流型对电容含水率计响应的影响

根据集流型流体电容含水率计的测量原理，按照模拟井实验结果，分析了流型对集流型流体电容含水率计响应的影响。在油水两相的情况下，电容含水率计环形测量空间内流型同样可以分为乳状流、泡沫流、段塞流和泡状流。乳状流时，总电容值小，含水率计响应相对于含水率和流量的变化率也小；泡沫流时，含水率计响应相对于含水率和流量的变化率较大；段塞流时，含水率计响应相对于含水率和流量的变化率很大；泡沫流时，总电容值大，而含水

Eftects of the Flow Regime on Response of the Packed type Fluid Capacitance Water Cut Meter.

The flow regime effect on the response of Packed type Fluid Capacitance Water Cut Meter (PFCWCM) is analyzed in the paper with the measurement principle of PFCWCM and the experiment results in simulated well. The flow regime can be emulsion flow,froth flow,slug flow and bubble flow in the annular measurement space of the PFCWCM. At emulsion flow regime, the capacitance is small and the variety rates of response to the water cut and flowrate are also small. At froth flow regime, the variety rates of response to the water cut and flowrate are larger. At slug flow regime, the variety rates of response to water cut and flowrate are the largest. At bubble flow, the capacitance is large and the variety rates of response to water cut and flowrate are small.
