Problems solved by technology

As far as the two-phase separation density method currently used in various domestic oil fields is concerned, the measurement accuracy is greatly affected by the incomplete gas separation in the liquid phase. The time, its liquid and gas output are different, and even fluctuate greatly, so it often cannot achieve the expected effect

Abstract

A content analyzing apparatus is provided. A heat-insulating layer is arranged on an inner cavity wall of a straight tube housing with two opened ends; the upper wall of the housing is provided with two separated temperature sensors; a front temperature sensor is arranged on the front part of the housing and a back temperature sensor is arranged on the back part of the housing; the lower wall of the housing is provided with a heating element; the heating element is arranged between the front temperature sensor and the back temperature sensor; the internal diameter of the straight tube housing is D; the distance between the front temperature sensor and the heating element is indicated as t1, which is 0.5 to 5 times of the internal diameter D; and the distance between the back temperature sensor and the heating element is displayed as t2, which is 10 to 30 times of the internal diameter D. During the use, the content analyzing apparatus can be cooperated with a flow meter and can be applied to detection for content of multi-phase flow of oil wells and fields and to two-phase mixture metering of other industries; the content analyzing apparatus is a straight tube section, thereby having small pressure loss, so flow regime cannot be broken and the content analyzing apparatus can be conveniently installed; and the measuring and calculation values acquired by the analyzing apparatus is free of effects of pressure, so high precision is possessed.

Description

technical field [0001] The invention is a two-phase mixture content analysis device, which can be applied to the detection of multi-phase flow content of oil wells in oil fields, and can also be applied to the detection of two-phase content measurement in related industries. Background technique [0002] Oil-gas-water three-phase metering is an important task in oilfield production management. Accurate metering has important guiding significance for oil wells to grasp reservoir conditions and formulate production plans. As far as the two-phase separation density method currently used in various domestic oil fields is concerned, the measurement accuracy is greatly affected by the incomplete gas separation in the liquid phase. Time, its liquid and gas outlet conditions are all different, and even fluctuate greatly, so it often cannot achieve the desired effect. Contents of the invention [0003] The invention provides a novel two-phase mixture content analysis device. [0...
