，使化学反应模型扩展到页岩油模拟中。然后通过实验结果验证了模型，并系统分析了不同机理对产油量的影响。结果表明，有机物阻碍了吸附液的转移，溶液气的存在显着提高了驱油效率。更高的总有机碳（TOC）和更大的压差使死油的最终产量更高。最佳压力差和合理的溶液气油比可以帮助提高溶液气驱的最终产量。这项工作为模拟页岩油的流动特性提供了一种更方便的方法，其结果与现场数据更加吻合。结果表明，有机物阻碍了吸附液的转移，溶液气的存在显着提高了驱油效率。更高的总有机碳（TOC）和更大的压差使死油的最终产量更高。最佳压力差和合理的溶液气油比可以帮助提高溶液气驱的最终产量。这项工作为模拟页岩油的流动特性提供了一种更方便的方法，其结果与现场数据更加吻合。结果表明，有机物阻碍了吸附液的转移，溶液气的存在显着提高了驱油效率。更高的总有机碳（TOC）和更大的压差使死油的最终产量更高。最佳压力差和合理的溶液气油比可以帮助提高溶液气驱的最终产量。这项工作为模拟页岩油的流动特性提供了一种更方便的方法，其结果与现场数据更加吻合。
