The Optimization Research Of Inversion Methods Of Interwell Dynamic Connectivity Based On Capacitance-resistance Model

At present,inversion methods of interwell dynamic conductivity based on Capacitance-Resistance model have been more and more used.However,there are still some problems,for example,the missing of the judgment of the quality of the input data: we still have no reliable method to evaluate the effection of the variation of the reservoir properties on the results of the model,moreover,researchers often do not know the minimum amount of the sample data that is required;besides,the basic assumption often can not be satisfied: the bottom hole pressure of the production wells have changed but was not well logged,or a production well be shutdown for a long period of time,in such a situation,the Capacitance-Resistance model(CM model)may not bring authentic results.It is necessary to optimize and expand the CM model.In this thesis,optimization for CM model including: an evaluation method for the quality of the input data has been set up,including two parameters: CM number C-reflecting the effection of the reservoir properties,reasonable range: 6-134(metric unit);sample parameter ratio L-reflecting the effection of the amount of sampling data,reasonable range: L?7.The Segmented CM and Compensated CM have been introducted and also be validated for their reliability.Besides,the optimized design of the usage of the CM model is also discussed.
