| Abstract: | In view of the serious balling in the Yangtze River Tunnel in San Yang Road Wuhan, the mechanism of the formation and removal of the mud package was analyzed by surface chemistry theory, focusing on the change of the affinity of the two phase interface, so as to achieve the purpose of removing the adhesion of the clay. Through the test of surface tension and wetting angle, the desorption efficiency of different surface active agents was compared, and the actual effect of the comprehensive drilling fluid was evaluated by the determination of the adhesion coefficient of mud cake. |
