Design Of Natural Gas Distributed Energy Stations System In Oil Field Based On Programming Model

The distributed energy resource system of the oil field natural gas, as a new branch of the application of the distributed energy resource technology, can realize the provision of a variety of energy, the comprehensive utilization of energy and close location to the users, with the different features of stable energy and limited supply of natural gas. At present, there is little study on design of natural gas distributed energy stations system in the oil field, so the study on the design of natural gas distributed energy stations system in oil field is highly valued in application and wide prospect.This thesis establishes programming model to solve the system optimization problems of natural gas distributed energy stations in the oil field. This thesis first analyzes the problems in design of natural gas distributed energy systems and gives the solutions; then establishes the programming models of the typical natural gas distributed station's system and the one in the oil field; finally finishes and appraises the design of natural gas distributed energy stations system in the oil field based on programming model.Here are the main content of this thesis:(1) The demands of natural gas distributed energy stations system design. The methods and principles of the design are analyzed based on the system features and users' demands. System can't meet the need of economy in the circumstances of the various and flexible need from the users. So the method of establishment of the programming models is proposed.(2) Programming model of natural gas distributed energy stations system in oil field. The typical natural gas distributed energy stations system is defined and the system's designing requirement is analyzed to confirm the programming target's types and quantities by virtue of the analysis of system's inner regularity and reasonable assumption to establish system characteristic function. The objective function is designed to analyze the limitation of system design implementation and build the constraint condition, and then the typical programming model is established. Based on the system characteristics of oil field natural gas distributed energy station, the highest gas consumption target is increased and the first-level target is switched to calculate maximum term benefit and form the programming model of the oil field gas distributed energy stations system.(3) The suitability and effectiveness of the model are verified in the application. The operation parameters are optimized from No.89 Xinjiang oilfield gas distributed energy application model. According to the system optimization scheme, the construction project is built, on the basis of which the project economic evaluation is made by constructing the project evaluation method, and income index increased significantly by comparing to the industry benchmark, which proves that the system configuration with efficient economy can be obtained by the programming model.The thesis is applicable to the design of the efficient oilfield gas distributed energy stations system, which can help to reduce the workload and improve the economic benefit of the system, and furthermore which can be widely used in designing oil field gas distributed energy stations system by perfecting the database.
