【摘要】 剩余油分布规律研究是一项世界性难题,也是地质、地球物理和油藏工程等不同学科领域的前沿性课题。它是油田开发调整、改善油藏开采现状及提高采收率的基础,更是油藏经营管理决策的重要依据。当前剩余油分布规律研究的相关学科前沿,以开发地质学和油藏工程学为指导,综合应用地质、地震、钻井、测井、取心、分析化验及开发动态等资料研究(特)高含水期剩余油分布规律将成为必然趋势。吉林前48区块属于低渗透油藏,本文对其现状及开发历史作出简要阐述,通过开发效果综合评价,注入压力、注水状况,注入孔隙体积与采出程度关系曲线、注入波及体积等开发效果进行评价,分析影响该块水驱开发效果的主要因素。利用油藏动态综合分析、水驱油藏剩余油分布预测的φ函数法开展剩余油分布规律研究。针对目前前48区块开采现状及开发问题,提出了储量挖潜措施,进行加密井调整。通过开发指标预测计算,得出前48区块经济评价。更多还原

【Abstract】 The rule of remaining oil distribution is a difficult problem in the whole world and is also the most advanced subject in the area of geology and geophysics and reservoir engineering. The remaining oil is the basis of developmental adjustment and, improvement of production and oil recovery. In addition, it offers the significant basis for the strategy of reservoir management. Nowadays, the advanced subjects on remaining oil is under the guide of developmental geology and reservoir engineering and combines geology, drilling,well testing and developmental performance, which is the trend of studying remaining oil during the high water-cut period.In order to make sure the steady and increasing production of Qian-48 block and define the optimization research plan of development, the research of flow unite is made analysis as to the low permeability reservoir of Qian-48 block and the flow unit is obtained on the basis of phase control. Ratio of injection to production and some other related factors, especially the degree of water flooding, the relation between ration of injection to production and pressure and injecting speed, injection pressure, water sweep, well pattern, evaluation of water flooding is given out. The influence of water flooding, well pattern and water sweep are on recovery is discussed and two method of predicting remaining oil are used:Φfunction and reservoir numerical simulation. Optimization developmental plan is given and economical evaluation is raised through development index.更多还原
