Abstract

The invention relates to the technical field of petroleum exploitation. In order to solve the technical problem in the prior art that the optimization effect of the oil recovery process based on a unified model is poor, the invention provides a method for optimizing the oil recovery of a pumping unit based on a multi-working mode model, including: A variety of typical working condition types are obtained from the historical dynamometer data of the pumping unit; according to the various typical working condition types, the historical dynamometer data is classified, and the historical dynamometer data is classified into Each dynamometer data included corresponds to each typical working condition type; based on the dynamometer data corresponding to each typical working condition type, the neural network model of each typical working condition type is generated respectively; in the various In the typical working condition type, the type of the real-time working condition of the pumping unit is determined; based on the neural network model corresponding to the type of the real-time working condition, the oil recovery process of the pumping unit is optimized.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a method for optimizing oil production of a pumping unit based on a multi-working condition model. Background technique [0002] Process modeling and optimization integrates applied process modeling technology, optimization technology, advanced control technology and computer technology. Specifically, process modeling and optimization is to continuously calculate and change the operating conditions of the process while meeting the process production requirements and product quality constraints, so that the production process is always in the most economical state. Among them, the most critical is an accurate process model, a reasonable objective function and an efficient optimization algorithm. However, due to the time-varying and strong interference characteristics of the system, it is difficult to establish an accurate process model. Research hotspots in the fie...
