Drilling parameters typically include flow rate, pump pressure, standpipe pressure (SPP), pipe rotation (RPM), weight on bit (WOB), rateofpenetration (ROP) and pit volume (PVT).
流量、泵压、钻压以及机械钻速等常用钻井参数还可用于监测井涌和泥浆漏失。

KQC series of air hammers used in gas drilling can solve certain problems, such as lower ROP(RateofPenetration) and well deviation, which occurred in mud drilling in above medium hard formation.
