复杂压力系统钻井是当今钻井技术领域的世界性难题，钻井过程中常常碰到多个不同压
力梯度的地层处于同一裸眼井段中，本文根据川东鄂西地区地层井漏的特点，分析了漏失原因，以双庙
1 井为例进行了提高地层承压能力技术研究，在堵漏剂配方、堵漏施工工艺等方面积累了对于海相裂缝
发育地层的堵漏经验，为以后在该地区钻井作了技术积累。

The complex pressure drilling system is a world problem in
nowaday drilling field. Several different pressure gradient stratum in
one bare hole section is always found in the drilling process.This
paper analyses the reason of loss on the basis of the stratum loss
feature in the area of east Sichuan and west Hubei and makes the
technical research of increasing the ability of stratum pressurization
by Shuang -miao 1 well as an example, which accumulates the
experience for sealing the marine split developing stratum.
