高含水期油田井网优化组合——以下二门油田下层系为例

Well Pattern Optimization Combination of High Water Cut Oilfield: Case Study for Xia-Layer System of Xiaermen Oilfield

井网调整贯穿油田开发全过程,不同开发阶段由于目的不同而具有鲜明的针对性。以下二门油田下层系为例,根据高含水期剩余油分布特征及潜力类型,针对现注采井网的不适应性,结合高含水期调整的有关技术政策界限,制定高含水期井网优化组合原则,在此基础上进行井网优化方案部署。

Well pattern adjustment is through the overall process of oilfield development and has bright pertinence for the different aim in different development stage. This paper takes Xia-layer system of Xiaermen oilfield as an example and narrates well pattern optimization combination on the base of the remaining oil distribution and potential type of high water cut oilfield. The principle of well pattern optimization combination is given aiming at the inadaptability of injection-producing well pattern and combining with some technical and economic limits.
