研究注水开发油藏储层动态变化特征的新方法

油田开发中,不稳定试井所反映的油藏动态信息非常丰富,但目前对试井资料的利用,还只是限于对单井单次试井分析得到的关于储层的定量信息.经过试井实践和大量的调研,结合其它资料对不稳定试井曲线做了对比研究分析,着重对不稳定试井特征曲线反映出来的油藏渗流模型进行了对比分析.认为:根据油藏模型变化,研究储层动态变化特征,进而进行油藏动态分析的方法是行之有效的;试井资料所得地层参数的精确性固然重要,但更重要的是要抓住它所反映的油藏渗流特性,充分分析油藏模型变化,研究储层动态变化,更好地认识油藏,加强油藏经营管理,指导油田开发.

Study the Character of Dynamic Variety of Container Rock in Waterflooding Oil Reservoirby Transient Well Curve

In oilfield development, the reservoir performance information which the transient well test reflects is very abundant, however, at present, the employment of well test data is only individual well and single well test. The author have had rich well test experience over the past years, investigating lots of datum, analyzing the transient well test datum, focusing on analyzing the reservoir geological model which is reflected by the transient well test curve, thereby, the author thinks that studying the formation dynamic by analyzing reservoir model variation is a efficient method, and analyzing the reservoir performance, at the same time, it is no doubt that the formation parameters obtained by well test datum, but what's important is that the reservoir characteristics information attained by it. So, we should analyze adequately reservoir model variation and study formation dynamic, accordingly, recognizing reservoir better, enhancing reservoir management, instructing reservoir development, which should be attached importance to in view of the investigators for analyzing the well test datum and reservoir development managers.
