fluid density

The result of analysis indicated that match between formation and bit is the key fac-tor affected PDC bit's drilling and drilling fluid density is the key measures for the drilling result of PDC bit, which is just on contrary with roller bit.

分析表明：影响PDC钻头钻进过程的关键因素是钻头与地层的匹配，钻井液密度已成为影响PDC钻头钻进效果的关键措施，这一点与牙轮钻头相反。
