Description
Technical field
The utility model relates to carbon dioxide oil recovery pressure injection equipment, is specifically related to the auto water compensating device for boiler of carbon dioxide oil recovery pressure injection equipment.
Background technology
Carbon dioxide flooding oil tech, be exactly in carbon dioxide injection oil reservoir to improve tar productivity.International Energy Agency's assessment is thought, the resource that the whole world is applicable to carbon dioxide drive exploitation is about 3,000 hundred million ~ 6,000 hundred million barrels.Because carbon dioxide is a kind of gas that solubility is all very high in You Heshui, when it is dissolved in crude oil in a large number, crude oil volumetric expansion, viscosity decline can be made, the interfacial tension between profit can also be reduced.Compared with other technology of reservoir sweep, carbon dioxide drive has the advantages such as the scope of application is large, displacement of reservoir oil cost is low, tar productivity raising is remarkable.
Carbon dioxide drive is a ripe oil recovery technique.According to incompletely statistics, the carbon dioxide drive project that the current whole world is being implemented has nearly 80.The U.S. is that carbon dioxide drive project carries out maximum countries, and the annual amount of carbon dioxide injecting oil reservoir is about 2,000 ten thousand ~ 3,000 ten thousand tons, wherein 3,000,000 tons of waste gas from coal gasification plant and chemical fertilizer factory.
According to " on Chinese Continental, developed field improves recovery ratio second time Potential Evaluation and Study of developing strategy " result, carbon dioxide has huge application potential in China's oil exploitation.The existing explored 63.2 hundred million tons of low-permeability oil deposit crude oil reserves of China, especially wherein about 50% reserves not yet employed, use carbon dioxide flooding to have more obvious technical advantage than water drive.Can predict, the continuous expansion with range of application is improved in the development along with technology, and carbon dioxide improves Development Response of Oilfield by becoming China, improves the valuable source of oil recovery factor.
By the oil reservoir of carbon dioxide injection energy decline, oil gas field recovery ratio can be improved, become the common recognition of world many countries oil exploration industry.Namely carbon dioxide purity can be used for improving recovery ratio more than 90%.After carbon dioxide is water-soluble in stratum, the viscosity of water can be made to increase by 20% ~ 30%, and transfer ability improves 2 ~ 3 times; After carbon dioxide is dissolved in oil, make crude oil volumetric expansion, viscosity reduces by 30% ~ 80%, and oil water interfacial tension reduces, and is conducive to improving rate of oil production, displacement efficiency and collection residual oil.Carbon dioxide drive generally can improve recovery ratio 7% ~ 15%, extends 15 ~ 20 years oil well production life-spans.Carbon dioxide source can from industrial plants as reclaimed the emissions such as power plant, chemical fertilizer factory, cement plant, chemical plant, oil plant, gas plant.Domestic used carbon dioxide oil recovery pressure injection equipment cannot give boiler replenishing water automatically at present, and need the water-refilling operation of Artificial Control boiler, workload is large.
Summary of the invention
The purpose of this utility model is: the auto water compensating device for boiler providing carbon dioxide oil recovery pressure injection equipment, is carried out the water level in automatic control boiler by automatic water-replenishing device, improves the operating efficiency of carbon dioxide oil recovery pressure injection.
The utility model technical solution is: this auto water compensating device for boiler comprises boiler and automatic water supply tank, at boiler other installation automatic water supply tank, the filling pipe of automatic water supply tank is communicated with the water supplement port of boiler, filling pipe installs magnetic valve, automatic water supply tank drives the mouth of a river into, and water inlet is communicated with water inlet pipe, and water inlet installs sealing ring through hinge, sealing ring connects pole one end, and the pole other end installs ball float.
When the water in boiler produces the reduction of loss water level, water in automatic water supply tank enters boiler by filling pipe, water level now in automatic water supply tank reduces, ball float in automatic water supply tank also just declines, ball float opens water inlet through pole band dynamic seal ring, and water fills into automatic water supply tank from water inlet pipe, water inlet; When the water level of boiler raises, shut electromagnetic valve cuts off moisturizing, and water continues to fill into automatic water supply tank from water inlet pipe, water inlet, when the water level in automatic water supply tank raises, ball float and then raises, and ball float is closed water inlet through pole band dynamic seal ring and stoped the water at water source to enter automatic water supply tank.
The beneficial effects of the utility model are: this auto water compensating device for boiler achieves the automatic control of boiler water level, reduce the working strength of field worker, the reservoir storage maintained in boiler remains within the water level range required for work, solve because boiler heats the loss causing water, ensure the normal safe operation of boiler, make the work of carbon dioxide oil recovery pressure injection equipment more effective.
Accompanying drawing explanation
Fig. 1 is the utility model scheme of installation.
In figure: 1 boiler, 2 automatic water supply tanks, 3 filling pipes, 4 water supplement ports, 5 magnetic valves, 6 water inlets, 7 water inlet pipes, 8 hinges, 9 sealing rings, 10 poles, 11 ball floats.
Detailed description of the invention
As shown in Figure 1, this auto water compensating device for boiler comprises boiler 1 and automatic water supply tank 2, boiler 1 is other installs automatic water supply tank 2, the filling pipe 3 of automatic water supply tank 2 is communicated with the water supplement port 4 of boiler 1, filling pipe 3 is installed magnetic valve 5, automatic water supply tank 2 drives the mouth of a river 6 into, water inlet 6 is communicated with water inlet pipe 7, water inlet 6 installs sealing ring 9 through hinge 8, and sealing ring 9 connects pole 10 one end, and pole 10 other end installs ball float 11.
When the water in boiler produces the reduction of loss water level, water in automatic water supply tank 2 enters boiler 1 by filling pipe 3, water level now in automatic water supply tank reduces, ball float 11 in automatic water supply tank also just declines, ball float 11 is with dynamic seal ring 9 to open water inlet 6 through pole 10, and water fills into automatic water supply tank 2 from water inlet pipe 7, water inlet 6; When the water level of boiler 1 raises, shut electromagnetic valve 5 cuts off moisturizing, water continues to fill into automatic water supply tank 2 from water inlet pipe 7, water inlet 6, when the water level in automatic water supply tank raises, ball float 11 and then raises, and ball float 11 is closed water inlet 6 through pole 10 with dynamic seal ring 9 and stoped the water at water source to enter automatic water supply tank 2.
