Introduction:
1) Sodium carboxymethyl starch (CMS) is a modified starch with carboxymethyl ether, which is superior to carboxymethyl cellulose (CMC) and is the best product to replace CMC.
2)CMS aqueous solution is stable and excellent performance, with bonding, thickening, water retention, emulsification, suspension, dispersion and other functions.
3) CMS in the process of oil wells as a slurry stabilizer, water retention agent, play a role in reducing water loss, improve the clay particles in the drilling of the role of coal particle stability.
4)CMS has little effect on the plastic viscosity of the mud, which has great influence on the power and shear force, which is beneficial to carry the cuttings, especially when the drilling salt is used, which can stabilize the drilling fluid and reduce the loss. Particularly suitable for high salinity, high PH value of saline alkali wells
