Product details
Polyanionic Cellulose PAC Drilling Grade PAC-HV 65%DescriptionPolyanionic cellulose in drilling fluid are used as fluid loss agent. The functions of polyanionic cellulose is through forming low permeability, flexible, thin and compact filtration cake on borehole wall, to reduce the fluid loss of drilling fluid as much as possible. Polyanionic cellulose used as suspending agent, plugging agent and thickening agent for low solid phase drilling fluid.

Applications1. Good temperature-resistant and salt-resistant properties.
2. Less influences from mould. Stable characteristics and prolong shelf life.
3. Disperse easily in all kinds of water base drilling fluid. Can be used in any drilling fluids ranging from fresh water to saline water drilling fluid.
4.Prevent fluid flow into pores and cracks. Used as fracturing fluid can control the losses arising from the fluid flow-in to the borehole.
5.Used as fracturing agent for oil production. Provide fracturing fluid sand suspension effect. Can apparently reduce fluid loss and thin filtration cake. Have strong inhibition effect of shale water.
