为PDC钻头连续钻进进行钻井液性能控制

DRILLING FLUID PROPERTIES CONTROL FOR PDC BIT DRILLING

  • 摘要: PDC钻头具有钻进时间长、机械钻速高、起下钻次数少等特点,使用PDC钻头可大大提高钻井速度。但PDC钻头的使用效果与PDC钻头在钻进过程中短程起下钻的次数有很大关系,每次短程起下钻后机械钻速都要明显地降低。吐哈中原钻井公司通过在钻井液上做文章,围绕如何形成薄滤饼和如何减薄滤饼上下功夫,基本解决了PDC钻头起下钻阻卡问题,实现了PDC钻头连续钻进(中途不用短程起下钻),充分发挥了PDC钻头使用效果。

     

    Abstract: PDC bit have advantages of high penetrate rate,long bit life which saving tripping times so that the application of PDC bit can improve drilling efficiency. PDC bit application effect are limited by short tripping time to avoid borehole underguage during drilling, drilling rate always decreased after short tripping. Though improving mud properties such as mud cake, the PDC bit tripping problem have been solved, without short tripping.
