Description

With stove steam flue gas mixed water injection oil recovery by heating device

One, technical field:

The utility model belongs to petroleum equipment and oil production technology, specifically a kind of same stove steam flue gas mixed water injection oil recovery by heating device.

Two, background technology:

For excavating and improving thick, sticky, Residual oil oil well or oil field oil production and produce oil efficiency, in oil reservoir, inject high temperature, high steam to strengthen the mode of crude oil activity, the occupancy displacement crude oil of high pressure injecting carbon dioxide, nitrogen and washing oil mode, be all one of conventional means of taking under prior art, that these means and mode all possess skills is ripe, reliable for effect, to the remarkable advantage such as underground environmental pollution is slight.But also there is many obvious deficiencies and defect: 1, produce steam and realize by consuming ore fuel, its process produces a large amount of high-temperature flue gas, wastes energy and impurely goes up environment.2, injecting carbon dioxide or nitrogen need to buy and transport more, take more financial and manpower resources and equipment resource, and cost of production is high.3, produce the boiler smoke palpus governance for reaching standard discharge of steam, same need investment cost, in sum, the application of these modes exists when exploiting new forms of energy and consumes the useless energy that has, and is to protect environment on the ground to manufacture trouble in the time of protection underground environment.

Three, summary of the invention:

The purpose of this utility model is for above deficiency and defect, provides a kind of technology maturation, environment-friendly high-efficiency, that with low cost, cost performance is higher is energy-conservation, reduce discharging, the same stove steam flue gas mixed water injection oil recovery by heating device of volume increase.

A same stove steam flue gas mixed water injection oil recovery by heating device, it comprises injection boiler, water inlet pipe, steam pipe, flue, smoke eliminator, high-pressure hydraulic pump, return pipe, water pump, fume pipe, air-introduced machine, flow divider, smoke vent opening, flue gas compressor, mixture pipe and oil well, is characterized in that flow divider being installed and being connected smoke eliminator on the flue of injection boiler, and smoke eliminator is the sealing chamber that heat insulating material is constructed, and in chamber, by partition, is divided into water curtain ground, settling tank and purifying pond three parts, waterfall booth is completely separated with the partition top between settling tank, sluice is left in bottom, partition between settling tank and purifying pond is overfall, top arranges filtration membrane, in waterfall booth, by return pipe and demineralized water spray, form water curtain, on waterfall booth end wall, fume pipe is set, fume pipe near-end arranges air-introduced machine, close on oil well place flue gas compressor is set, and be incorporated to steam pipe by flow divider, purifying pond both sides set out the mouth of a river, one side delivery port connects return pipe by water pump and enters waterfall booth, and opposite side delivery port enters boiler heating pipe by high-pressure hydraulic pump.

Its technical method process is flue gas that injection boiler produces after smoke eliminator is processed, and by the flue gas compressor remittance steam pipe that pressurize, by mixture pipe, together injects oil well; Softened water for boiler enters smoke eliminator with water curtain sprinkling form, after the flue gas of washing boiler flue input, after settling tank and filtration membrane processing, enter clear water reservoir, a part supplies water to injection boiler through high-pressure hydraulic pump, and a part imports demineralized water washing pot kiln gas again through water pump and return pipe; Its smoke eliminator is the closed chamber that heat preserving and insulating material is constructed; Its injection boiler flue is installed respectively flow divider with the fume pipe node of supply flue gas device and fume pipe and the smoke vent opening tubercle after smoke eliminator processing.

Intermittent mixture pipe and the oil well of injecting of flue gas after described smoke eliminator is processed.

Described injection boiler flue gas can inject separately the oil well displacement of reservoir oil after smoke eliminator is disposed, and also can discharge through smoke vent opening.

Described to oil well, inject and take boiler smoke when main, in smoke eliminator, add oxygen scavenger deacidification in a small amount.

Same stove steam flue gas mixed water injection oil recovery by heating device of the present utility model compared with prior art, has application technology maturation, and apparatus structure is simple, field conduct, and energy-conserving and environment-protective, increase production the distinguishing features such as efficient, also have in addition following outstanding advantages:

1, the closed smoke eliminator of constructing with heat preserving and insulating material, by spray water curtain mode purification boiler flue gas with softened water for boiler and reflux cycle water, when purifying smoke is up to standard, reduced on the one hand the temperature of flue gas, be convenient to flue gas compressor safety, run well efficiently, take full advantage of on the other hand a large amount of high-temperature residual heats of flue gas, heat to boiler water supply preheating, reduce vapour energy consumption processed.

2, with stove steam flue gas mixed water injection, the one, by the flue gas that contains great amount of carbon dioxide bury be fixed in underground, alleviate or avoid the pollution of carbon emission to atmospheric environment, the 2nd, can give full play to the comprehensive advantage that oil recovery by heating and occupy-place displacement are recovered the oil, improve output, increase back production, the completeness of second mining, resource utilization is higher, the 3rd, the producing and applying of steam, the purification of flue gas and application, same stove together, need not purchase and transport, cost is lower, the 4th, the steam of producing and produce the flue gas that steam produces and all utilized, utilize resource more abundant, more approach the environmental protection concept of " eating dry bleeding ".

3, noting flue gas extracting device of oil and method is abroad to inject pure flue gas, and not with steam blending, thereby flue gas will carry out separately purified treatment.Take independent etching process and the oil well material of preventing.With the meta-alkalescence high steam blending of acid flue gas and injection boiler output, can effectively reduce corrosion rate, guarantee the life-span corrosion of oil well, when more for the less and flue gas of steam injection amount, can in clean room, add a small amount of alkali (NaOH) to neutralize or add a small amount of oxygen scavenger neutralization.

Thereby the utlity model has good application value.
