【摘要】 油田生产是采油工程系统中最基本最重要的环节。油田投入生产之后,就变成了一个规模大,管理幅度大,生产建设工序多的大系统,迫使决策者不可能仅仅依靠表面数据人为的、凭借经验对各油田生产做出战略性部署与规划。为此,采油生产状况评价体系依托采油工程辅助决策系统而建立,帮助决策者对油田生产规划提供科学依据。本文是用系统的观点,建立了采油生产状况评价体系。以国内油田采油工程生产数据库为依托,以油气田开发理论和综合评价理论为指导,从机械采油生产、作业情况和水平井生产三个方面进行研究分析,建立指标体系;并用主观赋权和客观赋权法建立评价权重体系;分别应用层次分析法、主成分分析法和数据包络分析法建立评价方案,方案先后从机械采油生产、作业和水平井生产三个方面进行单方面评价,最后结合三方面进行综合评价;建立了兼容度极大化模型和兼容度、差异度极大极小化模型,进而建立了采油生产状况评价体系;提供多个备选评价方案择优依据;并以国内油田采油工程生产数据为例,阐述了评价体系的建立过程。采油生产状况评价体系帮助石油企业管理层,提供决策依据,提高了油田生产管理的科学性和指导性。在确保实现油田开发评价、预测与规划的科学化和合理化,确保油田开发的稳步发展上,具有重要意义。更多还原

【Abstract】 The oil field production is the most fundamental and the most important link in the petroleum engineering. It is a large-scale system,with large range of management and many working procedures of production construction,which forced the decision-maker not to be impossible to depend upon the superficial data to make the strategic disposition and plan. Therefore, oil production status evaluation system was set up based on decision support system of petroleum engineering.This article has established the oil production status evaluation system with systematic viewpoint. Based on the production database of petroleum engineering,with oil&gas field development theories and comprehensive evaluation theories for guide, indicator system has been established, researching and analysing from three aspects of artificial lift production,job and the production horizontal well. Evaluation system of weights have been set up using by subjective and objective weighting method, established evaluation plans by using AHP, the principal component analysis and data envelopment analysis respectively,evaluated from three aspects, achieved comprehensive evaluation finally. Established the maximization model of Compatibility Degree and the maximin model of Compatibility and Different Degree, and oil production status evaluation system. Provide the criterion of superior ones of multiple alternative assessment plans. And taking the production database of petroleum engineering of China National Petroleum Corporation as the example, this paper expounds the process of establishing evaluation system.Oil production status evaluation system provides the basis for decision-making to enterprise managers, improving the level of scientific and guidance. Ensuring realization in oilfield development planning and assessment and prediction scientifically and reasonably, ensuring the steady development of oilfield, it has the vital significance.更多还原
