【摘要】：油田增產(chǎn)措施的實施是油田開發(fā)進入中期或后期的必要之舉。近些年來,隨著油田開發(fā)的不斷深入,各大油田的采出程度高,含水率急劇上升,剩余可開采儲量有效厚度較小、豐度較低,新儲量接替不足,油田開發(fā)的經(jīng)濟效益不斷下降。在地質(zhì)條件惡化、資金緊張的條件下,找到實施增產(chǎn)措施的作業(yè)時間及如何合理配置措施方案,提高措施有效率以及措施效益,使油田獲得更大的經(jīng)濟效益是各大油田企業(yè)面臨的新課題。因此,對油田增產(chǎn)措施效益優(yōu)化研究勢在必行。 本文在分析了油田開發(fā)過程和后期開發(fā)現(xiàn)狀的基礎(chǔ)上,對油田實施增產(chǎn)措施進行了概述,并總結(jié)了油田增產(chǎn)措施面臨的主要問題及油田實施增產(chǎn)措施作業(yè)時機分析及產(chǎn)量分析。隨后,簡要介紹了我國油田現(xiàn)行的主要的增產(chǎn)措施,并通過對增產(chǎn)措施效果傳統(tǒng)評價方法的評析,發(fā)現(xiàn)了傳統(tǒng)的評價方法存在不足。按照優(yōu)選方法的不同,將增產(chǎn)措施分為單井增產(chǎn)措施方案優(yōu)選和油田增產(chǎn)措施方案優(yōu)選。于是,本文將數(shù)據(jù)包絡(luò)分析方法(DEA)引入單井增產(chǎn)措施方案優(yōu)選中,在分析了影響增產(chǎn)措施效果評價主要因素的基礎(chǔ)上,建立了評價指標(biāo)體系和評價模型,并選取了某油田某油井進行了案例分析,得出了評價結(jié)果。最后,本文站在油田或整個區(qū)塊措施方案優(yōu)選的角度上,以目標(biāo)利潤最大為目的,建立了油田增產(chǎn)措施優(yōu)選模型,選取了某油田對增產(chǎn)措施優(yōu)選模型進行了應(yīng)用說明,并給出了措施優(yōu)選的保障性建議。最后得出本文的結(jié)論及成果。
[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.
