Two-Stage Separate Flow Measurement System Based on Compact Gas–Liquid Cylindrical Cyclone and Electrical Resistance Tomography

Abstract

In this study, gas−liquid cylindrical cyclones (GLCC) and electrical resistance tomography (ERT) are combined for gas−liquid separation and the flow measurement of liquid. Additionally, a two-stage gas−liquid separation system is suggested. To lower the measurement error in the tests, ERT was used to adjust the flowmeter measurement data. The findings of the experiment demonstrate that the two-stage separation device has a better separation effect than the one-stage separation device; additionally, the fluid flow pattern is more stable after passing through a separator. This study's liquid flow measurement technique has an error limit of only 10%, making it appropriate for measuring liquid flow in small-and medium-sized oil fields.
