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.
