摘要
从永42区块的实际情况出发,通过在三开定向井段优选PDC钻头和螺杆钻具,同时优选钻井参数、钻具组合和钻井液体系,使平均机械钻速有了较大幅度地提高。该技术成为该区块提高钻井速度的有效途径之一。
From the reality of the Yong 42 block,through the optimization of the PDC bits and the screw drilling tools in the third open section of directional wells,at the same time,the author optimized the drilling parameters,the bottom hole assembly and the system of drilling fluid,which improved the average ROP greatly.This technology becomes one of the effective ways to improve the drilling speed in this block.
