Drilling grade CMC sodium carboxymethyl cellullose  API 13A CMC-HV CMC-LV

Product Name: Sodium Carboxymethyl Cellulose Oil drilling Grade

CAS#: 9004-32-4

Physical and Chemical Feature:

Sodium Carboxymethyl Cellulose is an anionic linear macromolecular structure cellulose ether. White or ivory fiberized celluflour or white powder, oderless, tasteless. Easily dissolved in cold or hot water to form a clear solution of certain viscosity.

 

Application

CMC 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.

Usage: add to mud directly or glue solution preparation.
