【摘要】 对应用于油井井下油水两相流含水率测量的电导传感器敏感场分布特性进行了研究。建立了传感器管道轴线位置含一柱状油泡时敏感场分布的理论模型,利用Schwartz交替迭代法求解了敏感场内的电势分布和电流密度分布,分析了不同油泡大小和所处位置对传感器输出结果的影响。为进一步深入研究电导传感器的响应特性奠定了基础。更多还原

【Abstract】 The sensitivity distributions of conductance probe for measuring water volume fraction of oil-water two-phase flow was investigated.The mathematical model of sensitivity field was built for conductance probe with a bubble at various axis positions.An alternating method of Schwartz was used to calculate the sensitivity distributions of the electrical potential and the current density.The effect of a bubble on the output voltage of a conductance probe was studied with various bubble sizes and bubble positions along the pipe axis.It lays a foundation for the future research on the response characteristics of the conductance probe.更多还原
