Drilling parameters typically include flow rate, pump pressure, standpipe pressure (SPP), pipe rotation (RPM), weight on bit (WOB), rate of penetration (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。

It is very important to measure the volume change of mud in mud pit for the safe drilling, the control of well blowout and the lost of circulation.

测量泥浆池中泥浆体积的变化对于安全钻井，控制井涌、井漏具有十分重要的意义。
