The Development Status and Policy Suggestions for Shale Gas Fracturing Technologies in China

由于页岩极低的孔隙率与渗透率,页岩气压裂技术是现代页岩气开采及增产过程中的关键技术之一.本文通过梳理总结重复压裂、同步压裂、水平分段压裂及泡沫压裂技术的特征及应用,针对我国页岩气压裂技术的发展现状和存在问题提出:深化页岩气压裂技术理论基础研究、建立完善页岩气压裂相关法律法规,出台针对页岩气开采行业的财政及金融支持等政策建议.

Due to the extremely low permeability and porosity of shale,the exploitation of shale gas is generally performed under high fluid resistance.In order to overcome this problem and increase the overall producing efficiency,fracturing is now one of the most crucial steps during modem shale gas extraction process.This paper elaborates the urgency of promoting the development of natural gas industry,reviews the current research states of shale gas fracturing technology,analyzes the technical characteristics of re-fracturing,simultaneous fracturing,horizontal well multi-staged fracturing and foam fracturing technology along with domestic and foreign shale gas well fracturing cases,and provides future development suggestions based on current existing problems in China as:Deepening the theoretical research of shale gas fracturing technology,especially in the foam fracturing area;Establishing relevant laws and regulations while lowering the barriers to entry;Introducing government-based financial resources and supporting policies for the shale gas industry.
