Application of Reservoir Simulation in Production and Development Management
摘要
At present, reservoir simulation is widely used in making reservoir development projects or reservoir adjustment projects. It is rarely used in reservoir production and development management. The main task of reservoir production and development management is to put forward stimulation measures and injection and production adjustment project. There are three main problems currently encountered. Due to the lack of measured single layer’s production data, it is difficult to optimize the injection and production adjustment project. It is difficult to quantify and predict the effect after carry out the stimulation measures. Therefore, it is difficult to optimize stimulation measures. Even if the stimulation measures is made, it is difficult to predict the effect after apply. It is hard to predict when key indicators such as pressure recovery inflection point and water cut inflection point will occur. It is impossible to quantitatively evaluate and compare reservoir development effects under different injection-production ratios. It is not possible to predict the changes of reservoir dynamics as soon as possible and optimize injection and production adjustment project according to the changes. After the application of the adjustment project for a period of time, the optimization can be continued according to the application effect. Taking an offshore reservoir as an example, to solve the problems encountered in reservoir production and development management, the application of reservoir simulation model is carried out. For the wells with test data, the virtual well is applied to ensure that the stratified water injection data of the reservoir simulation model is consistent with the measured data. According to the industry standards, the relevant parameters are adjusted reasonably, and the reservoir simulation model with high accuracy of history matching is established. By setting related keywords in the .sch file, the calculation and output of the stratified data are realized. Each time step of stratification, well group, well zone production data can be calculated. The prediction of measure adjustment project and the optimization of injection and production project are realized. After the implementation of the adjustment project, the tracking display appears application effect is good.
