摘要
长期对油田注入聚合物,可能会造成地层堵塞和窜流,通过脉冲试井方法可以有效地判断出油藏的连通性。本文利用某油田的某一井组的一口观察井和三口激动井的测试数据,通过绘制井底压力曲线和脉冲试井分析图来分析井间地层连通性,对于提高驱替开发效果具有重要的指导作用。
It is very important to judge inter-well connectivity because of blocking and channeling flow appeared in the polymer-flooded reservoirs.In this paper,based on test data of an observation well and three perturbed wells,the inter-well connectivity was analyzed by the pulse testing and drawing the pressure tendency curve,which can provide some instructions for improving the displacement effect.
