| 摘 要： | AT16井是位于沙雅隆起阿克库勒凸起东南斜坡带的一口探井,该井在石炭系巴楚组钻遇长达261 m(5 057～5 318 m井段)的盐膏层段.由于该井盐上地层为长裸眼段,地层压力系数低,易漏,因此钻进至井深5000m时,应使用承压堵漏工艺技术对井身5000m以上的裸眼段进行先期堵漏,使地层承压能力提高,为盐膏层顺利钻进提供保障.本文对此次承压堵漏进行了分析,提出了自己的一些认识和建议.

| Abstract: | AT16 well is a prospected well in the bossy southeast ramp region of Shaya Akekule uplift.A 261m long(5057~5318m) carbonate zone is encountered while drilling a long open hole at Bachu area in carboniferous system.Formation over carbonate zone of AT16 Well is an open hole section,and its reservoir pressure coefficient is low,it’s easy to lost circulation,so mud loss control under pressure should be used to plug open-hole formation while drilling well depth is over 5 000 m in order to improve formation pressure ability and supply support for smoothly drilling in carbonate zone.In this paper,the technology process of mud loss control under pressures was analyzed,and some suggestions were put forward. |
