摘要
在煤层气钻井中,循环介质的选择及应用具有极其重要的作用,34井在钻进过程中通过采用可循环微泡钻井液,有效地保护了储层,防止了漏失,提高了机械钻速,为单位增加了综合效益。
In CBM well drilling, the selection and application of circulating media has extremely important role in drilling Wells, No. 34 well drilling process through the mud by micro- bubble- based drilling fluids ,and effectively protect the reservoir,prevent loss ,raising mechanical drilling speed,in- creased comprehensive benefit for the unit.
