页岩气开发现状及压裂技术综述

Development Status of Shale Gas and Related Fracturing Technologies

页岩气实质是泥岩、泥岩和页岩的夹层所产生的天然气,对页岩气的开发研究可以减少我国石油对外的依存度,缓解国内能源供应问题。主要针对国外页岩气开发现状总述,结合我国页岩气开发现状进行比对,找出相似地域,并结合美国开发页岩气压裂技术,优选出适合中国开采页岩气压裂技术。

Shale gas is a kind of nature gas produced in the interlayer of mudstone, mudstone and shale. Shale gas development in China can reduce the dependence on foreign oil, and relieve the problem of energy supply. In this paper, abroad development status of shale gas was summarized; development condition of shale gas in China was analyzed. Combined with fracturing technologies for shale gas reservoirs in the United States, some suitable fracturing technologies for Chinese shale gas reservoirs were selected.
