Description

Boiler flue transformation absorbing carbon dioxide gaseous state pouring well oil production device
Technical field:
The utility model relates to a kind of corollary equipment that is used for thickened oil recovery, and particularly a kind of boiler flue isolation of purified reclaims the device of carbon dioxide pouring oil production, belongs to the thickened oil recovery technology type.
Background technology:
Along with the prolongation of oil field development time, viscous crude field, low-permeability oilfield and gas condensate reservoir oil extraction difficulty are increasing, and gas injection oil production technology technology range of application and scale constantly increase.At present, the gas injection oil production technology technology of field by using mainly contains three kinds of steam injections, carbon dioxide injection, notes nitrogen, usually contain 9%~15% carbon dioxide and 0%~85% nitrogen in the combustor flue gas such as injection boiler, and a spot of oxygen, sulfur dioxide and moisture.On the basis of original steam in jection, the oil recovery of injecting carbon dioxide and/or nitrogen is the effective way of improving the oil field development effect, improving recovery ratio in oil well.Carbon dioxide in the segregated combustion device flue gas is used for oilfield gas injection and recovers the oil, and no matter increasing crude output still aspect the minimizing environment pollution, all has great importance.Yet, because each side in the prior art, is annotated CO 2, N 2Recovering the oil also just is in the single technology stage of experimental study in advance, does not form ripe supporting technology and equipment as yet, makes the enforcement and applying of these technologies be restricted and influences.
The utility model content:
The purpose of this utility model is to provide a kind of boiler flue transformation absorbing carbon dioxide gaseous state pouring well oil production device that utilizes boiler for producing steam, the purification of flue gas absorbing carbon dioxide, the dry supercharging of tail gas are injected oil well production increasing crude oil.
The utility model is to realize like this.This kind device is made up of boiler, high-pressure hydraulic pump, compressor, washing desulfurizing tower, clean-up bed, adsorbent bed, displacement apparatus, vacuum pump, nitrogen compressor, carbon-dioxide gas compressor, blending tank, its assembling annexation is as follows: boiler, compressor, washing desulfurizing tower link to each other successively by pipeline, and high-pressure hydraulic pump links to each other with boiler; The washing desulfurizing tower is connected by the clean-up bed of pipeline with two parallel connections, and the adsorbent bed that clean-up bed is formed by the pipeline and the absorber of 5 parallel connections is connected, and adsorbent bed group top, bottom are connected with displacement apparatus with nitrogen compressor by pipeline respectively; Nitrogen compressor is connected with oil well casing by pipeline, displacement apparatus, vacuum pump, nitrogen compressor, carbon-dioxide gas compressor, continuous successively by pipeline, and with being connected with blending tank respectively from the pipeline of boiler, blending tank is connected with oil well oil conduit by pipeline.During work, this device can be by the pipeline pouring oil production by the steam of boiler for producing, flue gas is after overcompression, washing, desulfurization and drying, enter the transformation absorbing carbon dioxide and can produce 98% carbon dioxide gas, well is injected in the pressurization back, and nitrogen discharged by pressure-swing absorption apparatus and minor amounts of oxygen is injected in the oil well after the process supercharging again.Water vapour that such boiler obtains step by step and gaseous carbon dioxide, nitrogen three place's gases inject oil well by allotment, thereby reach the purpose of incremental oil production.
The utility model is reasonable in design, reliable operation, utilize it can directly produce steam and directly annotate well, also can be compressed, washing, desulfurization and dry back produce gaseous carbon dioxide by transformation absorbing carbon dioxide device and annotate well, reaches the purpose that improves heavy oil production and recovery ratio.
Description of drawings:
Accompanying drawing is general structure of the present utility model and process flow diagram.Among the figure, label " 12 ", " 13 " are respectively oil well casing and oil pipe.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, form by boiler 1, high-pressure hydraulic pump 2, compressor 3, washing desulfurizing tower 4, clean-up bed 5, adsorbent bed 6, displacement apparatus 7, vacuum pump 8, nitrogen compressor 9, carbon-dioxide gas compressor 10, blending tank 11.Wherein, boiler 1 pure water is provided by the high-pressure pump more than the 15MPa, and boiler oil can be coal, oil or fuel gas.Washing desulfurizing tower 4 is packed towers, and filler is that metal, plastics or pottery are made, and also can be that coke, ore or vegetable silk are made, and cleaning solution is weakly alkaline solutions such as water, aqueous sodium carbonate or ammoniacal liquor.Adsorbent bed 6, displacement apparatus 7, vacuum pump 8 are formed transformation absorbing carbon dioxide recovery system, and each assembly connects with relevant valve pipe.Adsorbent bed 6 is made up of the absorber of adorning activated alumina, silica gel, active carbon or molecular sieve solid filler in 5, unstripped gas enters from the absorber bottom, obtaining absorption tail gas in the absorber outlet is nitrogen and minor amounts of oxygen, obtains carbon dioxide in the absorber bottom by steps such as replacing, vacuumize.The high steam that boiler produces mixes back injection well with chemical agent in blending tank 11, the gaseous carbon dioxide after the pressurization also can mix with chemical agent or steam, nitrogen, injects well together.
