平湖八角亭H油藏利用上部天然水层实施了一口自留注水井。由于其无法开展动态监测,笔者尝试通过数值试井技术得到了注水井不同注入条件下对应的生产井典型试井解释特征曲线,并分析了特点。在此基础上对比油井实际试井解释曲线特征,从而确定了自流注水井的动态特征。此方法对进一步挖掘试井解释的应用水平和效果、带动数值试井技术的推广和应用有促进作用,也为在常规试井解释无法应用的情况下提供了一种新的思路。

Water injection has been conducted into BJT H reservoir in PH oil field by using natural water from upper aquifer. Because performance monitoring has not been carried out, we use typical well testing interpretation curves from production wells through numerical well testing technique to solve this problem. On this basis, the characteristics of the well testing interpretation curves are compared, and the performance characteristics of the water injection well are determined. This method can promote the application of well testing interpretation, and the popularization and application of numerical well testing technology. It also provides a new way of well testing interpretation which can not complete with conventional well testing.
