【 摘 要 】

In order to solve the severe problem of water breakthrough caused by the high heterogeneity of the reservoir and many rounds of water flooding in Bohai Oilfield, based on optimization of self-generating gas, foam and gel, a set of self-generating gel- foam system with good compatibility and better control of the deep profile in Bohai Oilfield was proposed. Through dynamic displacement and visualization experiments, the system was tested for its performance on water blocking. The results show that the system has a significant effect on the selective plugging of water channel, which can reduce the water production and improve the oil recovery.
