Research On The Post Evaluation For The Productive Capacity Construction Project Of Oil And Gas Field

As the important industry of our country, oil and gas field construction is main artery of national economy. As non-renewable resource, petroleum is regarded highly by governments of all countries in the world especially, therefore how to realize maximal efficiency of oil field engineering construction and exploit operation and so on becomes the focal point. At present, The job of post-evaluation on oil field construction project has been paid more and more attention, through it we can collect and analysis the decision-making of establishment of project, construction and operation, production and management, influence and durative and so on of oil field construction project, and sum up the good aspects and bad aspects of oil field project as a whole。From it discover problems, sum up experiences, provide the improvement ideas, and provide use for reference for oil field project in the hereafter.Basis on analysis and study the relevance achievement home and abroad in a great quantity, this paper gives the concept of post-evaluation on oil field construction project and applies a theoretical frame of post-evaluation on oil field construction project, Focus on the various stages of post-evaluation, evaluation index system and comprehensive evaluation methods, establishes the theoretical system of post-evaluation on oil field construction project, and verifies the scientific nature and operable of theoretical method established by the through the example.First, this paper summarizes the current situation of post-evaluation at home and abroad, Analysis the Research Status and the existing problems of post-evaluation on oil field construction project. Since the job of post-evaluation started late relatively in our country, can not form the perfect system of post-evaluation. Based on the characteristic of the oil field construction project, Develop a real and feasible method system is very necessary. Therefore based on the current research result, we appraise a comparatively perfect theoretical frame of post-evaluation on oil field development and construction project. Secondly, we built a system systematically appraising theory method of post-evaluation on oil field development and construction project. It Point out eight main contents of post-evaluation on oil field construction project, including post-evaluation on Preliminary work, post-evaluation on oil gas Tibet geology project, post-evaluation on drilling project, post-evaluation on extract oil project, post-evaluation on floor project, post-evaluation on economic effect, post-evaluation on environmental impact and sustainability, and comprehensive post-evaluation.Third, these elements reflect the project management level and efficiency standards of different building phase on oil field. Each of the chapters based on the characteristics of the various stages, defined the concept and the significance studying on post-evaluation of various stages. Each chapter elaborates the major job of the stage and the main elements of post-evaluation, and identifies the main indicators and weight coefficient, makes the post-evaluation on every stage is operability.Fourthly, the evaluation method and the indicator system of the comprehensive post project evaluation for oil and gas field has been researched on, utilizing grey system theory to screen the material effect factors, establishing the synthesis post evaluation indicator system, constructing AHP, the fuzzy judgment method and the success law unifies effectively in order to construct the the appraisal frame of the success fuzzy judgment method.Finally, with the comprehensive post evaluation indicator system and the success fuzzy judgment method, the comprehensive post evaluation for the south area one of DaQing SaZhong oil field has been carried on, and the measure results has been analyzed system.
