Oil Drilling Grade PAC&CMC
PAC&CMC is used in oil drilling fluid, cementing fluid and fracturing fluid. In drilling fluid, it is mainly used as viscosifier, fluid loss reducer, and rheology control agent; in cementing fluid, it is used to control fluid viscosity, suspend heavy objects, and prevent fluid loss; in fracturing fluid, it is mainly used for carrying filling material to prevent fluid loss.
1. Application of "Linguang" CMC in fresh water, sea water and saturated brine
It has uniform replacement molecules, less dosage and high pulping rate;
Good salt and alkali resistance, strong antibacterial performance, easy to use;
The fluid loss reduction and viscosity increasing effects are obvious;
Rheology control, strong suspension ability.
2. Application of "Linguang" CMC in drilling fluid
Protect the drill bit and increase the drilling speed:
In low-solids and solids-free drilling fluids, it can significantly reduce fluid loss and reduce mud cake thickness;
It has a good inhibitory effect on shale hydration.
3. Application of "Linguang" CMC in cementing fluid
It can better protect the well wall and prevent fluid from entering pores and fractures;
It can better control fluid viscosity, suspend heavy objects, and prevent fluid loss.
4. Application of "Linguang" CMC in fracturing fluid
CMC products are used in fracturing fluids, which can efficiently carry "fillers" into oil well fractures, establish permeation channels, and effectively control fluids
Enter the oil well structure, reduce fluid loss and reduce pressure drop;
Ultra-high viscosity products can also replace guar gum, reducing production costs.
