Embodiment Construction

[0029] In order to further disclose the technical solutions of the present invention, the following will be described in detail through examples in conjunction with the accompanying drawings of the description;

[0030] The invention relates to a multi-phase flow meter product that uses a new principle and method for high-precision, on-line continuous quantitative measurement. ), front tank (1), open channel inclined measuring tube (19), rear tank (15), gas differential pressure sensor (12), liquid level differential pressure sensor (9, 10, 11), pressure sensor (16), A temperature sensor (14) and a gas-liquid outlet (13) are formed. After the gas-liquid inlet, there is a cylindrical gas-liquid pre-separator cyclone (2). After the gas-liquid mixed flow is separated by the gas-liquid pre-separator (2), the gas flows from the top of the front tank through the pipeline at the upper end of the separator. Part of the gas flows into the rear tank through the gas bypass pipeline (17)...

Abstract

This invention relates to one oil and water mixture meter device, which comprises front and back tar, pre-division rotation device, clear inclination test tube, gas micro difference sensor, liquid difference sensor, pressure sensor, temperature sensor and gas and liquid exit hole, wherein, the gas side tube is connected with front and back tar and clear inclination measurement tube by 1.5 degree; setting three liquid difference voltage sensor in between and one gas difference sensor and setting two difference sensors between middle and down parts of tar; setting pressure sensor and temperature sensor in back tar to take gas and liquid threshold height and lift, and pressure impulse signals to get difference signal continual time process and each character value.

Description

1. Technical field [0001] The invention relates to a phase-separation continuous metering device for oil-gas-water mixed flow of an oilfield output medium, which is suitable for measuring the flow rates of mixed multiphase flows of oil, gas and water. 2. Background technology [0002] Multiphase continuous metering of oil well produced fluid is an urgent problem to be solved in oilfield production. In recent years, the development focus of the international oil industry has gradually shifted to deserts and seas. The new development of unmanned desert metering stations and offshore satellite platforms requires new metering technologies that meet the technical and economical requirements. Especially in offshore oil development, due to the limitation of platform area, construction cost, construction difficulty and other factors, the traditional oil well metering method can no longer meet the production needs. However, with the development of multiphase mixed transportation te...
