This paper studies how to use the PI technology to solve various problems existed in the process of shutting off water and controlling profile in heterogeneous reservoirs at high water-cut stage from the practice in oilfield. The method is used in Block P13, and all kinds of development indexes change well. The application results for that the PI technology is easy to be operated, the decision is strong scientific, accurate and practical, and which can be popularized to reservoirs or single well under different conditions.
