Application

(HEC) application in oil exploitation: In oil field well drilling, finish well , cement the well , is it split work liquid needed to operate to press. Well drilling (HEC ) can improve well drilling ability of carrying of liquid greatly, can effective cooling bit lengthen service life in time at the high-speed well drilling, improve the ability to resist calcium of the well drilling liquid . In mud of cementing the well being among the oar and low firm looks well drilling among the liquid, (HEC), fine water-retaining property can be prevented filtrating and entering the oil reservoir in a large amount from, improve oil well output, fine rheology performance reduce or reduce pump power and pump not to pigeonhole in addition (HEC). (HEC) can improve the output of oil gas, lengthen the life-span of the oil well and have broken glue rapidly completely to keep, it injures the low grade characteristic to the drill core that the content of residue is low. HEC is Hydroxy Ethyl Cellulose and is non-ionic. HEC is used to increase viscosity in clear brine fluids. HEC is compatible withother drilling fluid additives
