致密油藏多级压裂水平井数值模拟及应用
Multistage Fractured Horizontal Well Numerical Simulation and Application for Tight Oil Reservoir
摘要
Abstract
With further progress of oilfield development all over the world,more and more tight oil reservoirs are being put in production. This paper established a mathematical model of multistage fracturing horizontal wells,and the multistage fractured horizontal well numerical simulation software was developed. The new software is verified by using the commercial software Eclipse. We matched the actual production data using this new software. Analysis was made about the fracture conductivity, SRV volume,SRV permeability,nonlinear coefficients,and initial pressure. Results show that the new software can effectively simulate multistage fracturing horizontal wells in the tight oil reservoir and reflect the nonlinear flow features. In order to increase productivity,the fracture flow capacity,SRV volume,and SRV permeability should be appropriately increased. On the other hand,the non-Darcy flow decreases the well productivity.关键词
