Description
Technical field:
The present invention relates to a kind of ground installation and method that is used for tertiary oil production in oil field technology and production process.
Background technology:
Along with oil field development enters the middle and later periods, the oil extraction difficulty increases day by day, comprises CO 2Drive, N 2Drive, various displacement of reservoir oil mining types such as flue gas flooding use more and more at interior tertiary oil recovery technology.Flue gas flooding recovers the oil and has and CO 2Similar displacement of reservoir oil characteristic and N 2Displacement of reservoir oil advantage, the resultant effect that improves recovery ratio especially for HEAVY OIL RESERVOIRS is better than N 2And CO 2, and flue gas is used for field produces is that harmful substance with contaminated environment becomes the field produces useful resource, help environmental protection, thereby its application value is higher.When carrying out the flue gas oil recovery, must carry out dedusting and desulfurization, denitration to flue gas, this is a very complicated process, and present on-the-spot commercial Application, to produce the equipment that adopts in implementing too huge, and processing procedure is comparatively complicated, can not satisfy the needs of field produces.Especially at present the apparatus for treating flue gas that uses is not to NO XHandle NO XAnd SO 2Meet water and form strong acid, heavy corrosion surface line, equipment and down-hole oil tube, thereby limited development and application that flue gas is recovered the oil.
Summary of the invention:
Thereby the object of the present invention is to provide and a kind ofly in the flue gas oil recovery process, can carry out desulfurization, denitration, dust removal process and effectively reduce NO in the flue gas flue gas X, SO 2, dust content, help fume desulfuring and denitrifying dedust apparatus and method that the flue gas oil recovery technique is used.
The present invention realizes like this.The device that the present invention adopts is made up of air blast, forced air cooler, solution-air blender, circulating pump, circulating tank and connecting pipe, and air blast one side is connected with steam boiler flue gas efferent duct by pipeline, and opposite side is connected with forced air cooler by pipeline; Forced air cooler, circulating pump are connected with the solution-air blender by pipeline respectively, and forced air cooler is gentle-and the liquid mixer connecting pipe is provided with valve; Solution-air blender output is connected with circulating tank by pipeline, and the circulating pump other end is connected with circulating tank by the pipeline which is provided with valve.Need for ease of the scene, above-mentioned package unit can be arranged on movably and drag on the sled.Method provided by the invention is, from the flue gas of steam boiler by air blast, after the forced air cooler cooling, in the solution-air blender with the Na that pumps into by circulating pump 2The CO3 treatment fluid fully mixes, and then, enters and reaches specification requirement after fully absorbing by treatment fluid once more in the circulating tank; Through NO in the flue gas that obtains after the above-mentioned desulfurization of the device that adopts, denitration, the dust removal process X, SO 2, dust content reduces greatly, can inject into well by gas injecting pipe and down-hole string, is used for the flue gas flooding DP technology.
The apparatus structure compactness that the present invention adopts, equipment is installed and method is easy to implement, and production cost is low, and desulfurization, denitration, efficiency of dust collection height are effective, for the development and the application of flue gas oil recovery technique provides the reliable technique assurance.
Description of drawings:
Accompanying drawing is the general structure and the process flow diagram of equipment therefor of the present invention.Among the figure, label " 6 " is a steam boiler.
The specific embodiment:
The present invention is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the device that the present invention adopts is made up of air blast 1, forced air cooler 2, solution-air blender 3, circulating pump 4 and circulating tank 5, its structure, assembled relation are as follows: air blast 1 one sides are connected with steam boiler 6 flue gas efferent ducts by pipeline, and opposite side is connected with forced air cooler 2 by pipeline; Forced air cooler 2, circulating pump 4 are connected with solution-air blender 3 by pipeline respectively; Connecting pipe between forced air cooler 2 gentle-liquid mixers 3 is provided with valve, and solution-air blender 3 outputs are connected with circulating tank 5 by pipeline, and circulating pump 4 other ends are connected with circulating tank 5 by the pipeline which is provided with valve.Wherein, air blast 1 adopts by electric motor driven flue air blast, and its fan blade and trunk line are carried out chemical deep layer preservative treatment.Forced air cooler 2 import calibers are 200mm, 250 ℃ of inlet temperatures, 45 ℃ of outlet temperatures, minimum admission pressure 0.01MPa.Air and liquid mixer 3 adopts Hi-mixer.Circulating pump 4 adopts LSB-300 type circulating pump.Circulating tank 5 high 2m, wall thickness 6mm, external diameter 1.2m, volume 2m 3, withstand voltage 0.2MPa, outlet caliber 180mm or 200mm.
The concrete implementation step of method provided by the invention is as follows:
Process of gas path: the flue gas metering that injection boiler 6 flues are discharged is laggard goes into forced air cooler 2, after the cooling (temperature drops to below 45 ℃ from 250 ℃) of subcooler 2, enter air and liquid mixer 3 and fully be mixed into circulating tank 5 and fully absorb, be respectively equipped with sample tap in the front and back of circulating tank 5 and change with the composition that detects flue gas.Wherein flue gas examination leading indicator is NO X, SO 2, and dust content, the flue gas technical indicator after handling through circulating tank is respectively: NO X--20mg/Nm 3, SO 2--20mg/Nm 3, dust--5mg/Nm 3The pressure of whole device is normal pressure, i.e. 0.1MPa.
Liquid road flow process: absorbent fully contacts, reacts with flue gas from top to bottom at circulating tank 5 internal upper parts spray.Consider complete equipment skid movably characteristics and environmental protection requirement, adopt the closed cycle water-washing method, from the water lotion of circulating tank discharge, add alkali after the filtration and improve pH value, keep the pH value scope at 9-12, carry out recycling, up to end cycle (1-2 days).
