摘　　要：Adding the polyamine inhibitor into drilling fluid can effectively strengthen the rejection capability and improve the rheological behavior of drilling fluid system. According to the analysis of the comparison of the physiochemical properties of the polyamine inhibitor, a polyamine polymer drilling fluid system was established by means of adding UAE polyamine into traditional polymer drilling fluid. Conventional properties and environmental influence of this system have been evaluated in this paper. The result indicates that the polymer drilling fluid system optimized by polyamine shows a high-performance, such as excellent rejection performance, better rheological and filtration properties, better environmental protection functions. Thus it can be used in high water-sensitive, high temperature, high pressure or vulnerable formation drilling operations.
