【摘要】：油田增产措施的实施是油田开发进入中期或后期的必要之举。近些年来,随着油田开发的不断深入,各大油田的采出程度高,含水率急剧上升,剩余可开采储量有效厚度较小、丰度较低,新储量接替不足,油田开发的经济效益不断下降。在地质条件恶化、资金紧张的条件下,找到实施增产措施的作业时间及如何合理配置措施方案,提高措施有效率以及措施效益,使油田获得更大的经济效益是各大油田企业面临的新课题。因此,对油田增产措施效益优化研究势在必行。本文在分析了油田开发过程和后期开发现状的基础上,对油田实施增产措施进行了概述,并总结了油田增产措施面临的主要问题及油田实施增产措施作业时机分析及产量分析。随后,简要介绍了我国油田现行的主要的增产措施,并通过对增产措施效果传统评价方法的评析,发现了传统的评价方法存在不足。按照优选方法的不同,将增产措施分为单井增产措施方案优选和油田增产措施方案优选。于是,本文将数据包络分析方法(DEA)引入单井增产措施方案优选中,在分析了影响增产措施效果评价主要因素的基础上,建立了评价指标体系和评价模型,并选取了某油田某油井进行了案例分析,得出了评价结果。最后,本文站在油田或整个区块措施方案优选的角度上,以目标利润最大为目的,建立了油田增产措施优选模型,选取了某油田对增产措施优选模型进行了应用说明,并给出了措施优选的保障性建议。最后得出本文的结论及成果。
[Abstract]:In recent years, with the deepening of oilfield development, the degree of recovery is high, the water cut is rising sharply, and the effective thickness of remaining recoverable reserves is small. Low abundance, insufficient replacement of new reserves and declining economic benefits of oilfield development. Under the condition of deterioration of geological conditions and shortage of funds, the operational time for implementing measures to increase production and how to allocate the measures reasonably are found. It is a new task for the large oil field enterprises to improve the effective efficiency and the benefit of the measures, so it is imperative to study the optimization of the benefits of the measures of increasing the oil field production. Based on the analysis of the oilfield development process and the present situation of the later development, this paper summarizes the measures to increase production in the oilfield. The main problems faced by the oil field stimulation measures are summarized, and the operation opportunity and production analysis of the oilfield production increase measures are analyzed. Then, the main production increase measures in China are briefly introduced. Based on the analysis of the traditional evaluation methods for the effect of stimulation measures, it is found that there are shortcomings in the traditional evaluation methods. According to the difference of the optimal selection methods, the measures of increasing production are divided into the optimal selection of single well stimulation measures and oilfield stimulation measures. In this paper, the data envelopment analysis method (DEA) is introduced into the optimization of single well stimulation measures. Based on the analysis of the main factors affecting the evaluation of the effect of the measures, the evaluation index system and evaluation model are established. An oil well in a certain oil field is selected for case analysis, and the evaluation results are obtained. Finally, from the point of view of the optimal selection of the oil field or the whole block measure scheme, a model of optimal selection of oil field stimulation measures is established in order to maximize the target profit. In this paper, the application of an oil field to the optimal selection model of production increase measures is illustrated, and the supportability suggestions for optimal selection of measures are given. Finally, the conclusions and results of this paper are obtained.
