摘　　要：剩余油挖潜是提高石油产量的重要途径,合理划分单个油井的控制区域是制定有效挖潜措施的重要前提。文章结合石油开采原理和油藏工程师的实践经验,提出了水驱效果和水流方向2条启发式规则,并在此基础上提出一种自动划分单油井控制区域的方法。该方法首先基于水驱效果和水流方向选取给定油井的周围注水井,并依次连接周围水井形成多边形区域;若多边形中没有其他油井,则该多边形区域内与油井连通的区域即油井的控制区域,否则依据连通性和距离原则将多边形区域划分为多口油井的控制区域。文中提出的方法应用于自主开发的面向大庆油田的剩余油分析与辅助决策系统软件中,取得了良好的应用效果。Residual oil tapping is an important way to increase oil production.It is important premise and guarantee of developing effective tapping measures to assign reasonable control region for single oil well.Based on the principle of oil exploitation and reservoir engineers’practical experience,this paper concludes two heuristic rules:water flooding effect and water flow direction,and further proposes an automatic division method of control region for single oil well.The method firstly selects the surrounding injection water wells of the given oil well based the heuristic rules and connects the surrounding wells in turn to form the polygonal area;if there is no other oil well in the polygon,the whole polygonal area is assigned as control region of the given oil well,otherwise the polygon is further divided into some sub-areas according to connectivity and distance principle,and each sub-area is assigned to one oil well.The method has been applied to the self-developed software system of residual oil analysis and auxiliary decision for Daqing Oilfield,and has achieved good result.
