Analysis of the causes of rising water content in the late stage of poly-drive in western block III of Area B and study of adjustment methods
Geological Research Institute of the Fourth Oil Production Plant, Daqing Oilfield Co., Ltd., Daqing, Heilongjiang 163000, China
Seizing the main contradiction of fast water-bearing rebound in western block III, analyzing the reasons of fast water-bearing rebound in response to the contradiction, meanwhile, by understanding the mechanism of polymer oil drive and combining the development effect of three western injection and gathering blocks, finding out that the main problem of slowing down water-bearing rebound is the establishment of pressure system, and therefore the corresponding management measures at the injection and extraction ends respectively.
Key words: Late poly injection / control of water content rise rate / injection pressure / injection and extraction system
