Research On Oilfield Enterprises Energy Consumption Evaluation And Optimize Decision-making

The sources of energy is an important material which human society rely for existing and developing, our country energy resources quantity is comparatively rich, but China's energy situation has become increasingly obvious restraint from the view of the development of China's energy supply at present. Low sum of our country the sources of energy equipment and control level falls behind relatively in unit GDP energy consumption about developed country. Energy consumption of the product is higher than main energy consumption average mainly level which aggravated further the sources of energy imbalance between supply and demand. Reduce the consumption of energy is an effective approach the energy needs, and important guarantee for China's economy sustainable development.As energy production enterprises, oil field enterprises have made enormous contribution for our country energy safety and economic development. In the procedure of oil and gas production, oil field enterprise also needs to consume large amount of energy and the energy consumption assumes the step by step growing trend with old oil field development degree of difficulty enlarging. Oil field enterprise realizes saving energy and reducing consumption may provide more sources, in the other hand it may reduces cost of production and strengthen the competition largely. It is rather prospective to make research on oilfield enterprises energy consumption evaluation and optimize decision-making, together with enormous difficulty and challenge.The major contents, methods and opinions concerned are as follows:The knowledge of energy theory is deepened. Based on the energy's multi-properties and the situation of oilfield enterprise, building-up the oilfield enterprise energy consumption evaluation indicators system which contain 5 subsystems and 18 indicators according to energy conservation. Choose PCA, TOPSIS and distance value analysis to build up evaluation model, to analyze oil field enterprises energy consumption current situation. Use gray model forecasting method and DEA theory to build up the forecast model of energy consumption and optimize it. Learn the fundamental trend and rough numerical value that enterprise energy needs, provide the necessary basis to optimize energy of enterprise according to enterprise expansion projects. Thinking that skill manages project to energy conservation is to realize main saving energy and reducing consumption means, use an approach which based on interval uncertain multi-attribute decision-making to research optimization of oilfield energy consumption program. Energy consumption of oil field enterprise has been analyzed and the relevant suggestions are put forward.The application of the oil field enterprise energy consumption evaluation model, the forecasting model of energy consumption and interval uncertain multi-attribute decision-making model built by this paper has very important theoretic and practical value to improve energy policy, strengthen energy regulation and operation of emergency management and achieve energy saving better.
