Abstract

AbstractAfter many years of waterflooding development, the water cut of many old oilfields in China has reached 90% and entered the ultra-high water cut stage. The influence of the vertical and horizontal heterogeneity of the reservoir is intensified. The original stratigraphic division and well pattern deployment are often unable to meet the requirements of EOR. Therefore, it is an important task for decision-makers of Youyang development to carry out the research on formation reorganization and well pattern optimization in ultra-high water cut stage. Computer image processing and recognition play an important role in many fields, so it is necessary to take reasonable methods to improve the image quality. Based on the research and analysis of the current developed technical framework, this paper puts forward the method of improving image processing and recognition, and puts forward the application method of this technology, so as to improve the operation quality of the whole image processing system.KeywordsUltra high water cut stageHeterogeneityComputer image processingIdentification technology
