High Viscosity CMC Fluid Loss Additive For Water Based Drilling Fluids
CMC - HV In Oil-Drilling Industry:
High degree of substitution, good uniformity of substitution,high viscosity, low dosage, improve the performance of drilling mud.Good resistance to humidity ,salt and alkali, suitable for fresh water, sea water and saturated brine slurry.Stabilize soft soil structure and prevent collapse of wall of a well.Suitable for a wide range of mud systems, unstable solid content mud system.

characteristics:
(1) Uniform D.S, good transparency, controllable viscosity and filtration loss;
(2) Fit for water-based mud of fresh water, seawater and saturation salt water;
(3) Confected mud has good characteristic in reducing filtration loss, restraining and enduring high temperature;
(4) Confected mud has good rheology, it can restrain the dispersion and expansion of shale and clay in the high-salt medium, so that the pollution of the wall of a well under controlling;
(5) Made the soft soil structure stability to prevent the collapse of the wall;
(6) Slowed down the accumulate of solids in the mud, when well-drill get across the rock face;
(7) Restrained the turbulence in drill pipe, so that the circumfluence system can maintain a minimum pressure loss;
(8) Enhanced the yield of clay of the mud, reduced the filtration loss;
(9) Obtained stable foam mud.
