页岩气资源状况及开发技术综述

Summary of the distribution and the development technologies for shale gas resources

页岩气作为新兴的非常规天然气,是未来潜力巨大的清洁能源。美国等国家的页岩气开发技术日趋成熟,已经形成了从勘探、储层评价、钻井、固井、完井到压裂的一体化程序,尤其是水平井钻井技术和压裂增产技术的突破,使页岩气的产量极速增长。论文在大量调研基础上,分析了页岩气的成藏机理,综述了页岩气资源现状以及国外的开发技术,分析了国内页岩气的开发现状、面临的问题,并提出了针对性的建议,以期能够为我国页岩气的开发提供依据。

Shale gas as an emerging unconventional gas is the clean energy with great potential in the future.Shale gas exploitation technologies in United States and other countries matures gradually,which has been formed the integration process from exploration,reservoir evaluation,drilling,cementing,completion to fracturing.In particular,the breakthrough of horizontal drilling techniques and fracturing stimulation technology increases the speed of the growth of shale gas production.This paper based on a large number of research papers analyzes the accumulation mechanism of shale gas,then summarizes the status of shale gas resources and the foreign exploitation technologies,then analyzes the current situation of domestic shale gas development and the problems faced,and also makes some specific recommendations for our country to be able to provide the basis for the development of shale gas.
