Abstract:The heterogeneity of oil reservoir is the major internal factors affecting the oil-water seepage and oil and gas recovery of the reservoirs. The injection and production parameters have a great influence on recovery of heterogeneous reservoirs,and visualization study of microcosmic model is an effective method of determining the reasonable injection and production parameters of heterogeneous reservoirs. In this paper, seven experimental schemes are designed according to different injection-production methods and injection-production rate. Conducting water-driving-oil displacement experiments using visual dynamic simulation displacement experiment device, we study the influence on water flooding degree by physical property difference, well-pattern type and injection and production parameters of heterogeneous reservoirs. The results show that the change of water injection mode and injection and production parameters in high and low permeability areas have a great influence on recovery of heterogeneous reservoirs. The high recovery can be obtained by flooding according to certain ratio and surrounding equilibrium flooding in high and low permeability areas.
