【摘要】：葡108区块沉积环境为三角洲前缘相沉积,储层砂体在平面上以水下分流河道微相砂体为主分布,在南北方向上主为要条带状展布,在平面的连续性比较差。当油田进入开采后期从而油田进入高含水的后期时候,油田开发会受砂体展布特征等的影响,葡108区块剩余油分布复杂而零散,从而制约着油田开发效果。因此,在油田开发中我们把揭示剩余油在地下的分布规律,余油储量、空间分布等特征及地质因素、注采状况之间的关系进行比较分析是挖潜剩余油、提高驱油效率及原油采出程度的前提和基础。本文通过对葡108区块进行地质模型的建立然后综合考虑利用地质、测井、地震和生产动态等数据资料,从而开展了对葡108区块地质特征油藏构造等再认识,从而弄清了窄小河道在砂体上的展布特征规律。然后在此认识的基础上,综合动态监测等有用资料,结合油藏数值模拟技术,开展了油藏剩余油分布特征的研究,从而弄清了各种类型剩余油在地下分布特点,提出有效挖潜措施,为达到提高水驱波及体积、改善油层水驱状况目的。采用油藏精细数值模拟等技术、剩余油形成与分布描述等技术以及预测等在内的技术,完善开采不完善油田剩余油的挖潜研究以及治理方案,为解决特高含水期油田剩余油进一步挖潜提供了经济有效的方法和途径,具有广泛的适用性。
[Abstract]:The sedimentary environment of Pu108 block is delta front facies sedimentary. The reservoir sand body is mainly distributed in the subaqueous distributary channel microfacies sand body, and in the north and south direction it is the main strip distribution, and the continuity in the plane is relatively poor. When the oilfield enters the late stage of production and the oilfield enters the late stage of high water cut, the oilfield development will be affected by the distribution characteristics of sand body, and the remaining oil distribution of Pu108 block will be complicated and scattered, which restricts the development effect of oil field. Therefore, in oil field development, we compare and analyze the relationship between remaining oil distribution law, remaining oil reserves, spatial distribution, geological factors and injection-production conditions. The premise and foundation of improving oil displacement efficiency and crude oil recovery degree. In this paper, the geological model of Pu108 block is established and the geological data, such as geology, logging, seismic and production performance, are considered synthetically, so as to develop a new understanding of the geological characteristics of reservoir structure in block GU108. The distribution characteristics of narrow channel on sand body are clarified. Then, on the basis of this understanding, combining the useful data such as dynamic monitoring and reservoir numerical simulation technology, the distribution characteristics of remaining oil in reservoir are studied, and the distribution characteristics of various types of remaining oil are clarified. In order to increase the swept volume of water flooding and improve the water flooding condition of oil reservoir, the effective measures of tapping potential are put forward. Using techniques such as reservoir fine numerical simulation, residual oil formation and distribution description, prediction and so on, to improve the research and treatment of remaining oil in imperfect oil fields. It provides an economical and effective way to solve the remaining oil potential in the super high water cut oil field, and has wide applicability.
