Oil drilling field

Introduction

CMC is an ether derivatives of natural cellulose after chemical modification.it is a kind of water-soluble glues, both in cold and hot water with the features of bonding, thickening, emulsification, dispersion, suspension, stability, film, and so on

Applied range

A kind of water-soluble glues (hydrosol) with good performance

Function
As drilling mud agent, our CMC has a good resistance to salt,high temperature and filtration, it can be used for the preparation of the various kinds of drilling fluid and for the maintenance of oil drilling to improve fluid performance. Dosage
Drilling agent                      0.4-0.6%
