In this study, systematic experimental investigation was carried out on single-phase fluid flow and vapor-liquid two-phase flow heat transfer in silicon microchannels.
本文主要针对微流体在硅基微通道内的单相和汽液两相流动与传热进行了系统的实验研究。
The reason is that the derived equation assumes the formation is homogeneous and fluid flow is single phase.
具原因在于公式推导中假定地层是均质的、 流体做单相流动等。
The present well test analysis methods are only suitable to single-phase flow in reservoir. In fact, multi-phase flow will occur after a certain long time reservoir fluid production.
目前，试井分析方法仅限于地层中的单相流动，而在油气田开发中后期，试井往往涉及地层中的多相渗流。
