页岩油赋存状态与资源量评价方法研究进展

由低熟-成熟页岩生成并原地滞留或经极短距离二次运移至致密夹层中的页岩油,以游离态、吸附态和溶解态等形式赋存于各类微孔隙、夹层或裂缝中。页岩油资源量可采用成因法、类比法和统计模型法进行静态估算,也可根据页岩油开发过程中的动态参数进行资源动态评价;但因目前开采技术影响,页岩油中吸附态烃类难以获取,因而,页岩油中可动烃类的评价显得尤为重要。

Advances in the research on the occurrence state and resources assessment of shale oil

Shale oil was generated by the low mature-mature shale and stranded in situ or accumulated in the tight interbeds by a short distance secondary migration, which exist in all kinds of micro pores, interlayers or fissures in the form of free state, adsorption state and dissolved state. Shale oil resources can be static estimated by the genetic method, statistical model and statistical models method, and resource dynamic evaluation can be carried out according to the dynamic parameters of shale oil development process, but the shale oil in adsorption state is difficult to obtain due to the current production technique, thus it is very important for the evaluation of the movable hydrocarbon in the shale oil.
