摘要

S106 井是塔里木盆地沙雅隆起塔里木乡构造上的一口探井,该地区盐膏层埋藏深,厚度大,受高温高压等因素的影响,钻井矛盾较为突出。通过对S106 井盐膏层(5 142～5 402 m) 钻井过程中出现的井漏、掉钻具、侧钻等复杂情况的分析,总结了该地区盐膏层钻井难点的解决方法,探讨了该地区盐膏层的钻井技术。

Abstract

S106 well is an exploration well of Talimuxiang

structure in Shaya uplift in Talimu basin ,where salt-gypsum

bed is thick and buried deeply. In the influence of high

temperature and high pressure ,many complex problems are

happened in the drilling of salt-gypsum bed in S106 well ,

such as lost circulation ,lost drilling tool ,sidetrack and so on .

Through analyzing the above problems ,the drilling technique

of salt-gypsum bed in the area is discussed ,and the drilling

difficulty is solved.
