Description
Technical field
The utility model relates to the density of measuring fluid and the device of 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
Passing through oil well produced crude oil at the bottom of ground, is the potpourri that materials such as 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, promptly, adopt knockout drum, rely on the different specific weight of gas and liquid (oil water mixture), gas is separated with liquid, with artificial method metering gas, liquid measure, the water percentage of liquid adopts the method for hand sampling chemical examination to obtain then.The shortcoming of this human metering method 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, inaccurate, particularly under the unsettled situation of Oil, Water, Gas output in oil well, the numerical value that adopts manual method to measure tends to occur bigger deviation, can not reflect the actual conditions of oil well production.
Summary of the invention
The purpose of this utility model provides the device of each component situation in a kind of on-line automatic measurement crude oil.
The utility model is achieved in that
The utility model mainly is made up of VERTICAL TUBE, horizontal tube, pair pipe, differential pressure measurement instrument, pressure transducer, temperature sensor, signal processing system.The pipeline of VERTICAL TUBE, horizontal tube, Fu Guanwei series connection, VERTICAL TUBE and horizontal tube are 90 ° ± 10 ° angles, and the pressure point that the differential pressure measurement instrument is installed on horizontal tube and the VERTICAL TUBE respectively has two, and the spacing of per two pressure points is greater than 200mm.Temperature sensor, pressure transducer are installed on the pipeline.
During the utility model work, when fluid was mobile from VERTICAL TUBE, horizontal tube and Fu Guanzhong, differential pressure measurement instrument, temperature sensor, pressure transducer can be gathered differential pressure signal, temperature signal and the pressure signal that is produced when fluid flows respectively.These signals are the entering signal disposal system thereupon.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, so signal processing system just can provide the hybrid density of fluid-mixing and the containing ratio of each constituent element.
This device can be used for the on-line determination to the hybrid density of oil field produced crude oil and oil thereof, water, rock gas amount, 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 adapted at using under any operating mode.

Embodiment
Narrate two embodiment below in conjunction with accompanying drawing:
The measurement mechanism of the oil density of 1, one forward flow of embodiment and oil, liquid water content.
As Fig. 1, shown in Figure 3.This device becomes pipeline by VERTICAL TUBE 1, horizontal tube 2,6 series connection of pair pipe, and fluid is mobile along the direction of paying pipe → horizontal tube → VERTICAL TUBE.Paying pipe 6 length is 300mm, and internal diameter is 32mm, and the length of horizontal tube, VERTICAL TUBE is 800mm, and internal diameter is 32mm.Differential pressure measurement instrument 3 is being separately installed with two groups of pressure points on the horizontal tube He on the VERTICAL TUBE, i.e. A1, A2 pressure point and B1, B2 pressure point, between A1, the A2 and the distance between B1, the B2 be 400mm; Pressure transducer 4 and temperature sensor 5 are installed in to be paid on the pipe 6; Signal processing system 7 adopts the A/D interpreter.
The measurement mechanism of the oil density of 2, one reversed flow of embodiment and oil, liquid water content.
As Fig. 2, shown in Figure 3.The structure of this measurement mechanism and the foregoing description 1 are basic identical, and difference only is that the flow direction of liquid in tandem tube is opposite, and promptly flow direction is: VERTICAL TUBE → horizontal tube → pay and manage.
