摘要：
In view of the problems existing in the application of Capacitance Resistance Models (CRMs) to large-scale mature oil fields, Capacitance Resistance Model for Producers (CRMP) was selected for analysis, a simplified procedure for applying CRMP to large-scale mature oil fields was proposed, and some examples analyzed. A simplified derivation for CRMP was presented with consideration of characteristics of large-scale mature oil fields. Several strategies were presented to optimize the solution method, in order to shorten the solution time and speed up convergence rate. These include the implementation of a global optimization algorithm, parameter scaling, analytical development of gradient vector and Hessian matrix of the CRMP objective function and so on. These improvements enable the application of CRMP to large-scale problems. Stepwise history matching was shown to be an effective technique to improve reliability of the analysis. Example analysis results show that, the connectivity got by the presented method agrees with the practical production, which proves the reliability of the presented method. The connectivity of an injector to the nearby producers can be analyzed based on the CRMP simulation results, and the analysis results can be used for related study, such as determining current water injectors suited for CO2 injection, or current CO2 injectors not suited for CO2 injection. © 2017, The Editorial Board of Petroleum Exploration and Development.
