Multi-phase flow monitor

Abstract

The invention discloses a multi-phase flow monitor comprising a flow sensor group, an oil-water proportion sensor set and a temperature sensor group. The multi-phase flow monitor is characterized in that the flow sensor set is composed of multiple oil-water mixed liquor flow meters, an alternating current electromotive force, exerted on media in the tube, of an alternating magnetic field with a specific frequency is used for measuring flow speed, the total fluid flow can be precisely measured in combination with the pipeline diameter, and the oil-water proportion sensor set is composed of multiple oil-water proportion detection sensors. Electrode sets of the multiple oil-water proportion sensor which are distributed in the circumference direction of the tube are evenly distributed on the outer side of the tube wall, all material compositions in the media in the tube and specific loss relations of all materials in the media are used for measuring the proportion of the content of all the materials in the media, and finally needed precise values of all physical quantities are obtained. The temperature sensor set is composed of multiple cylindrical platinum resistor temperature sensors, temperature correction parameters are provided, and finally precise values of all physical quantities are obtained. The multi-phase flow monitor is provided with a short message module and therefore can monitor oil well data at any time.

Description

technical field [0001] The multiphase flow monitor related to the invention belongs to the field of energy, and is especially suitable for the multiphase flow monitor used in oil production oil well single well oil measurement and related applications. Background technique [0002] At present, it is more and more difficult to exploit oilfields. Previously, deep wells and heavy oil wells were not exploited. Now, due to the depletion of resources, deep wells and heavy oil wells are constantly being exploited, and workers are required to go to the wells for sampling, testing, and collection every day during oil extraction operations. , summarization and other cumbersome processes, and greatly improved the production efficiency and data accuracy, the change of the oil well cannot be grasped in time, the content of the oil and water well and the remote data transmission cannot be accurately measured, which brings problems to the oil well mining operation. Huge difficulty. Conte...
