多学科油藏研究在油田开发中的应用

油田经过多年开发使层系、井组的调整及措施井选井选层难度不断加大,聚合物驱后剩余油高度分散,同时油田开发进入特高含水期,水平井成为厚油层剩余油挖潜的重要手段。以细分沉积相研究为基础,应用多学科研究技术,搞清了剩余油分布规律,并提出相应的措施挖潜方法;运用三维地质建模研究,定量描述河道砂体内部隔夹层在空间展布,提出适用的后续水驱阶段剩余油挖潜配套技术;挖潜厚油层顶部剩余油,并确定水平井开采层位优选原则及水平井轨迹设计方法,这些措施都有效的改善了油田开发效果。

Application of Multi Subject Reservoir Studies in Oilfield Devlopment

It is more and more difficult to adjust layer system and well group and select measuring well for oilfield having developed many years.AS remaining oil highly discrete after polymer expulsion,meanwhile oilfield having developed extra high containing water period so that Horizontal well has become significant measure to exploit remaining oil in thick reservoir.It has known that the remaining oil distributing rule in base of subdividing research sedimentary facies and application of integrated reservoir studies and established corresponding methods to exploit remaining oil.With 3D geological modeling research definite quantity describe the interlayer in channel sand allocation in space and established favorite follow-up water flooding corresponding methods to extract remaining oil.It also can extract remaining oil in coping of thick reservoir and establish horizontal well productive reservoir optimizing principle and track design method.All these methods have effectively improve oilfield exploitation effect.
