摘　　要：合理高效地原位开采油页岩资源对缓解常规油气资源枯竭具有重要的战略意义。鉴于目前油页岩现场原位开采的不确定性和工艺复杂性,物理模拟试验成为了研究油页岩原位开采热解及传热机制的有效手段。通过查阅大量文献发现:油页岩原位开采模拟试验装置由毫米(颗粒)尺寸向厘米、米级(现场)大型尺寸迭代升级,各种大型多功能三轴智能化试验系统已研制成功。试验研究了温度、应力和共热物质对油页岩热解的影响,分析了油气产物、孔缝结构和渗透率演化特征,形成了具有我国特色的油页岩原位开采研究体系。针对新形势下油页岩原位开采研究存在的不足,对未来的研究方向提出建议和展望,旨在完善油页岩原位开采研究体系,早日实现油页岩大规模原位开采。Reasonable and efficient in-situ exploitation of oil shale resources is of great strategic significance to alleviate the depletion of conventional oil and gas resources.In view of the uncertainty and process complexity of in-situ mining of oil shale,physical simulation test has become an effective means to study the pyrolysis and heat transfer mechanism of in-situ mining of oil shale.Through consulting a large number of literatures,it is found that the simulation test device for in-situ mining of oil shale is iteratively upgraded from millimeter(particle)size to centimeter and meter(in-site)large size,and various large-scale multi-functional triaxial intelligent test systems have been successfully developed.The effects of temperature,stress and co-heat substances on the pyrolysis of oil shale were studied experimentally.The evolution characteristics of oil and gas products,pore structure and permeability were analyzed,and a research system of in-situ mining of oil shale with Chinese characteristics was formed.In view of the shortcomings of oil shale in-situ mining research under the new situation,suggestions and prospects for future research directions are proposed to improve the research system of oil shale in-situ mining and realize large-scale in-situ mining of oil shale as soon as possible.
