摘要:
提出了一种截面式结构的电导互相关流量测井仪,该仪器采用上、下游传感器结构,每个传感器的激励电极和地电极在同一截面上,内电极环为激励电极、外电极环为地电极。流体从内电极环与外电极环所形成环形空间流过时,在截面上扰动信号响应最明显,对上下游扰动信号进行互相关运算实现流量测量。依据电磁理论对传感器电力线密度分布情况进行推导,结果表明这种结构具有阻抗唯一性和良好的灵敏度。在多相流模拟实验装置上对仪器进行了试验,结果表明测得的互相关流量与标准流量具有很好的线性关系,线性度达到0.999 2,满量程精度在5%以内。
Abstract:
The cross section structure of the conductance crosscorrelation flow logging was presented, which adopted upper and lower sensor structure, and each sensor with exciting electrode and ground electrode was on the same section. The inner electrode acted as the exciting electrode and the outer one as the ground electrode. The disturbance signal in response on section was most obvious, when the fluid flowed through the ring space formed by the inner electrode ring and the outer electrode ring, and the flow could be measured by crosscorrelation operation on the upstream and downstream of the disturbance signal. The sensor power line density distribution was deduced according to the electromagnetic theory, the result showed that the structure has good sensitivity and impedance uniqueness. The instrument was tested by multiphase flow experimental device, the result showed that the measured correlation flow and standard flow has a good linear relationship, the linear degree reached 0.999 2, less than 5% of full scale accuracy.
