Experimental Analysis of Gas Holdup Measured by Gas Array Tool in Gas–Water Two Phase of Horizontal Well

In the gas-water two phase of horizontal well, gas holdup is usually obtained by inverse calculation water measured array capacitance probes. Gas Array Tool (GAT) has been developed to directly measure holdup. This instrument introduced into China and its simulation experiment in flow wells carried out for first time study applicability measurement. Firstly, response principle measurement method GAT are analyzed; secondly, experimental data under different flowrates, cut, cable speed plotted finally, Capacitance (CAT) compared using an interpolation algorithm. It found that optical fiber probe consistent stable. also proves accuracy identification test conditions GAT, which lays a foundation further measurement, interpretation, field future.
