摘要
两相生产井中,油、气、水性质的差异使流量计非线性响应程度加大。要准确确定各产层的视流体速度,必须进行流体性质及仪器结构非对称性校正。本文从理论出发导出流量计在两相流动中的响应方程,有析影响解释精度的因素,给出准确求取视流体速度的计算方程及其相关的校正方法。附有实例。
The response of flowmeter in bi-phase producing wells is non-linear dueto the variety of oil, gas and water properties. It is necessary to correct for the effect of fluid properties and tool structure. This paper derives a theo-retical response equation of flowmeter in bi- phase producing wells. Factorseffecting the interpretation accuracy are analysed. A expression caleulatingaccurate liquid apparent velocity and correlation method are provided. Sameexamples are presented.
