中文摘要:随着常规油气资源的不断开发,其存量资源越来越少。美国非常规油气资源的开发成功,为页岩气勘探开发奠定了技术基础。储层改造技术是决定页岩气开发成败的两大关键技术之一。而页岩气储层的脆性指数是评价页岩气储层可改造(可压裂)的关键指标。本文对国内外的页岩气储层脆性评价方法进行了广泛深入的研究,总结了岩石脆性的各种力学表征方法以及矿物成分对岩石脆性的影响,为我国页岩气储层脆性评价方法的研究提供了基础性参考资料。

Research status of shale gas reservoir brittleness evaluation method
Abstract:With the continuous development of conventional oil and gas resources, its stock resources are becoming less and less. The successful development of unconventional oil and gas resources in the United States has laid the technical foundation for shale gas exploration and development. Reservoir reconstruction technology is one of the two key technologies to determine the success or failure of shale gas development. The brittleness index of shale gas reservoirs is a key indicator for evaluating the shale gas reservoirs that can be modified (fracturable). In this paper, extensive and in-depth research on shale gas reservoir brittleness evaluation methods at home and abroad is carried out, and various mechanical characterization methods of rock brittleness and the influence of mineral composition on rock brittleness are summarized. That provides basic reference materials for the study of shale gas reservoir brittleness evaluation methods in China.
