八面河油田面14区剩余油分布数值模拟研究

On Numerical Simulation of Remaining Oil Distribution of Block Mian14 in Bamianhe Oilfield

八面河油田构造位置处于渤海湾盆地济阳坳陷东营凹陷南斜坡东段的八面河断裂构造带上,其北东与广利洼陷相连;西北紧邻王家岗断裂构造带;西南为草桥断裂构造带;南部抵达广饶凸起附近,面积约1100km2。经过20年的开发,油田已经进入高含水阶段,产量开始递减。用数值模拟的方法,分析并挖掘剩余油的开采价值可以有效的缓解生产压力,这将是下一步稳产甚至增产的确实可行的方法之一。

Bamianhe Oilfield is located on Bamianhe faulted structure belt on the eastern section of south slope of Dongying Depression of Jiyang Hollow in Bohai Bay Basin. It is connected with Guangli Depression in the northeast and Wangjiagang faulted structure belt in the northwest. It is Caoqiao faulted structure belt in the southwest and reaches Guangrao salient in the south. The area is 1100 km2. After 20 years development, the oilfield has already entered high water cut stage, and the output starts to decrease progressively. Analyzing and excavating remaining oil by means of numerical simulation can effectively alleviate production pressure, which is one of truly feasible methods to keep stable production and even to increases production for the next step.
