Description
Technical field
The utility model relates to the device of measuring fluid density and fluid composition, is a kind of hybrid density of on-line measurement pipe laying crude oil and device of component containing ratio thereof of being used for specifically.
Technical background
The crude oil that goes out by oil mining in the ground is the potpourri that materials such as crude oil, water, rock gas are formed.People are in the production management of crude oil extraction, be sought after obtaining the complete survey data of a cover, comprise concrete data such as the hybrid density of measuring crude oil and component containing ratio thereof, this survey data, it is the important evidence of determining the oil extraction scheme, being the needs of oil field long-term stability, high yield, is reasonable development oil field, the needs that improve ultimate recovery factor.For a long time, the gage work of crude oil in China component, continue to use the method for manual metering always, its shortcoming is: need great amount of manpower and numerous and jumbled metering and assay device, and can not long-time continuous measure and on-line metering, therefore can not in time reflect the situation of change that oil well is fuel-displaced, cause measurement data imperfect, particularly under the unsettled situation of Oil, Water, Gas output in oil well, the numerical value that adopts manual method to measure tends to bigger deviation occur, is difficult to reflect the actual conditions of crude production.
Summary of the invention
The purpose of this utility model provides a kind of on-line automatic analytical equipment to each component of crude oil.The utility model is achieved in that
The utility model mainly is made up of liquid guiding tube, separating tube, horizontal tube, VERTICAL TUBE, recirculatory pipe, outlet, differential pressure measurement instrument, pressure transducer, temperature sensor, signal processing system.One end of horizontal tube, VERTICAL TUBE, separating tube is communicated with together, and the other end of horizontal tube, VERTICAL TUBE communicates with recirculatory pipe respectively.VERTICAL TUBE and horizontal tube are 90 ° ± 10 ° angles.The differential pressure measurement instrument is separately installed with two pressure points on horizontal tube and VERTICAL TUBE, the spacing of two pressure points is greater than 200mm.Temperature sensor, pressure transducer are installed on the rectangle pipeline.
During work, fluid is divided into two-way after passing liquid guiding tube, separating tube, promptly enters horizontal tube and VERTICAL TUBE respectively, discharges by recirculatory pipe and outlet at last; The differential pressure measurement instrument can collect differential pressure signal at any time by the point of the pressure on horizontal tube and the VERTICAL TUBE; The temperature sensor, the pressure transducer that are installed on the pipeline can collect temperature signal and pressure signal respectively.After these signal entering signal disposal systems, this signal processing system is carried out these signals the A/D conversion earlier, calculates function ρ=f according to fluid density then
ρ(P
1, P
2) and constituent element analytic function Φ=f
Φ(P
1, P
2) carry out analytical calculation, just can draw the hybrid density of fluid-mixing and the containing ratio of each constituent element.
This device can be used for the situations such as amount of the hybrid density of online mensuration extraction crude oil and oil thereof, water, rock gas, also can be used for the hybrid density of other fluid-mixings (as: alcohol) and the on-line metering of constituent element content thereof.This device has that volume is little, and cost is low, measures accurately and reliably, advantage such as is suitable for using under any operating mode.
