The utility model has advantages of simple structure and easy operation, and is quite suitable for the application in the field.
Description
Technical field:
The utility model relates to a kind of oil field and improves the injectant that recovery ratio is used, particularly a kind of nitrogen foam generator.
Background technology:
Along with the oil field steam drive development enters stage middle and later periods, steam is serious along channelling, fingering, tonguing and the steam overlap phenomenon of high permeability zone, makes steam consumption quantity big, and the producing well recovery ratio reduces, the economic benefit variation.Most of poor permeability or the high oil-containing zone that is in the bottom are not subjected to steam and involve in the oil reservoir, steam enters producing well with narrow passage, sweep efficiency is very little, especially thick heavy crude reservoir or reservoir physical property, permeability differ bigger thin mutual shape oil reservoir in, vertical air-breathing thickness of oil reservoir or development degree generally only about 50% and serious uneven, oil recovery factor reduces.
The utility model content:
The purpose of this utility model is to provide a kind of nitrogen foam generator.Using the nitrogen foam profile control technology, excavate whole potential of whole series of strata, is to improve main, the valid approach of steam flooding effect.
The utility model is to realize like this, by air and liquid mixer (1), one way valve (2), pressure meter (3), stop valve (4), ball valve (5), advance Teat pipette (6), piping filter (7), measuring pump (8), medicinal cupping (9), agitator (10), electrical control cubicles (11) is formed, medicinal cupping (9) is arranged on electrical control cubicles (11), agitator (10) is arranged in the medicinal cupping (9), medicinal cupping (9) is connected with measuring pump (8) by piping filter (7), medicinal cupping (9) bottom with advance Teat pipette (6) and be connected, advance access valve (5) under the Teat pipette (6), measuring pump (8) bottom is connected to air and liquid mixer (1) respectively, one way valve (2), pressure meter (3), stop valve (4).
The utility model is owing to have agitator in the employing medicinal cupping, medicinal cupping is connected with measuring pump by piping filter, the medicinal cupping bottom with advance Teat pipette and be connected, advance access valve under the Teat pipette, the measuring pump bottom is connected to air and liquid mixer respectively, can make the even hybrid concurrency of nitrogen and foam give birth to foam, and enter oil well, utilize nitrogen foam profile control can obviously improve viscous crude vapour and drive the well group development degree, be the whole potential that excavate whole series of strata, the efficient ways of improving steam flooding effect, raising recovery ratio and economic benefit, have good application prospects.Simple in structure, processing ease is well suited for The field.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model by air and liquid mixer 1, one way valve 2, pressure meter 3, stop valve 4, ball valve 5, advance Teat pipette 6, piping filter 7, measuring pump 8, medicinal cupping 9, agitator 10, electrical control cubicles 11 and form, medicinal cupping 9 is arranged on electrical control cubicles 11, agitator 10 is arranged in the medicinal cupping 9, medicinal cupping 9 is connected with measuring pump 8 by piping filter 7, medicinal cupping 9 bottoms with advance Teat pipette 6 and be connected, advance 6 times access valves 5 of Teat pipette, measuring pump 8 bottoms are connected to air and liquid mixer 1, one way valve 2, pressure meter 3, stop valve 4 respectively.
Heavy crude reservoir accounts for the sizable ratio of China's oil, oil recovery by heating is the main means of thickened oil recovery, along with thickened oil steam-stimulated exploitation has entered the middle and later periods, the gas oil ratio quickening of successively decreasing, arrived the economic exploitation limit, must change mining type, steam flooding is as the important substituted technique of conversion mining type, test has been carried out for many years in each oil field, owing to exist steam overlap, fingering, tonguing and scurry phenomenons such as groove, cause vertical air-breathing thickness of oil reservoir and development degree wretched insufficiency, therefore the thick oil steam drive exploitation never produces a desired effect, utilizing nitrogen foam profile control can obviously improve viscous crude vapour and drive the well group development degree, is the whole potential that excavate whole series of strata, improve the steam flooding effect, improve the efficient ways of recovery ratio and economic benefit, have good application prospects.
