Thickener Carboxymethyl Cellulose CMC for Oil drilling
CMC &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.
