Oil Drilling Grade CMC
- In drilling fluids, it effectively controls water loss, forms a high-quality mud cake on the well wall, protects the well wall and prevent the penetration and loss of water in the drilling fluid;
- In completion fluids, it is used to reduce filtration loss, thereby preventing fluids from entering voids and cracks. They can also control fluid viscosity and heavy object suspension.
- In fracturing fluids, it is used to rapidly increase the viscosity of the fracturing fluid, bring the proppant into the oil well cracks, establish a permeation channel, quickly reduce the filtration loss, and quickly increase the formation pressure to achieve the effect of transferring pressure.
