Abstract
The invention relates to an oil-well waste gas recovery device which comprises a prizing block, a hoop, a filter, a gas collecting bladder, a safety valve, a natural gas compressor, a gas flow meter and a quick joint. The oil-well waste gas recovery device is characterized in that an inlet of the gas collecting bladder is connected with an outlet of the filter by a high-pressure hose, an inlet of the filter is connected with an outlet of a sleeve pipe by a control valve and the hoop or a flange, an outlet of the gas collecting bladder is connected with an inlet of the natural gas compressor by a connecting pipeline, an outlet of the natural gas compressor is connected with the gas flow meter, an outlet of the gas flow meter is connected with the quick joint, and the safety valve is arranged on the pipeline which is used for connecting the gas collecting bladder and the natural gas compressor. The oil-well waste gas recovery device has simple structure and strong flexibility, is portable, can flexibly recover sleeve pipe gas of various oil wells, avoids the pollution of the environment by the sleeve pipe gas and the energy wastage and recovers natural gas.
Description
One, technical field
The present invention relates to a kind of well casing gas recovery device that effluxes, specifically a kind of oil-well waste gas recovery device.
Two, background technology
Continuous exploitation along with the oil field, formation pressure descends gradually, oilbearing stratum loses the blowing ability, general all is to utilize multi-form oil pump to propose crude oil, improve liquid level in the oil well in order to reduce the oil well internal pressure, increase the submergence of oil well pump, generally the oil well casing gate is opened, the natural-gas emptying in the oil well casing in atmosphere, according to incompletely statistics, the annual oil well in the whole nation evaporate in the atmosphere with regard to the natural-gas that last billion cubic meter is arranged, the direct economic loss that causes reaches more than several hundred million yuan, this partly the serious pollution of gas environment, cause very large resource waste, therefore reclaim this part natural-gas, can energy conservation, reduce the wastage, reduce environment pollution, has remarkable economic efficiency, environmental benefit and social benefit.
Contain a large amount of methane, ethane, propane and a spot of butane, the eleventh of the twelve Earthly Branches alkane in the waste gas that oil well is discharged, these gas samplings are got up to pass through processing can produce chemical fertilizer, liquefied gas, light oil, many kinds of chemical products of flux wet goods, be important chemical material and industrial fuel, reduce the environment pollution of oily district simultaneously, purified oily district air.
Three, summary of the invention
The purpose of this invention is to provide a kind of oil-well waste gas recovery device, the outer bar casing tube gas contaminated environment that solves above-mentioned prior art existence causes the problem of energy waste.
Technical scheme of the present invention realizes in the following manner:
The present invention is by the sled piece, clip, control valve, strainer, the getter leather bag, safety valve, natural gas compressor, gas flowmeter and snap joint are formed, the import that it is characterized in that the getter leather bag links to each other with filter outlet by high-pressure hose, filter inlet links to each other with the sleeve pipe outlet with clip or flange by control valve, the outlet of getter leather bag links to each other with the natural gas compressor import by connecting line, the natural gas compressor outlet links to each other with gas flowmeter, gas flowmeter outlet links to each other with snap joint, and the getter leather bag pipeline that is connected with natural gas compressor is provided with safety valve.
Getter leather bag operating pressure is between 200-500pa, and volume is greater than 10m
3, the natural gas compressor operating pressure is greater than 5Mpa.
Oil-well waste gas recovery device can be installed on the sled piece, the parallel tubular slide rail that is welded with two symmetries in both sides before and after the sled piece bottom surface.
Simple in structure, the convenient in carrying of the present invention, mobility strong can reclaim the sleeve pipe gas of each oil well neatly, has avoided the pollution of sleeve pipe gas to environment, has reclaimed natural gas, has avoided the waste of the energy.
