Introduction

Greencel® CMC Sodium Carboxymethyl Cellulose Oil drilling grade

1.Application in fresh water,sea water and saturated water
*small usage,high yield.
*Good anti-salt and anti-bacteria property,convenient to use.
*Reduce the fluid loss and improve the viscosity significantly.
2. Applications in drilling fluid
*Protect the wall of oil well,prevent mud flowing away and carry crumbs.
*Protect drilling bit and increase drilling speed.
*In low solid or none solid drilling fluid,it can reduce the fluid loss and thickness of the mud cake obviously.
*Strong inhibition effect to shale hydration.
3. Applications in fixing fluid
*Protect the wall of the oil well,stop the fluid entering into the pores or cracks.
*Control the fluid viscosity,heavy object suspension,and prevent fluid loss.
Instant products,used in severe environment,it will be more convenient and simpler,and it will be more effective in mud allocating.
PAC&CMC can be used in drilling fluid,fixing fluid and fracturing fluid.In drilling fluid,it works as viscosifier,filtration reducer,and rheology controller;in fixingfluid,it is used to control fluid viscosity,suspend heavy objects,andavoid fluid loss;in fracturing fluid,it is uesd to carry stuffing and avoid fluid loss.
