Description
Technical field
The present invention relates to the field mining equipment technical field, be specifically related to a kind of gas-liquid two-phase flow instrument.
Background technology
The metering of polyphasic flow is a major issue in oil field always, and along with the development of oilfield exploitation technology, this problem is more and more important.Traditional solution is to build a large amount of test satellite locations in oilfield surface engineering, approximately per tens mouthfuls of wells need be built a test satellite location, every mouthful of well is laid the pipeline that leads to test satellite location, on test satellite location, utilize separating tank that the tolerance and the liquid measure of oil well are measured, every mouthful of well measured 1 to 2 hours, and conversion is whole day output again.This method cost height, operation are also inconvenient.
At present in oilfield process, the oil well less to the production fluid amount (between 0.5 to 15 meter between 3/ day) lacks measurement means.The existing patented product that utilizes volume pipe to measure low consumption of the liquid is measured because gas-liquid enters volume pipe simultaneously, and is inapplicable for the oil well that gas production rate is bigger.
Summary of the invention
The invention provides a kind of small liquid volume gas-liquid two-phase flowmeter, in order to solving in the casing-head gas liquid two-phase amount, liquid measure hour, the problem that measuring error is big.The present invention is easy to operate, and use cost is low, and simple in structure, and product price is low, simultaneously the measuring accuracy height.
For solving the problem that prior art exists, technical scheme provided by the present invention is: a kind of small liquid volume gas-liquid two-phase flowmeter, comprise electric four-way valve, volume pipe, the electro-induction proximity transducer, also comprise gas fractionation unit, reverse stabilising arrangement, temperature sensor, pressure transducer and precession vortex flowmeter, it is characterized in that described vertically disposed gas fractionation unit links to each other with inlet pipeline, its upper port links to each other with outlet conduit by pipeline, pipeline is provided with temperature sensor, pressure transducer and precession vortex flowmeter, the lower port of gas fractionation unit connects the inlet of electric four-way valve by pipeline, the outlet of electric four-way valve links to each other by pipeline with vertically disposed reverse stabilising arrangement lower end, oppositely the stabilising arrangement upper port links to each other with outlet conduit by pipeline, electric four-way valve two mouthfuls of two access ports that connect horizontally disposed volume pipe by pipeline in addition except that the gateway.
Be provided with piston and electro-induction proximity transducer in the described volume pipe; Volume pipe has the pipeline of pipeline UNICOM gas fractionation unit upper port near place, two ends, the left and right sides; Piston total body density in the volume pipe is 860～1000 kilograms/meter
3The seal of piston is the punching rubber tube.
Compared with prior art, advantage of the present invention is:
1. use cost is low: used sensor still less during design, reduced the instrument that needs periodic calibrating, greatly facilitated the user, easy to operate, use cost is low.
2. measuring accuracy height: owing to adopted the volume pipe principle to measure liquid measure, the gas in the detected fluid enters volume pipe again after gas fractionation unit separates, improved precision greatly.

Fig. 2 is a volume pipe structural representation of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes electric four-way valve 2 (or valve group of alternative four-way valve function), volume pipe 3, electro-induction proximity transducer 10, also comprise gas fractionation unit 1, reverse stabilising arrangement 7, temperature sensor 4, pressure transducer 5 and precession vortex flowmeter 6, described vertically disposed gas fractionation unit 1 links to each other with inlet pipeline, its upper port links to each other with outlet conduit by pipeline, pipeline is provided with temperature sensor 4, pressure transducer 5 and precession vortex flowmeter 6, the lower port of gas fractionation unit 1 connects the inlet of electric four-way valve 2 by pipeline, the outlet of electric four-way valve 2 links to each other by pipeline with vertically disposed reverse stabilising arrangement 7 lower ends, oppositely stabilising arrangement 7 upper port link to each other with outlet conduit by pipeline, electric four-way valve 2 two mouthfuls of two access ports that connect horizontally disposed volume pipe 3 by pipeline in addition except that the gateway.
Be provided with piston 8 and electro-induction proximity transducer 10 in the described volume pipe 3; Volume pipe 3 has the pipeline of pipeline UNICOM gas fractionation unit 1 upper port near place, two ends, the left and right sides; Piston 8 in the volume pipe 3 is made for multiple material is compound, and total body density is 860～1000 kilograms/meter between water and oil
3The seal of piston 8 adopts rubber tube to guarantee that resistance is enough little; Rubber tube is the punching rubber tube in order to keep the internal and external pressure balance under the different pressures.
The course of work of the present invention is: fluid is earlier through popular collating unit, gas is told, gas is measured through the precession vortex flowmeter, liquid enters volume pipe by four-way valve, promoting piston holds to the A end motion from B, when arriving volume pipe A end, trigger the electro-induction proximity transducer, trigger the electro-induction proximity transducer and signal to the four-way valve electric actuator, carry out pressure control valve, volume pipe gateway transposing behind the pressure control valve, liquid continues to promote piston and holds to the B end motion from A, after arriving the B end, finish a working cycle (comprising two strokes).In this circulation, it is total to record fluid flow Q again
Q is total=A
0* L * 2
A
0Long-pending for the volume pipe intracavity section, L is the effective movable length of piston in the interior stroke of volume pipe.
Before liquid enters volume pipe, in gas fractionation unit, carried out gas-liquid separation; After liquid leaves volume pipe, enter outlet conduit before, also oppositely experiencing stable process in the stabilising arrangement, the liquid that accumulates in stabilising arrangement provides certain resistance, can guarantee under design conditions that gas can not pass through the liquid road; Specially designed volume pipe has guaranteed that the resistance to flow on liquid road is enough little simultaneously, and liquid that can not enters gas circuit; Electric four-way valve (or valve group of alternative four-way valve function) can be implemented in the pressure control valve process, can not make the above channel connection of two-way simultaneously.
