Product description

This is a zwitterionic polymer fluid loss additive that combines strong inhibition, excellent resistance to salt calcium and temperature resistance. The agent is a non-water-soluble polymer obtained by copolymerization of various nonionic, cationic and anionic monomers. It has strong inhibition and can effectively control the hydration, expansion and dispersion of mud shale and cuttings . and it inhibit the formation pulping, and stabilize the borehole wall, have good fluid loss effect, and salt-resistant calcium can reach saturation. In the freshwater, seawater, and saturated brine drilling fluids, the fluid loss can be effectively controlled, and the mud cake quality is good. It has strong suspension capacity and cleanness. it can be used as the main polymer of high specific gravity freshwater and saturated brine drilling fluid. It has good sand-carrying effect ,and used in deep wells and ultra-deep wells. As an inhibitor and fluid loss reducer, it has good compatibility and resistance ,with a temperature resistance up to 200 ° C, thus can be combined with a variety of treatment agents. it is suitable for a variety of water-based drilling fluid systems on-site with simple application process, low maintenance, low drilling fluid costs, convenience in dispose.
