Numerical Simulation Research On Comprehensive Utilization Of Well Pattern And Layer Series In Xing-7Area

Applying Petrel geological modeling software, SPG layer geologic model and Fuyanglayer geologic model were built, respectively. In the process of building SPG layer geologicmodel, using variation function combined sedimentary facies data, reservoir random predictingmodel was built under sedimentary microfacies control, and vertical grid size is as small as0.2m. As to Fuyang layer, using the co-seism simulation, structural model and property modelwere built precisely.Using Eclipse software, numerical models of SPG and Fuyang were built respectively, inhistory matching, production conditions of producers and seperated layer water injection ofinjectors were matched. History matching parameters include OOIP, cumulative liquidproduction, water cut, and degree of reserve recovery. Based on fine history matching, theremaining oil in different sedimentary types of layers and in different sedimentary microfacieswas quantized, and well pattern adaptability was analysed.In consideration of layer series division, well pattern recombination, and Fuyang layerdevelopment,4reasonable development programs, whose well pattern consists of tertiary infillwells and tertiary recovery wells, were designed. At last, best program was choosed in the lightof forecasted development effect and economic evaluation. The result possesses greattheoretical guidance for the next development and deployment in researched region.
