低密度水泥是解决低压易漏井固井水泥浆漏失的主要途径。
A composite light cement system is developed to solve the problem of cement loss during cementing in some Wells.
另外还要挑战紧公差段、尽量避免泥浆漏失，同时避免泥浆泄露至钻台。
Additional challenges included running through tight tolerances, minimizing mud losses, and avoiding mud spills on the rig floor.
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。
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).
