Oil-water flowmeter for single oil well

Abstract

The invention discloses an oil-water flowmeter for a single oil well. The oil-water flowmeter for the single oil well is structured such that a bypass inlet pipeline is connected from a feeding pipe of a main pipeline of an oil field, the inlet end of the bypass inlet pipeline is connected to a bypass inlet valve while the other end is bifurcated into two branch pipes, one is connected to a watercontent measuring tank and the other is a bypass pipeline, the outlet of a bypass short pipe VII and an outlet short pipe VI of the water content measuring tank converge and then enter into an oil-gasseparating tank, after oil and gas are separated, and gas measured by a gas flowmeter through a short pipe I converges into a discharge pipe of the main pipeline to be connected to the main pipelineof an oil field system. The oil-water flowmeter for the single oil well can measure oil and water precisely of the single oil well by online measurement. The oil-water flowmeter for the single oil well is simple in structure, accurate to measure, safe and reliable and convenient to maintain, and can meet measurement of oil and water content of the oil well.

Description

technical field [0001] The invention belongs to the field of oilfield measurement equipment, and in particular relates to an oil-water flowmeter for a single oil well. Background technique [0002] In the process of crude oil extraction, the ratio of oil and water reflects the characteristics of oilfield reservoirs. It is an important basis for formulating and adjusting production plans and optimizing production parameters. It is of great significance for extending the life of oil and gas wells and improving recovery. In the actual production process of the oil field, there are many types of multiphase flowmeters for gas, oil, and water, and there are many related patents; the invention patent application with the application number 201711178453.3 published in the Chinese patent literature database is an online crude oil water-containing flow meter for oil production wells. The constant cross-section static measuring instrument is used to measure the oil-water flow of crude ...
