Oil drilling grade CMC & PAC

CMC and PAC play the role of reducing water loss and increasing viscosity in drilling fluid, cementing fluid and fracturing fluid, so as to protect the wall, carry drill cuttings, protect the drill bit, prevent mud loss and improve the drilling speed.

Main use

Product Application

CMC & PAC is used as a fluid loss reducer in drilling fluid. Its function is to reduce the fluid loss of drilling fluid as much as possible by forming a low permeability, flexible, thin and dense filter cake on the borehole wall. Used as suspending agent, plugging agent and thickener for low solid drilling fluid.

1. It has good temperature resistance and salt resistance

2, the product is rarely affected by mold, so as to stabilize and extend the existence period.

3, easy to disperse in all water-based drilling fluid, from fresh water to saturated salt water drilling fluid can be used

4. It can prevent fluid from entering pores and cracks, and can be used as fracturing fluid to control the loss of fluid entering oil wells.

5, as an oil fracturing agent, to provide fracturing fluid suspended sand performance, can significantly reduce the loss of filtration and thin mud cake, and shale water has a strong inhibitory effect.
