Key technologies for hydraulic fracturing of normal pressure shale gas in the Zheng’an area of Guizhou

More Information
  • 贵州正安地区页岩气储层具有常压、优质页岩储层较薄、水平主应力差异大等特点,导致压裂形成复杂缝网的难度较高,进而制约了正安地区页岩气产量的提高。针对这一难点,通过对正安地区常压页岩气水平井压裂技术实践和分析,结合该地区五峰—龙马溪组页岩气储层地质特征,借鉴我国南方页岩气先进的压裂技术,形成了以水平井段内多簇密切割压裂、水平井精细化压裂设计、减阻可变粘度压裂液体系、投球暂堵转向、返排液重复利用等技术为主的压裂技术体系,并取得了良好的改造和生产效果,为正安地区页岩气的有效开发提供了强有力支撑。
