Product Name:Poly Anionic Cellulose (PAC)

 

Application

PAC has good heat resistance and salt resistance, antibacterial and strong. Mud flow mixing with PAC has good water loss, inhibition, high temperature resistance.. 

PAC of  Oil Drilling grade has high degree of substitution and good uniformity.
1.Used in water-base mud of plain water, sea water and saturated brine:
Small usage, high yield; good anti-salt and anti bacteria property; reduce the fluid loss and improve the viscosity; strong flowing control and suspending ability.
2.Used in Drilling Fluid
Protecting the wall of oil well, prevent mud flowing away and carry crumbs; protect drilling bit, increase drilling speed and prolong its use period; reduce the fluid loss and the thickness of the mud cake; strong inhibition effect to shale hydration.
3.Used in Fixing Fluid
Protect the wall of the oil well; stop the fluid entering into the pores and cracks; control the fluid viscosity and heavy object suspension; prevent fluid loss
4.Used in Fracturing fluid
Bring stuffing into the cracks of oil well to establish osmosis channel; controll fluid entering into oil well structure to reduce fluid loss and lower the pressure.
