Abstract
The utility model discloses a fire-flooding extraction hydrogen sulfide removing device for a heavy oil well, comprising a sealed container, wherein a drug feeding port and a gas outlet port are arranged on the sealed container; a gas inlet pipeline is arranged in the sealed container; one end of the gas inlet pipeline extends to the sealed container so as to form a gas inlet port; and a plurality of sand heads are further arranged on the gas inlet pipeline. The fire-flooding extraction hydrogen sulfide removing device disclosed by the utility model has the advantages of low manufacture cost, convenience for installation, maintenance and transportation, capabilities of effectively removing a large amount of hydrogen sulfide mixed gas produced by heavy oil fire-flooding, preventing environment pollution, preventing the hydrogen sulfide from endangering lives of human bodies, livestock and wild animals, and avoiding the corrosion to oil-gas field equipment and household appliances.
Description
Technical field
The utility model relates to a kind of hydrogen sulfide removal device, particularly relates to a kind of heavy oil wells fireflood exploitation and removes the sulfuration hydrogen production device.
Background technology
In the oil field of adopting viscous crude fire flood mode, oil reservoir constantly injects air, and air and crude oil burn on the stratum, and the heating oil reservoir makes viscosity of thickened oil thinning, thereby makes the viscous crude extraction; Yet in the burning oil reservoir, also can produce a large amount of toxic and harmfuls such as hydrogen sulfide, along with the discharging of formation gas, pernicious gases such as hydrogen sulfide also are discharged in the air.
Hydrogen sulfide is a kind of dangerous gas of severe toxicity, and concentration surpasses 28mg/m in air
3The time, the people just can't work, and surpasses 1000mg/m
3The time, just can cause acute poisoning, cause casualties.The hydrogen sulfide mist that the viscous crude fire flood is discharged, the concentration of its hydrogen sulfide surpass 1000 mg/m sometimes
3These hydrogen sulfide are dispersed in the environment around the oil field, influence oil field worker and near resident's personal safety, influence life security and the crop growth of domestic animal and wild animal.Hydrogen sulfide also can make oil gas field equipment and near resident's household electrical appliances produce corrosion, and this is because the water-soluble ionization of hydrogen sulfide goes out hydrogen ion, and these hydrogen ions will make iron and steel pipeline and ironware produce the cause of liberation of hydrogen corrosion.
Because these harm of hydrogen sulfide, so must the hydrogen sulfide gas that the viscous crude fire flood produces be administered.
The utility model content
The purpose of the utility model just provides a kind ofly can effectively remove hydrogen sulfide, and heavy oil wells fireflood with low cost exploitation removes the sulfuration hydrogen production device, thereby solve the hydrogen sulfide mist directly is discharged into problem of environment pollution caused in the air.
The purpose of the utility model realizes through following technical proposals:
A kind of heavy oil wells fireflood exploitation removes the sulfuration hydrogen production device; Comprise an airtight container jar, said airtight container jar is provided with dosing mouth and exhaust opening, in the airtight container jar air inlet pipeline is set; One end of air inlet pipeline stretches out the airtight container jar and forms air inlet port, also is provided with some husky heads on the air inlet pipeline.
Further, also be provided with drain and overfall on the said airtight container jar.
Further, the air inlet pipeline upper horizontal is equipped with perforated board in the said airtight container jar, and this perforated board is the flat board that has some through holes, is used to prevent overflow from above when gas is too much.
Further, also be provided with the ball float that is used to confirm to add dose in the described airtight container jar.
Further, said air inlet pipeline is horizontally disposed " rich " font pipeline, offers some holes on it, and husky head passes this hole and is vertically mounted on the pipeline.
The beneficial effect of the utility model is: cheap for manufacturing cost; Installation, maintenance, convenient transportation; Can effectively remove a large amount of hydrogen sulfide mists that the viscous crude fireflood produces; Thereby prevent the pollution of the environment, avoid hydrogen sulfide that the life of human body, domestic animal, wild animal is worked the mischief, avoid it that oil gas field equipment and household electrical appliances are produced corrosion.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of the inside of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of heavy oil wells fireflood exploitation removes the sulfuration hydrogen production device, comprises an airtight container jar, and said airtight container tank top is provided with dosing mouth 3 and exhaust opening 4, and the middle part leans on last position that overfall 5 is set, and the bottom is provided with drain 6.Be horizontally disposed with " rich " font air inlet pipeline 8 in the airtight container jar, an end of air inlet pipeline 8 stretches out the airtight container jar and forms air inlet port 1, also offers some holes on the air inlet pipeline 8, and husky 9 is passed this hole and vertically install, and stretches into the airtight container pot bottom.Air inlet pipeline 8 upper horizontal are equipped with perforated board 2 in the said airtight container jar, and this perforated board 2 is for having the flat board of some through holes.Also be provided with the ball float 7 that is used to confirm to add dose in the airtight container jar.
In use, elder generation is connected to the air inlet port 1 usefulness flange of this device in the sleeve pipe outlet of oil well; Open dosing mouth 3 then, add liquid curing hydrogen remover, and confirm to add dose through ball float 7; Open sleeve valve, observe flow meter, the gas that makes oil well release is in air inlet port 1 ascending uniform entering airtight container jar, up to the sleeve valve complete opening; Gas gets into husky 9 through air inlet pipeline 8, and husky 9 becomes evenly small bubble to gas dispersion, thereby fully reacts with liquid curing hydrogen remover, all eliminates hydrogen sulfide clean; At last, through exhaust opening 4 nontoxic gas is entered in the atmosphere.
The replacement cycle of general liquid curing hydrogen remover is 3-6 month.Also the available gas detector detects the hydrogen sulfide removal effect at exhaust opening 4, when detecting the outlet concentration of hydrogen sulfide above 10ppm, just needs to change the hydrogen sulfide remover.
Use this device need not change original production procedure, do not influence crude oil production, poisonous hydrogen sulfide is thoroughly eliminated.And the utility model can confirm device volume and husky 9 quantity based on the content of hydrogen sulfide, thoroughly solved the murder by poisoning problem of hydrogen sulfide in a large amount of high-hydrogen sulfide mists that combustion in situ produces.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
