低渗透油藏非线性流数值模拟与极限井距研究
STUDIES ON THE NUMERICAL SIMULATION AND CRITICAL SPACING OF NONLINEAR-FLOW LOW-PERMEABILITY OIL RESERVOIRS
摘要
Abstract
Since Darcy Law is unable to accurately describe the fluid flows in low-permeability oil reservoirs, the mathematical characterizing method of the start-up pressure gradients is developed for the reservoirs, the nonlinear flow model considering the above gradients and the mathematical model and numerical model with three-phase fluids are established. At the same time, the corresponding numerical simulation is generated as well. On the basis of the current numerical simulation softwares, the packges of the non-linear flow numerical simulation are programed and moreover they will be applied in the field model, the water-flooded process of low-permeability oil reservoirs with different permeabilities is simulated. The results of the preliminary simulation are generally coincident with the actual data of the field, thus the accuracy of the above method is proved, the chart board of the relation between the gradients and critical spacing is obtained, so the evidence for the development of low-permeability oil reservoirs are provided.关键词
