摘要
狮子沟是青海油田的重点勘探开发区块,但该地区存在膏盐层厚、裂缝发育,地层倾角大等特点,导致钻井难度较大。分析对比了狮41井设计与实钻情况及该井钻井时效,对该井钻井托压问题的解决方法做了重点讨论,得出的结论为该区今后的钻井工作提供了经验借鉴。
Shizigou is an important exploration and development block of Qinghai oilfield, but the region has the characteristics of thick gypsum salt layer, developed cracks, large dip angle, which result in the drilling difficulty. The designed well structure of Shi 41 well was compared with the actual well structure, the drilling efficiency of the well was analyzed, and the solution to the problem of drilling holding pressure in the well is discussed. The conclusions obtained in this paper can provide reference for the future well drilling in the block.
