页岩气开采过程中的关键技术及应用

Key Technologies and Applications in Shale Gas Extraction Process

页岩气的开采是我国近年发展起来的一项能源接替技术,与常规生储盖型油气资源的开采有着明显不同。页岩气因处于原生油气地层,储层孔洞裂隙欠发育,属自生自储型气藏。采用透气或多孔介质原理,以改变储层透气性和结构,提高渗透率,方可实现页岩气的运移与开采。现代科技的进步,为页岩气开采提供了技术支持。其关键的探、钻、试、采技术在逐步的应用中,不断向着更高效、适应性方向迈进。本文针对这些关键技术的简要论述,期望能为页岩气开采技术的进一步革新提供一点借鉴。

Shale gas extraction is an emerging energy replacement technology in China in recent years,which differs significantly from the extraction of conventional hydrocarbon resources.Shale gas,located in the original hydrocarbon strata with underdeveloped reservoir pores and fractures,belongs to the self-generating and self-storing gas reservoir type.Its extraction requires the application of principles of permeability alter-ation and structural modification in the reservoir,in order to enhance permeability and facilitate the migration and extraction of shale gas.The ad-vancement of modern technology has provided crucial support for shale gas extraction.The key exploration,drilling,testing,and production tech-nologies for shale gas development are gradually being applied towards more efficient and adaptable development.This paper provides a brief discussion on these key technologies,aiming to offer some insights for the technological innovation and application of shale gas extraction.
