生产测井油气水三相流动流型研究

Flow regimes of three phase flow research in production logging

三相流动是油田开发动态监测中常见而又难于解决的问题.目前多数研究者把油气水三相流动看作气液两相流动处理,即忽略油水之间的差异.三相流动中流型变化很复杂,在实验的基础上,对井中流体的流型进行了分析研究,建立了三相流动中流型变化图版,可以对井下流体流型进行合理的识别与判断.

Three phase flow of oil, gas and water is one common but also very difficult problem in exploitation and dynamic detecting of oil field. Nowadays most investigators consider three phase flow as gas and liquid two phase flow, which neglect the discrepancy of oil and water. Flow regimes vary complex in three phase flow, based on the monitoring experiments, this article searches the flow regimes in oil well and propose the flow regimes changing chart for three phase flow.
