Measurement flowmeter of crude oil single well

Abstract

The invention discloses a measurement flowmeter of a crude oil single well. The flowmeter comprises a shell body, wherein the shell body comprises an inner layer shell body and an outer layer shell body; heat preservation cotton is disposed between the inner layer shell body and the outer layer shell body, and an explosion-proof tank is disposed on the outer layer shell body; and a flow measurement module, a density measurement module and a temperature measurement module are disposed in the shell body. The flowmeter disclosed by the invention has the advantages that advanced heating and temperature measurement technologies are adopted; efficient heat conduction design is used; and thus the whole measurement system has an exquisite structure and high energy efficiency. A flow measurement component is resistant to blocking and wear, so that media which can hardly be measured by a traditional flowmeter can be measured; the service life is long; maintenance is unnecessary; on-site labor intensity of workers is reduced; safety of production operations is increased; oil well measurement accuracy is increased; the use cost for oil well measurement instruments is reduced; and oil well measurement efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of petroleum metering equipment, and relates to a metering flowmeter, in particular to a crude oil single well metering flowmeter. Background technique [0002] At present, with the development of measurement and control technology, especially the fine management of the petroleum industry, the requirements for the oil well production metering system are getting higher and higher; the traditional crude oil single well metering flowmeter has a single design function, and its measurement accuracy is low due to the complex composition of the oil well production medium , Impurities in the medium or low-temperature condensate lead to a large amount of on-site maintenance of the equipment, and the single signal processing leads to low automatic processing capabilities, which require continuous calibration, and are increasingly unable to meet the requirements of modern metrology.
