%X On the basis of studying the reasons of oil wells′ water rise rapidly in the second area of Dalugou and Baiyushan area of Jing′an oilfield, the paper studies the expansion characteristics, stability, and profiles improve ability in different environment of the “Water Flowing Direction Changing Agent” and “Associated Polymer”, which are the main components of the “pre-cross linked particle + PL profile control agent + Associating Polymer + Water flooding the flow of change agent” profile control system. This profile control system is used in field experiments too. The application and evaluation show that the system can effectively block permeability path and make deep flow shifted. It also has characteristics of long valid period, simple construction process and little environmental pollution. The systems can solve the problems of the reservoirs′ well-water rise fast (or flooding) and low recovery in second area of Dalugou and Baiyushan area, and provide technical support for the management of large pores or cracks reservoirs which produce water.
