Mao Weicheng Xie Junde Lv Zhigang Qi Baoliang Zhang Jianxin Pan Zhong (Petroleum Engineering Technology Research Institute of Henan Oilfield Company, SINOPEC, Nanyang 473132)  
JW101/B-W cross - linking system as profile control agent was developed. The effects of contents of components in profile control agent, acidity and temperature on the properties were examined. The shear stability and long term stability under high temperature of profile control agent had controlled gelling time and gel strength, good shear stability, high plugging rate, long term stability under high temperature and so on. It was suitable for profile modification of reservoirs under temperature of 80 - 110℃.
