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℃.
