Abstract

An embodiment of the invention provides a gas well three-phase measurement separation control system and an oil-water interface measurement method. The gas well three-phase measurement separation control system comprises a closed tank placed horizontally. The tank comprises a feed inlet, a separation chamber, an oil chamber, a water chamber and a gas outlet. The feed inlet is used for conveying materials into the tank. The separation chamber and the oil chamber are located in the tank. The oil chamber is communicated with the top of the separation chamber, and is separated from the separationchamber through a first separation plate. A first liquid level meter is arranged in the oil chamber provided with an oil outlet. The water chamber is located in the tank, and is communicated with thebottom of the separation chamber. A second liquid level meter is arranged in the water chamber provide with a water outlet. The gas outlet is arranged at the top of the tank, and is connected with a gas circuit switching control unit. The gas well three-phase measurement separation control system has the advantages that the internal structure of a container is adjusted properly, oil and water measurement chambers are added, oil-water-gas separation is realized in a separator through natural control of an oil-water interface, and accordingly, gas output, oil output and water output of a gas well are calculated.

Description

technical field [0001] The invention relates to the technical field of natural gas separation and processing, in particular to a gas well three-phase metering and separation control system and an oil-water interface metering method. Background technique [0002] In the prior art, various measurement and control schemes for measuring the liquid level of gas wells are designed for ideal working conditions. When the working conditions change, the measurement and control system will be difficult to achieve accurate measurement or cannot achieve measurement. Contents of the invention [0003] In view of the above technical problems, the embodiment of the present invention provides a gas well three-phase measurement and separation control system and an oil-water interface measurement method to solve the problem that when the working conditions of the gas well change, the measurement and control system will be difficult to achieve more accurate measurement or cannot Technical pro...
