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.
為瞭降低海洋油氣的開髮成本,提高單井控製儲量,井眼軌跡越來越複雜.但是複雜的井眼軌跡給鑽井施工帶來瞭較大的睏難,尤其是倒劃眼起鑽,風險大大增加,本文主要討利用隨鑽測斜和隨鑽測井的數據來指導倒劃眼起鑽,從而大大降低倒劃眼起鑽的風險.

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 back-reaming.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.
