The Integral Optimization Method of Oilfield Production System

Abstract

Based on the study of the various flow patterns of the oilfield production system, the oilfield production system is divided into five relatively independent subsystems by node analysis. The nodes are the connection points of two adjacent sub systems, the dynamic parameters of flow and pressure are passed. According to the principle of balanced offtake, the energy loss in each subsystem is determined, and the theoretical model of the energy management of the ground pipe network of the production system was established. An example of energy consumption analysis in Daqing Xinghelian area, the integral optimization method is presented. The results show that the energy consumption of the production system in the region can be well represented by the established energy consumption model. The seepage of the reservoir is the largest in the whole production system, which is 40.2%. The reservoir can improve its seepage capacity by means of fracturing, better grading of sewage treatment process, improve the level of oil and water wells.
