Production Splitting Method for Commingled Production Reservoir Based on Automatic History Matching of Single Well

Abstract The interlayer interference is very serious in the process of water flooding development, especially when reservoir adopts commingling production. implementation various mitigation measures requires that production performance parameters and remaining oil distribution each layer should be clearly defined, accurate splitting wells key. In this paper, five-spot pattern simplified to a single well model commingled centered on well. results are obtained through automatic history matching performance. comparison between calculation method numerical simulation shows simple, accurate, practical. field application, for multilayer without simulation, can quickly accurately realize according development data.
