“最优钻井液是一种具有清洗钻井所必须的流速的钻井液,它具有一定的水马力去清洗在压力和转速下工作的钻头,从而获得最低的成本,且这种变量的组合,能导致迂到标准勘探层位和穿过目的层时为一稳定的井眼”。某些人们则附加有“对泥浆工程师来说易于控制和维护”。上述最优钻井液的定义可概括并适当的用泥浆的五个功用来表达:(1)冷却钻头和其穿过井底岩屑切入岩石的牙齿;(2)清除
“The optimal drilling fluid is a drilling fluid with the necessary flow rate to clean the well, which has a certain water horsepower to clean the drill bit working under pressure and speed for the lowest cost, and the combination of these variables, Can result in a stable wellbore that goes beyond the standard exploration horizon and through the target horizon. ” Some people have attached “easy to control and maintain for mud engineers.” The above definition of optimal drilling fluid can be summarized and properly expressed in terms of five functions of the mud: (1) cooling the drill bit and its teeth cut into the rock through rock cuttings; (2) removing
