【摘要】：由于研究区属于复杂断块油气藏,随着油藏不断地开发,开采效果不断变差,因此有必要通过开展油藏精细描述,并结合现阶段的开发状况分析剩余油分布区域。在以上研究的基础上对研究区进行调整部署研究,改善开发效果。利用三维地震资料解释等方法重新认识于楼油田的地层构造、沉积及储层的特征,利用物质平衡法、动态分析法及数值模拟等方法预测剩余油平面及纵向上分布规律,计算剩余油储量,分析影响剩余油分布的主要控制因素,从而得到剩余油气藏的分布情况,并以此为依据,分析目前层系、井网、注采压力系统的合理性及各种增产措施的效果,提出调整意见,经过调整部署,为该区增储复产提供依据,充分挖掘剩余油潜力。通过以上研究得到结论如下:该井区的砂体分布受沉积相带控制明显,水下分流河道等主相带区砂体厚度大,物性好,油层发育。由于河道相带窄、平面变化快,造成砂岩组和小层砂体纵、横向非均质性强,油水关系复杂;经过对各套油层分布与生产动态的关系的分析,研究区的油井生产状况的差别很大,这主要与油层分布有关,S1下段油层的生产状况明显好于S3段;而且受连通程度低的制约,注水补充能量只从完善井网是不能实现的,必须采取灵活多样的方式才能提高开采效果。
[Abstract]:The study area belongs to complex fault block reservoirs, along with the continuous development of mining reservoir, the effect of continuous variation, it is necessary to carry out fine reservoir description, and combined with the development present situation analysis of remaining oil distribution area. On the basis of the above research in this area to adjust the deployment of research, to improve the development effect. The stratigraphic structure using 3D seismic data interpretation method to recognize building oilfield, sedimentary characteristics and reservoir, using the material balance method, dynamic analysis method and numerical simulation method to predict remaining oil in lateral and vertical distribution of remaining oil reserves calculation, analyzed the main control factors of remaining oil distribution, so as to obtain the distribution the residual oil and gas reservoirs, and on this basis, the analysis of the current layer, well pattern, injection production pressure system and the rationality of various kinds of stimulation effect, bring forward the adjustment suggestion, after adjustment The deployment, provide the basis for the increasing reserves and production, to fully tap the potential of remaining oil. Through the above research conclusions are as follows: the wells sandbody distribution was controlled by sedimentary facies, underwater distributary channel main facies belt of sand body thickness, good physical properties, reservoir development. As the river narrow facies belt the plane, change quickly, resulting in sandstone group and small layer sand body vertical, lateral heterogeneity, complex oil-water relation; through the analysis on the relation between the reservoir distribution and production performance, production wells in the study area difference is very big, mainly with the reservoir distribution, S1 reservoir production situation is better in the S3 section; and by restricting the low degree of connectivity, water supply energy only from the perfect well network is not realized, must adopt various ways to improve the mining efficiency.
