Research Of Robustness Evaluation On Ecological Environmental System In Shengli Oilfield

The activities of oil and gas resources development in oilfield enterprises on the one hand, provide the basic source of energy and material for the industrial development. On the other hand, the exploration and development of oil and gas resources have caused a certain effect on the original natural ecological environmental system, making oilfield ecological environmental system out of balance between and outside ecosystem and further speeding up circulation process of materials and energy. An increasing number of ecological environment problems restrict continuous, healthy and stable development of the oilfield ecological environmental system. To a certain extent, maintain the normal operation of the oil field ecological environment system, it is necessary to use scientific method to evaluate oilfield ecological environment system and the analysis, thought the balance of ecological environment system of measures to provide scientific basis. For the purpose, we through the following scheme are studied and discussed.Through a large number of collection and review of relevant literature, to the basic theory of oil field enterprise ecological environment system, coarse intensive Jane theory and the basic theory of robust control, from the current research situation, development course, basic concept and principle of the system, theoretical foil for the follow-up study. Analyzes the present situation of the ecological environment system of shengli oilfield, from the perspective of typology classification subsystem, as a foundation for later evaluation index selection. Identification of shengli oilfield, meanwhile, the influence factors of the ecological environment system robustness evaluation, find and analyze the current existing problems, and to find out the starting point and the foothold.Clear oilfield robustness evaluation index system of ecological environment system and according to the premise of according to the principle of ecological environment system of sh engli oilfield subsystem, analysis of influence factors of each subsystem, construct the evaluat ion index system of shengli oilfield ecological environment system. By determining the evalu ation function and selection evaluation index to the ecological environment system of shengli oilfield robustness for quantitative analysis. And detail of the system operation steps.In shengl i oilfield ecological environment subsystem of the system factors influence the actual data as the foundation, which is based on robustness evaluation system, using the functional operation of the evaluation system robustness evaluation, thought field application of robustness evalua tion system to provide data support.According to the research content to improve the ecologic al environment of shengli oil system robustness is proposed countermeasure and the suggestio n, and summarizes the research conclusion of this article.
