Abstract
The utility model relates to a mixed gas injection device for petroleum thermal recovery, which comprises a combustor, a housing, an inner housing, a subsonic effuser and a steel cylinder. Particularly, the bottom of an oil inlet spigot joint on the combustor is provided with a swirler, and the cavity of the bottom of an air inlet spigot joint is inclined inward. The exterior margin of the inner housing is provided with a liquid collecting cavity which is communicated with a mixing chamber through an inclined hole, and thus the cooling water can be directly vaporized after encountering the high temperature mixed gas in the mixing chamber. The utility model is mainly used for petroleum thermal recovery, and uses crude petroleum as fuel. The utility model which has only one set of main water system has low operating cost and convenient move, and has wide application prospects in petroleum thermal recovery.
Description
Technical field
The present invention relates to a kind of oil exploitation device, especially a kind of petroleum thermal recovery device.
Background technology
The conventional means of petroleum thermal recovery is to utilize high pressure steam boiler to inject steam to oil reservoir.This method has that heat waste is big, energy consumption is high, equipment cost is high, to defectives such as atmosphere pollution are serious, and the exploitation later stage is because oil reservoir ponding too much makes recovery ratio seriously descend.
In recent years, states such as the U.S. and Canada are attempting and development adds the new technology of on-condensible gas to the fluid that injects oil reservoir during at petroleum thermal recovery, and have obtained good effect, and particularly during heavy crude heat extraction, test has proved that this is an obvious results new technology.Therefore, seek a kind of high enthalpy water vapour that can produce and to produce on-condensible gas nitrogen (N again with large volume
2Thereby) can also produce and crude oil is had the viscosity reduction effect increase its mobile carbon dioxide (CO
2) device of gas is used for thermal recovery and just becomes a very urgent and very important task.
The patent No. is that the utility model patent of 98239070.X discloses a kind of composite gas gas injection device, and this device can produce the mist that contains water vapour, nitrogen and carbon dioxide.But being to use this device can only be fuel with diesel oil, and its burning is insufficient, and this mainly is because at the burner place, empty G﹠O undercompounding.This device need be equipped with two cover flood patterns in addition, makes it comparatively too fat to move, moves inconvenience.
Summary of the invention
It is fuel and the petroleum thermal recovery mixed gas injecting device that only needs a cover flood pattern with crude oil that the purpose of this utility model is to disclose a kind of.
The technical solution of the utility model is as follows: a kind of petroleum thermal recovery mixed gas injecting device, it comprises burner, shell, inner casing, subsonic effuser and steel cylinder, be followed successively by combustion chamber and blending chamber below the burner, on burner, there is air intake to connect mouth, former oil-in connects mouth and spark plug, there is a water inlet to connect mouth in the shell upper end, communicate with the spiral tank of inner casing outer rim, subsonic effuser is between shell and steel cylinder, one speed reducer is arranged in steel cylinder, especially: meet gonys portion in former oil-in and be equipped with swirler, air intake connects the gonys cavities and slopes inwardly, and its axis and former oil-in connect the axis angulation of mouth.At spiral tank end a liquid collecting cavity is arranged in addition, its bottom is mixed the chamber by inclined hole uniform on the inner casing and ginseng and is communicated, and portion, inner casing end have a short tube in the enclosure, between short tube and the inner casing sealing ring are arranged.
This device is fuel with crude oil, greatly reduces use cost; Crude oil fully burns, and the water in the helicla flute enters the blending chamber, when making full use of raw material, has also saved a cover flood pattern.
Description of drawings
Accompanying drawing is the structural representation of this gas injection device, 1-burner among the figure, 2-shell, 3-inner casing, the 4-subsonic effuser, the 5-steel cylinder, the 6-oil-in connects mouth, and the 7-air intake connects mouth, the 8-spark plug, the 9-swirler, the 10-water inlet connects mouth, 11-spiral tank, 12-liquid collecting cavity, 13-inclined hole, the short tube of 14-, 15-reducer, 16-combustion chamber, 17-blending chamber, 18-gas injection port, 19-sealing ring.
The specific embodiment
The utility model is described in further detail for the contrast accompanying drawing below.
This device comprises burner 1, shell 2, inner casing 3, subsonic effuser 4 and steel cylinder 5, on burner 1, there is the oil-in to connect mouth 6, air intake connects mouth 7 and spark plug 8, there is a water inlet to connect mouth 10 in the upper end of shell 2, communicate with the spiral tank 11 on the inner casing outer rim, subsonic effuser 4 is between shell 2 and steel cylinder 5, one speed reducer 16 is arranged in steel cylinder 5, a swirler 9 is arranged at the bottom that especially connects mouth 6 in the oil-in, the bottom cavity that air intake connects mouth 7 slopes inwardly, its axis and former oil-in connect the axis angulation of mouth 6, and crude oil and air are fully mixed; Spiral tank 11 ends on inner casing 3 outer rims are liquid collecting cavity 12, and it mixes chamber 17 by inclined hole 13 on inner casing 3 inwalls and ginseng and communicates, and so just make cooling water directly and the high temperature and high pressure gas vaporization of meeting, thereby need not be more specially to 17 water fillings of blending chamber; Shell 2 inside, inner casing 3 ends have a short tube 14, between inner casing 3 and the short tube 14 sealing ring 19 are arranged, and can prevent the leakage of sealing like this.Package unit all can adopt stainless steel.
During work, the crude oil of preheating connects mouth 6 and flows into from the oil-in, and compressed air connects mouth 7 from air intake and enters.Crude oil connects mouth 6 bottoms in the oil-in because the centrifugal action of swirler 9 forms hollow cone from the ejection of direct current spout, meet with the high pressure draught of numerous direct current spout ejections from air intake 7, with the best angle bump, under the gentle dynamic action of centrifugal force, fully mix, atomize and light mutually by spark plug 8.
Crude oil burns in combustion chamber 16 and generates 2000 ℃ nitrogen and carbon dioxide gas mixture.In order to guarantee that combustion chamber 16 continues trouble free service under HTHP, meet mouth 10 places at water inlet and inject cooling water.Cooling water flows through from spiral tank 11, carries out interchange of heat after liquid collecting cavity 12 and inclined hole 13 enter into blending chamber 17 by the gas in inner casing 3 inwalls and the combustion chamber 16, and meets with the HTHP mist that enters into blending chamber 17.Water heat absorption vaporization rapidly, simultaneously former mist cooling.So, formed the mist that meets 250～350 ℃ nitrogen, carbon dioxide and steam that oil production technology requires in blending chamber 17.With the shell 2 terminal subsonic effusers 4 that link to each other, can guarantee that combustion chamber 16 is in the low-pressure duty when the well voltage rise is high.Reducer 16 in the steel cylinder 5 makes mixed airflow slow down and further homogenising.Last steam, nitrogen, the carbon dioxide gas mixture that satisfies the oil production technology requirement fully injects oil reservoirs by gas injection port 18.
