Gas Cap Reservoir Collaborative Development Adaptability Research
At present, the development of gas reservoirs at home and abroad mainly has two kinds of depletion and water flooding development. Whether it is depletion or water injection development, the development effect is affected by many factors. In this paper, the single-factor and multi-factor orthogonal analysis method is used to study the influence of formation development, gas index, oil ring thickness, condensate content, permeability, vertical/horizontal permeability and so on. Through sensitivity analysis, the main controlling factors affecting the development effects of reservoirs are selected. According to the results of the numerical simulation, the screening board for gas cap reservoirs are obtained, which is a good reflection of the relationship between the optimal development method and the geological parameters. This provides a reference for the optimization of the actual reservoir development scheme. Through the development of adaptability research under the main control factors, the rational development pattern of gas roof reservoirs under different geological characteristics is selected, which has certain guiding significance for the selection of reasonable development methods of such reservoirs.
