Description
Technical field
The utility model belongs to technical field of petroleum extraction, relates to the mensuration of oil well associated gas gas production rate.
Background technology
When oil well production, crude oil extraction ground, pressure decreased, the associated gas being dissolved in crude oil also can be escaped.Can calculate produced GOR by measuring gas production rate and oil offtake, produced GOR is one of important indicator of field produces.
The size of gas flow generally adopts gas meter metering.Gas meter is of a great variety, is widely used in commercial production, energy measurement, communications and transportation, environmental engineering, scientific experiment.Most orifice plate, electromagnetism, turbine, metallic rotameter measuring accuracy, intelligent degree are all higher, but owing to depending on fluid flow state, so have strict demand for mounting means, import and export flow development length, insertion depth, some gas meters also there are certain requirements tested gas clarity, and the above-mentioned type flowmeter price is generally comparatively expensive.
For some oil field, production line natural conditions are comparatively severe, and shaft collar is original simple, do not possess the condition of installing gas flowmeter; Some oil fields low yield, economic benefit is poor, and expensive flowmeter is installed in inconvenience investment; Some associated gas output is lower or even micro-, and numerical value, outside flowmeter range, cannot be measured.
Summary of the invention
The utility model aims to provide a kind of oil well associated gas measuring device for gas simple in structure, easy to use.
Oil well associated gas measuring device for gas described in the utility model, comprises associated gas collection tube, liquid tank and gas bottle, and wherein gas bottle is inverted in liquid tank, and bottleneck is fixed on bottom land and is communicated with liquid tank, and associated gas collection tube is passed into gas bottle bottom.
Preferably, associated gas collection tube is connected in sequence by rubber bush, flexible pipe, wireway, and rubber bush one end is opening end, the other end is endpiece, endpiece connecting hose, flexible pipe is connected with L-type wireway again, and the endpiece of wireway is passed into gas bottle bottom.
More preferably, also comprise base, described liquid tank is fixed on base, is also provided with base horizontal adjusting device, horizontal display apparatus, ambient temperature measuring device, air pressure measuring apparatus on base.
The utlity model has following advantage:
1, connect or welding without flange, can be connected on the caliber of any size, to the no requirement (NR) of pipeline flow development length;
2, installing each main element is glass material, does not have etching problem.Measured medium can be any pure gas or mixed gas that does not react (being slightly soluble in water) with water;
3, applicable flow range is wide in range, is particularly suitable for low flow velocity low discharge situation, and computing method are simple and quick;
4, simple in structure, portable removable.

Embodiment
Embodiment mono-
As shown in the figure, oil well associated gas measuring device for gas of the present utility model, comprises rubber bush 4, flexible pipe 5, and L-type wireway 6, tank 7 and gas bottle 8, wherein gas bottle 8 is inverted in tank 7, and its bottleneck is plugged with rubber plug 9, on rubber plug 9, has perforate.Rubber bush 4 one end are opening end, are connected with well mouth oil pipe outlet 2 or oil jacket annular space outlet 3; The other end is endpiece, and this endpiece is connected with wireway 6 by flexible pipe 5, and endpiece is provided with needle valve.The other end of wireway 6 extend into the bottom of gas bottle 8 through gas bottle rubber plug 9.
Tank 7 is fixed on plinth 12, and draining valve 10 is left in tank 7 bottoms, discharges water and flows into water-holding cup 11, and water-holding cup 11 is also fixed on base 12.
In base 12 planes, be provided with thermometer 13, horizontal display instrument 14, barometer 15.12 4 jiaos of bases are provided with four Level tune nuts.
When the utility model uses,
1, connect above-mentioned parts, close the needle valve of rubber bush 4 endpiece, the horizontal nut of adjusting makes base 12 in horizontality;
2, in tank 7, add water, water level did not have gas bottle 8.In gas bottle 8, be full of water, open draining valve 10, water level progressively declines, and is down to concordantly with bottle stopper, closes draining valve 10;
3, open rubber bush outlet needle valve, draining gas collection, manual time-keeping simultaneously.Associated gas enters in inverted gas bottle 8 by rubber bush 4, flexible pipe 5 and L-type wireway 6, and gas progressively occupies the space of gas bottle 8, and gas pressure and Action of Gravity Field make water be discharged from by the perforate on rubber plug 9, in final gas bottle 8, is full of associated gas.Repetitive operation, records each gas collection time;
4, associated gas air volume calculation
