A new type of conductance sensor has been studied to simultaneously measure both flow rate and water cut oil-water two-phase fluid in production wells. The is obtained by the ratio conductivity mixture that water, cross-correlation measurement, which can determine transit time flowing noise signals passing through upstream downstream sensors sensor. In this article, structure principles measurement are introduced. results dynamic experiment a multiphase loop situ application technology...
This article proposed a modified adaptive (MA) cross correlation method to measure the flow rate of high-water-cut oil-water two-phase flow. It asynchronously commences acquisitions upstream and downstream signals for according rate, enhancing degree between them, thus higher measurement accuracy transition time can be obtained. By limiting searching scope correlogram’s peak value in time-related observation window, calculation process is kept steady divergence due outliers effectively...
Due to long-term exploitation of oil wells, high water-cut oil–water two-phase flow has become one the most common types in offshore fields. In this work, two cross correlation flowmeters for type flow, i.e., newly proposed transverse excitation mode flowmeter and conventional axial flowmeter, are theoretically analyzed, numerically solved, experimentally compared. By building theoretical models, resolutions sensitivities sensors systematically compared demonstrate their abilities detect...
