Online trace oil-water automatic metering system and measuring method thereof

Abstract

The invention discloses an online trace oil-water automatic metering system and a measuring method thereof. The system comprises an oil-water separation tube, a drain tube, a liquid inlet tube, a organic glass plate, a total liquid metering device, a flat panel light source, and a digital camera. By calibrating and calculating the volume factor, the digital camera dynamically recognizes the oil and gas interface and the oil-water interface in real time, and calculates the dynamic oil and water volume by measuring the total liquid discharge amount in real time. The invention has simple structure and small volume, and greatly reduces the volume of the core outlet to the identifiable area of the measuring tube -that is, the dead volume; The system can be directly connected to the core outlet,inheriting all the benefits of manual metering, and because of its small size, it can be placed directly in the incubator where the core holder is located, avoiding the thermostat that is separatelyprovided for the metering device, and also reduces the volume.

Description

technical field [0001] The invention specifically relates to an online trace oil-water automatic metering system and a metering method thereof. Background technique [0002] Core displacement experiments in scientific research laboratories in the field of petroleum and geological research require micro-quantity and accurate online oil-water metering. For a long time, the metering has been collecting the output fluid at the outlet of the core with glass tubes, manually observing the amount of oil and water, and reading the glass manually. In recent years, some automatic measuring instruments have appeared on the market, but the accuracy, ease of use, and precision cannot be solved well, and the operation is inconvenient. Users finally believe in manual measurement. The dead volume of the automatic metering device is large, which causes the metering lag, which brings great troubles to the influence of the experimental results and data analysis.
