Study And Application Of Reservoir Numericalsimulation Software On Performance ModelMajor:Oil & Gas Development engineeringName:Ni TianluSupervisor:He yang Wang DemingABSTRACTReservoir numerical simulation uses the mathematics method to resolve the math model of oil-gas-water movement and research the movement rule of oil, gas and water in reservoir. It can serve for improving recovery ratio and economic benefit. It's a strong measure of designing the development plan in a new field, or the adjustment plans in an old filed. At present, there are a lot of commerical softwares of reservoir numerical simulation, such as WORKBENCH, VIP, et al. These softwares are integrated in pre-process, simulation, and post-process. But their weakness is the kernel of numerical simulation. For example, in a micro-fractured reservoir, the formation behaves as if it's homogeneous before injecting and the fractures have no effect. But after injected water, the fractures opened and the water hustled along the fractures. And if the injection well stopped injecting water, the fractures would gradually closed. The geological model for such reservoir is dynamic. Until now, all commercialsoftwares can't handle the dynamic geological model. So, it's necessary toIIdevelop a numerical reservoir simulation reservoir software for dynamic geological model.In this article, we have completed the following jobs:The method of reservoir numerical simulation for dynamic geological model has been studied.The numerical reservoir simulation software for dynamic geological model has been developed.By using the software developed, the Guanl62 oil field and obtained the distribution of residual oil has been simulated.This paper has the following main innovations:First obtain the method of reservoir numerical simulation for dynamic geological model.First develop the software for dynamic geological model, which can simulate the varied absolute permeability.
