摘要
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。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。
Drilling with complex pressure system is a worldwide difficult problem. Several different pressure gradient stra- turns exist in the same bare hole section, which is very common in the drilling process. This paper analyses the reasons of loss according to stratum features in the area of Eastern Sichuan and Western Hubei and makes the technical research on in- creasing the ability of stratum pressurization with case of Well-1 of Shuangmiao, accumulates the experience for sealing in marine fissure-developing stratum.
