四川川东气藏埋藏深、产气量大、地层压力系统复杂,裸眼中高低压力系统并存,钻井过程中井漏频繁。针对不同漏失性质,采取了不同的固井技术,提高了固井质量,满足了高压气田勘探开发的需要。
Sichuan Chuandong gas reservoirs are deep buried with large gas production and complex formation pressure system. Both high and low pressure systems coexist in the open hole, and the well leakage frequently occurs during drilling. According to different leakage properties, different cementing technologies have been adopted to improve the cementing quality and meet the exploration and development needs of high-pressure gas fields.
