KimaCell® PAC HV Polyanionic Cellulose is a water-soluble glue that can be dissolved in cold water and hot water. Its aqueous solution has the functions of bonding, thickening, emulsifying, dispersing, suspending, stabilizing, and film-forming. As a treatment agent for drilling mud, PAC HV has good salt resistance and temperature resistance, high slurrying rate, and low fluid loss. It can be used in the preparation of various drilling fluids, and maintain and improve the performance of drilling fluids during drilling.
As an oil recovery fracturing agent, PAC HV can improve the sand suspension performance of fracturing fluid, reduce fluid loss and frictional resistance, and effectively transmit pressure.
KimaCell® PAC HV is mainly used in oil drilling fluid, cementing fluid and fracturing fluid.
The replacement molecules are uniform, the dosage is small, and the pulping rate is high;
Good salt and alkali resistance, strong antibacterial performance, and easy to use;
The fluid loss reduction and viscosification effects are obvious;
Rheological control and strong suspension ability.
Protect the well wall, prevent mud loss, and carry cuttings;
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.
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.
PAC products are used in fracturing fluids, which can efficiently carry "fillers" into oil well fractures, establish permeation channels, and effectively control fluid entering into oil well structures, reducing fluid loss and pressure drop;
Ultra-high viscosity products can also replace guar gum to reduce production costs.
