利用随钻测井资料指导倒滑眼作业

Using the LWD data to indicate the back-reaming operation

为了降低海洋油气的开发成本,提高单井控制储量,井眼轨迹越来越复杂。但是复杂的井眼轨迹给钻井施工带来了较大的困难,尤其是倒划眼起钻,风险大大增加,本文主要讨利用随钻测斜和随钻测井的数据来指导倒划眼起钻,从而大大降低倒划眼起钻的风险。

The well track is becoming increasingly complex to reduce off-shore oil &gas developing costs and improve control reserves of single wells.However,the complicated well track brings much difficulties to the drilling operation,especially to the backreaming.The MWD(measure while drilling)and LWD(log while drilling)data are used in this paper to indicate the back-reaming operation,so as to reduce the risk of the operation.
