近年来,页岩气资源作为一种补充接替的新型非常规能源逐渐受到各国政府和石油公司的重视。页岩孔隙结构和物性特征决定页岩气的流体赋存状态、流动机制和资源量,因此如何通过有效的模型和测试方法获得能够真实反映地下岩石孔隙结构特征和孔渗性能的参数,一直是页岩气储层研究的关键问题。在总结页岩的岩石物理模型和孔隙结构模型的基础上,从定性和定量两个方面分析多种页岩物性的测试方法,并指出各种方法的适用条件和优缺点以供选择。
In recent years, shale gas resources as a supplement to replace the new unconventional energy gradually by the governments and oil companies of all countries attention. The shale pore structure and physical properties determine the fluid state, flow mechanism and resources of shale gas. Therefore, how to obtain the parameters that can truly reflect the pore structure characteristics and pore permeability of underground rocks through effective modeling and testing has been Key Issues in Shale Gas Reservoir Research. On the basis of summarizing the petrophysical model and pore structure model of shale, a variety of shale physical property testing methods are analyzed qualitatively and quantitatively, and the applicable conditions, advantages and disadvantages of each method are pointed out.
