【摘要】：我国石油企业处于复杂多变的国内外宏观环境和石油市场环境中，面临油田资源稀缺性、市场局限性、环境制约性、成本递增性和收益递减性的发展规律等现实问题，为适应不断变化的环境，只有采取高效率、低成本的可持续发展道路。而油藏评价工作作为连接勘探开发重要的一环，为了提升油藏评价的准确性，保证油气勘探开发的效率，满足油藏评价工作的不同要求，有必要在油藏评价工作开展之前进行油藏评价方案优选，这对勘探开发成本控制与提升探明经济可采储量有重要意义。本文从油藏评价方案多属性入手，梳理了油藏评价方案多属性优选基础理论，构建了涵盖经济效益、风险、生态环境和社会效益的多层次指标体系。针对油藏评价方案属性重要性判断的不确定性，采用层次分析法对油藏评价方案多属性优选中的评价指标进行赋权，并将层次分析法在模糊环境下扩展，采用三角模糊数进行比较判断，，得出权重。考虑油藏评价属性值模糊性特点，将油藏评价属性值扩展为三角模糊数，构建了基于灰色关联分析的多属性优选模型。结合具体某油田区块五个方案对油藏评价方案进行多属性优选实证分析。
[Abstract]:The petroleum enterprises of our country are in the complex and changeable macroscopical environment and the petroleum market environment at home and abroad. They are faced with the development law of oil field resource scarcity, market limitation, environment constraint, increasing cost and decreasing income, etc. In order to adapt to the changing environment, the sustainable development path with high efficiency and low cost should be adopted. As an important link between exploration and development, reservoir evaluation can improve the accuracy of reservoir evaluation and ensure the efficiency of oil and gas exploration and development. To meet the different requirements of reservoir evaluation, it is necessary to select the reservoir evaluation scheme before the reservoir evaluation work is carried out, which is of great significance to the cost control of exploration and development and the promotion of proven economic recoverable reserves. Starting with the multiple attributes of reservoir evaluation scheme, this paper combs the basic theory of multi-attribute optimal selection of reservoir evaluation scheme, and constructs a theory that covers economic benefits and risks. The multi-level index system of ecological environment and social benefit. In view of the uncertainty of attribute importance judgment of reservoir evaluation scheme, AHP is used to empower the evaluation index in multi-attribute optimal selection of reservoir evaluation scheme. The analytic hierarchy process (AHP) is extended in the fuzzy environment, the triangular fuzzy number is used to compare and judge, and the weight is obtained. Considering the fuzziness of reservoir evaluation attribute value, the reservoir evaluation attribute value is extended to triangular fuzzy number. A multi-attribute optimal selection model based on grey correlation analysis is constructed, and an empirical analysis of multi-attribute optimal selection of reservoir evaluation scheme is carried out in combination with five schemes of a specific oilfield block.
