威远页岩气钻井井控技术研究与应用

Research and Application of Well Control Technology in Weiyuan Shale Gas Drilling

威远页岩气施工过程中多套地层气体发育,压力高,井控风险大,易发生溢流、井喷等复杂事故。井控安全是钻井施工中的“天字”号工程,通过不断总结施工经验,强化井控技术和精细化坐岗管理等措施,实现安全生产提速。

During the construction of Weiyuan shale gas,many sets of formation gas are developed,with high pressure and high well control risk,which is prone to complex accidents such as overflow and blowout.Well control safety is the “Tianzi” project in drilling construction.By constantly summarizing construction experience,strengthening well control technology and fine on-the-job management,we can realize the acceleration of safe production.
