- 摘要:
页岩气地质评价中的总有机碳、热成熟度及有机质类型、含气量、孔隙度、矿物组成及裂缝发育程度等诸多参数需要通过实验测试来获取，而常规油气的实验测试方法并不完全适用于页岩气。调查了页岩气地质评价实验测试技术现状，将其划分为含气性分析、地球化学分析、岩石物性分析、岩石学分析、岩石力学分析等五大类，论述了页岩气实验测试技术的研究进展和参考测试标准。研究表明，页岩气实验测试技术将向微观发展，从纳米级甚至原子级来研究泥页岩中的孔隙结构及流体赋存状态。但中国页岩气实验目前尚处于探索研究阶段，因此亟需建立适合中国地质条件的页岩气实验技术体系。
The key control factors of shale gas geological evaluation include total organic carbon (TOC), thermal maturity, organic matter type, gas content, degree of porosity, mineral composition and fracture development degree, etc. These parameters can be obtained through testing technology, but conventional experiment testing methods are not suitable for shale gas. Investigated is the present situation of the shale gas geology evaluation experiment testing technology and the technology is divided into such five type as gas content analysis, geochemical analysis, petrophysical analysis, petrological analysis and rock mechanics analysis and introduced are research progress and reference test standard of shale gas testing technology. Research results show that shale gas testing technology is developing towards the micro, but domestic shale gas testing technology is still in the stage of study. Therefore, it is badly in need of establishing shale gas experiment test technology system for geological conditions in China.
