Abstract

The invention discloses a gas and liquid multiphase quantitative measuring device and a method thereof, wherein the gas and liquid multiphase quantitative measuring device comprises a gas and liquid cyclone separating tank, a quantitative measuring gear pump, a steady flow settling tank, a liquid level transducer, a pressure transducer, a temperature transducer and the like. The method mainly utilizes the cyclone separating tank to perform the primary gas and liquid separation to well mouth oil firstly, and then the oil enters the steady flow setting tank for performing the secondary gas and liquid separation and steady flow setting. The upper liquid level and the lower liquid level are controlled by utilizing the liquid level transducer while oil and water mixture is stabilized, the external-conveying measurement starts to work and reaches the set liquid level when the liquid level reaches the set high liquid level, and the measurement is finished. The purpose of measurement is achieved by repeating the operations. Because the liquid transducer, the pressure transducer, the temperature transducer and the quantitative measuring gear pump are controlled by a touch screen control system, the invention can realize the on-line monitoring for the working time of the quantitative measuring gear pump, can obtain the liquid yield according to the rated liquid discharge calculation, and has high measurement accuracy, strong operability and low cost.

Description

technical field [0001] The invention belongs to a metering device in the technical field of petroleum production, and relates to a crude oil output metering device and a method thereof, in particular to a gas-liquid multiphase quantitative metering device and a method thereof, which are suitable for crude oil metering in ultra-low permeability oil fields. Background technique [0002] The crude oil produced from the well generally contains a certain amount of water, and if the crude oil contains too much water, it will cause waste in storage and transportation, increase equipment, and consume more energy; most of the water in crude oil contains salts, which accelerates the production of equipment, containers and pipelines. Corrosion; in the oil refining process, when water and crude oil are heated together, the water will rapidly vaporize and expand, and the pressure will rise, affecting the normal operation of the refinery and product quality, and even explosion. Therefore,...
