【摘要】：目前,南一区东部高台子油层是萨中开发区第三个水驱精细控水挖潜示范区,实施以小层挖潜为核心的精细控水挖潜,并将在2014年进行新井产能建设,部署三类油层加密调整井。南一区东部高台子油层目前综合含水已超过95%,对高台子油层地质特征取得深入的认识,才能实现精细挖潜有的放矢、挖潜方式合理有效。该区块以往所开展过的地质建模是基于常规储层沉积相描述开展的,所取得认识难以满足该区块开发精细调整挖潜的需求,有必要基于沉积微相和井震结合构造研究成果,开展井震结合精细地质建模,有效支持开发潜力及开发效果系统分析,设计科学的挖潜方式,改善区块开发效果。同时,通过该项目实施,建立相应的技术方法,进一步提高精细油藏描述能力和水平。针对该项目的要求和难点,时刻围绕着井震联合这一中心,以GeoFacies、Petrel软件为主要工作平台,利用测井、地震、地质资料,优选地震反演方法开展储层精细描述,采用井震结合的方法,进行构造框架模型的搭建,以沉积微相为约束条件,应用地质统计学理论建立储层参数模型,揭示构造和储层空间分布特征,建立一套井震结合储层精细描述与三维地质精细建模方法。在此基础上,对研究区域进行了数值模拟研究,在历史拟合的基础上,根据剩余油分布规律,对区块开发潜力进行研究,并提出具体的调整方案;对提出的专项和单井调整方案给出方案预测结果并进行优选。
[Abstract]:At present, the Gaotaizi oil reservoir in the eastern part of Nanyi District is the third demonstration area in Sazhong Development Zone for water drive fine control water potential control. It has implemented fine water control and tapping potential with small layers as the core, and will carry out production capacity construction of new wells in 2014.Deployment of three types of reservoir infill adjustment wells.At present, the comprehensive water cut of Gaotaizi reservoir in the eastern part of Nanyi area has exceeded 95%. Only by making a deep understanding of the geological characteristics of Gaotaizi reservoir, can it be realized that the precise tapping of potential can be targeted and the way of tapping potential is reasonable and effective.The previous geological modeling in this block is based on conventional reservoir sedimentary facies description, so it is difficult to meet the needs of fine adjustment and tapping potential in the development of this block. Therefore, it is necessary to base on the research results of sedimentary microfacies and well shock combined structure.Well shock combined with fine geological modeling can effectively support the systematic analysis of development potential and development effect, design a scientific way of tapping potential, and improve the development effect of block.At the same time, through the implementation of the project, the corresponding technical methods are established to further improve the fine reservoir description ability and level.In view of the requirements and difficulties of this project, focusing on the center of combination of well and earthquake, taking GeoFacies-Petrel software as the main working platform, using logging, seismic, geological data, and selecting seismic inversion method to carry out fine reservoir description,Taking sedimentary microfacies as constraint condition, the reservoir parameter model is established by using geo-statistics theory to reveal the spatial distribution characteristics of structure and reservoir.A set of methods of well shock combined with reservoir fine description and three-dimensional geological fine modeling are established.On this basis, the numerical simulation of the study area is carried out. On the basis of historical fitting and according to the distribution law of remaining oil, the development potential of the block is studied, and the specific adjustment scheme is put forward.The prediction results of the proposed special and single well adjustment schemes are given and the optimal selection is carried out.
