Application of Reservoir Numerical Simulation in Fluvial Facies Integrated Reservoirs
[Purposes]This paper aims to use reservoir numerical simulation technology to calculate and simulate the dynamic changes during the development process of the reservoir,predict the development status under different plans through the calculation of fluid flow status and numerical values within the grid,and predict the oil and gas production situation under different development plans.[Methods]Tar-geted parameter adjustment methods and dynamic model establishment are adopted for the type of fluvial facies integrated oil reservoirs.Based on the results of fine reservoir description and three-dimensional reservoir model,the dynamic data of all oil and water wells in the block since the oilfield was put into op-eration are used as the basis.[Findings]This article conducted numerical simulation on the eastern block of Dongying Depression,accurately fitting historical dynamics,and increasing the overall water content fitting rate from 85.3%to 92.7%.It also summarized the distribution pattern of remaining oil in this block,proposed four favorable development zones,and increased recoverable reserves by 123 000 tons.[Conclusions]Through the fitting of the whole block and single well,as well as the accurate de-scription of the formation development process and the dynamic change of the reservoir,the numerical simulation scheme of the reservoir can find the distribution position of the remaining oil and provide a credible scientific basis for formulating a reasonable development adjustment scheme.
