Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] Three-phase flow measurement method and device such as figure 1 As shown, the gas and liquid produced by the oil well enter the gas-liquid inlet 4 of the device, and when they flow into the measurement chamber 7 of the tank body from the measuring hole, the flow direction of the fluid enters in a tangential direction with the inner wall of the measurement chamber 7, and enters in the measurement chamber 7 Retained in the internal memory, the gas is partially separated and then gathered upwards in the upper part of the cavity through the gas measurement loop (foam metal filter 16, gas outlet 17, gas meter 18, mixer 19, gas-liquid outlet 20) through the gas meter in the loop After metering, it is discharged into the oil pipeline, and the separated liquid part sinks and accumulates in the measurement chamber 7 to produce a change in liquid level. The change in liquid le...

Abstract

The invention discloses a method and a device for measuring the productivity of an oil well. The method and device for measuring the productivity of the oil well have the advantages of good effect of separating oil and water, high measuring accuracy, simplified process, good convenience in use, and no pollution of radioactive rays, and are used for solving problems in the background technology. An electromagnetic sampling oil-water separator, a liquidometer and a traditional gas-liquid separating tank are combined as a whole body for measuring the oil and the water, wherein the gas-liquid separating tank realizes the separation of the gas and the liquid, the electromagnetic sampling oil-water separator and the measuring cavity of the gas-liquid separating tank are combined to realize the separation measuring of oil content and water content in the liquid, the liquidometer and the measuring cavity of the gas-liquid separating tank are combined to realize the measuring of the volume flow rate of an underground liquid, and the gas separated from the gas-liquid separating tank is measured by a gas meter (with temperature and pressure measuring function), thus the measuring of the oil, the gas, the water produced from the oil well is realized.

Description

technical field [0001] The invention belongs to the technical field of oil well measurement, and relates to a method and a device for measuring oil well output. Background technique [0002] At present, the measurement accuracy of three-phase flowmeters used at home and abroad is greatly affected by the oil-gas ratio, and the phase separation accuracy cannot meet the requirements of use. Many, poor reliability, large structure, expensive, and radiation pollution. Contents of the invention [0003] In order to solve the problems existing in the background technology, the method and device for measuring oil well production, a method and device for measuring oil well production with good oil-water phase separation effect, high measurement accuracy, simplified process, easy to use, and no radiation pollution are provided. [0004] The technical solution of the present invention is to combine the electromagnetic sampling oil-water phase separator and liquid level gauge with th...
