The invasion of drilling fluid is the main cause to the damage of fractured formation. The composite salt free-gel drilling fluid is got after analyzing the influence of different kinds of such soluble adulterant as organic salt and non organic salt on the performance of the solid-free drilling fluid and studying the condition to develop the free gel structure and the method to improve the fluid's high temperature stability and inhibitive property. The experiment shows that the apparent viscosity of this system is as high as 27000 mPas when the share rate is 0.3 r/min and the high temperature reaches at the stable level of 150℃ and the HTHP filtrate loss decreases to 15 ml at 150℃.

钻井液侵入是裂缝性储层损害的主要因素之一，实验分析了无机盐、有机盐等不同类型水溶性加重剂对无固相钻井液性能的影响，研究了无固相钻井液快速弱凝胶特性形成条件以及高温稳定性和抑制能力的提高方法，研制出的无固相复合盐弱凝胶功能性钻井液高温稳定性达到150℃，具有独特的流变性（0.3r/min黏度达到27000 mPas）和优良的抑制能力（150℃HTHP滤失量小于15 mL），成本远低于甲酸盐钻井完井液。
