Phase flow-rate measurements of multiphase gas-liquid flow
This article considers problems of technological control of oil wells flow-rate as well as measurement techniques of gas-liquid multiphase flow. Some new method of phase flow-rate determination, which combines correlation and optical measurement techniques, is proposed. That is, two optical sensors are installed at the fixed distance from each other on the horizontal pipe. Information, received from these sensors, provides possibility of determining phase flow-rate by correlation function. Some block-diagram of the measurement system is shown.
