Oil Drilling Grade CMC/PAC
Oil Drilling Grade CMC/PAC: CMC/PAC is a high-purity, high-efficiency slurrying agent. It has strong salt resistance and temperature tolerance, compatible with sea water and saturated brine. It helps stabilize soft soil structure, prevent collapse of wall of a well. It can improve mud-making volum, reduce filteration loss.It can improve drilling speed and oil Production rate.
