In order to improve the efficiency of exploration and development of Yongjin Oilfield in Junggar Ba-sin, and to raise its success rate of drilling prospecting well, the mechanism of borehole wall instability in Yongjin Oilfield was determined after investigating and researching the present situation of instability wellbore wall about drilled well in Yongjin Oilfield and analyzing physical and chemical properties of rock in instability formation. The technology measure of borehole stability was formulated,and aluminium and amine drilling fluid with membrane and anti-caving capability was researched and developed. The evaluation experiment showed the drilling fluid system had high inhibition,high formation sealing function and good formation protection func-tion,and the return permeability of core was more than 90%, which could meet the demand of borehole stability and reservoir protection.
