Automatic matching for interwell tracer production curve

Based on the theory of convective diffusion,the theoretical equation for interwell tracer production concentration is derived by the stream tube method.The conventional interpretation method yields low interpretation accuracy as it needs artificial adjustment of interwell and injection parameters to match the production curve.The genetic algorithm is used to establish a new interpretation model,which automatically matches the interwell tracer production curve.Given ranges of the parameters,the production curve may be automatically matched without artificial adjustment.The application results show that the model converges quickly with high interpretation accuracy.
