欠平衡钻井条件下录井配套技术

Logging ancillary technologies under underbalance pressure drilling

欠平衡钻井虽然能够提高机械钻速,缩短钻井周期,但是也给现场地质录井工作带来了困难。通过对不同欠平衡钻井条件下对地质录井的影响分析,提出了相应的配套技术措施,为今后施工欠平衡录井积累了经验。

Although underbalance pressure drilling can improve the mechanical drilling rate,shorten drilling cycle,but also bringdifficulties to on-site geological logging,on which the analysis of influences under the drillings are carried out in this paper to put forwardrelative ancillary technical measures for future construction.
