摘要
本文通过分析,认为金刚石钻头水力参数的设计对钻进效果具有重要影响,对不同的钻进条件和地层条件,若设计的水力参数与之相适应,则既能使钻头取得较高且稳定的时效,又有利于其寿命的提高;反之,则会出现钻头抛光、“打滑”的现象。
This paper ,by analysis, considers that the design of diamond bit hydraulic parameter exerts an important influence upon the drilling result. For different drilling conditions and different rock formations, a suitable design of the hydraulic parameter will not only result in a high and stable drilling speed ,but also favour the increase of the bit life. Otherwise, bit polishing and bit slipping will
