摘要
流体界面的确定对油藏开发经济评价、储量计算以及布井和射孔方案的设计等是必不可少的基础性工作。虽然可用于确定流体界面位置的方法有多种 ,但每种方法并非在任何情况下种方法都能适用。笔者提出一种新的流体界面估算法 ,即毛管压力曲线法。文中以油水过渡带内的流体界面为例 ,阐述了该方法的基本原理和具体操作步骤。毛管压力曲线法具有原理简单、易于编程和所需资料少等优点。实际应用表明 ,其计算结果与实测数据非常接近 。
It is an indispensable fundamental work to locate fluid interface for making economic evaluation of oil reservoir exploitation, defining reserves, placing of well and designing perforation schemes. Although there are several methods of locating fluid interface, each method is not always suitable for any case. The author will provide a new method of capillary pressure curve for estimating fluid interface. The ultimate principle and detailed operation procedures of the method are illustrated in this paper taking fluid interfaces of oil-water transition zone as examples. The method based on capillary pressure curve has advantages of simple theory, easy to be programmed, and small amount of data needed. The application shows that the computing results of this method are very close to the measured data, and it could entirely satisfy the accuracy required by engineering computation.
