Oil drilling grade CMC used in drilling fluid, fixing fluid and fracturing fluid as viscosifier, filtration reducer and rheology controller.
In drilling fluid, it can protect the shaft wall and prevent mud flowing away that enhances mining efficiency.
In fixing fluid, it is used to stop the fluid entering into the pores and cracks, control the fluid viscosity and prevent fluid loss.
In the fracturing fluid, it can carry stuffing and avoid fluid loss.
