Introduction
(1) 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.
