First period: " exploitation early period ".
(each control valve is in close state) has oil-water-gas three-phase substance in extraction layer and enters gas-liquid point by oil pipe 2
From in pump 9, pass through the abundant work of gas-liquid separation pump 9, it will sub-argument goes out gas and liquid, and wherein gas enters through gas-guide tube 10
In gas storage metering pump 7, and liquid can directly be entered in water-oil separating pump 8 by oil guide pipe 11, can be by liquid in water-oil separating pump 8
Body is adequately separated into crude oil and water two parts, and wherein water can flow back to implanted layer by the way that downcomer 12 is counter, and crude oil can then pass through
Oil guide pipe 11 enters in oil storage measuring pump 6.Due to exploitation early period that the period is oil well, the more gas of oil are few, therefore measure in gas storage
The increase that gas in pump 7 will be slow, and the oil in oil storage measuring pump 6 then becomes rapidly more, opens third valve 15 at this time, leads to
It crosses electric submersible pump 4 and crude oil is directly passed through into 2 pumping of oil pipe to well head；On the other hand, when the gas in gas storage metering pump 7, accumulation one
After quantitative, electric submersible pump is closed, the second valve 13, the first valve 16 are opened, so that the crude oil in oil storage measuring pump 6 passes through conduit
It enters in air-fuel mixture pump 5, so that oil gas is sufficiently mixed, pressurizes, can be incited somebody to action by lift mode after the 4th valve 14 to be opened
Part crude oil is lifted to well head, completes oil recovery, gas production work.
Facts have proved: in " exploitation early period " type, the more gas of oil well output oil are few, thus in actual operation, can respectively into
Row exploitation, i.e., the second valve 13 is in close state always, and third valve 15 is opened, and electric submersible pump 4 works, when in gas storage metering pump
After tolerance reaches certain magnitude, electric submersible pump 4 is closed, opens the 4th valve 14, the first valve 16 makes gas pass through air-fuel mixture
Pump 5 directly rises to well head.
Second period: " exploitation mid-term ".
(each control valve is in close state) has oil-water-gas three-phase substance in extraction layer and enters gas-liquid point by oil pipe 2
From in pump 9, pass through the abundant work of gas-liquid separation pump 9, it will sub-argument goes out gas and liquid, and wherein gas enters through gas-guide tube 10
In gas storage metering pump 7, and liquid can directly be entered in water-oil separating pump 8 by oil guide pipe 11, can be by liquid in water-oil separating pump 8
Body is adequately separated into crude oil and water two parts, and wherein water can flow back to implanted layer by the way that downcomer 12 is counter, and crude oil can then pass through
Oil guide pipe 11 enters in oil storage measuring pump 6.Since the period is exploitation mid-term, oil well output oil and amount of carbon dioxide are balanced, because
And can directly open the second valve 13, the 4th valve 14 and the first valve 16, due to the property of gas, thus gas necessarily compares
The flow velocity of oil is fast, the work pumped using air-fuel mixture, and directly act will be mixed after the crude oil and gas that flow through by the second valve 13
Rise to well head.
It facts have proved: to the oil well for being in the period, it is desirable that air-fuel mixture pump 5 has very high working efficiency, by a large amount of
Gas band each take away a small amount of crude oil, while eliminating the work of electric submersible pump.
Third period: " exploitation later period ".
(each control valve is in close state) has oil-water-gas three-phase substance in extraction layer and enters gas-liquid point by oil pipe 2
From in pump 9, pass through the abundant work of gas-liquid separation pump 9, it will sub-argument goes out gas and liquid, and wherein gas enters through gas-guide tube 10
In gas storage metering pump 7, and liquid can directly be entered in water-oil separating pump 8 by oil guide pipe 11, can be by liquid in water-oil separating pump 8
Body is adequately separated into crude oil and water two parts, and wherein water can flow back to implanted layer by the way that downcomer 12 is counter, and crude oil can then pass through
Oil guide pipe 11 enters in oil storage measuring pump 6.Due to the exploitation later period that the period is oil well, the few gas of oil is more, therefore in oil storage measuring
Crude oil in pump 6 will be slow increases, and the gas in gas storage metering pump 7 then increases rapidly, need at this time the 4th valve 14 of unlatching,
First valve 16 makes bulk gas be ejected to well head, since all devices are in underground, thus oil storage, gas metering pump 6,7 bodies
Product will not be very big, and the compressibility that crude oil has is not also strong, thus oil storage measuring pump 6 can quickly reach its reserves peak value,
At this moment it needs to open the second valve 13, allows the crude oil in oil storage measuring pump 6 to enter in air-fuel mixture pump 5, pass through the air-fuel mixture
Crude oil and gas are sufficiently mixed by pump 5, and crude oil is lifted to ground by gas.
In the oil well life cycle of oil field development, the exploitation most of the time in period is distributed in the middle and later periods, and the later period occupies
It is more.Facts have proved: the underground oil gas exploits work with the later period that mining method is very suitable to carbon dioxide flooding oil well, which can be with
Remove brought unnecessary trouble when electric submersible pump work from, while crude oil is lifted to by ground by lift mode, utilizes significantly
The resource of gas.
The device environmental pollution of the utility model is small, the water of extraction direct reinjection into reservoir after down-hole treatment, entire to fill
It is minimum to set occupied area, is to complete to operate in underground, is particularly suitable for offshore platform operation.Entire process flow method is simple,
Be lost in the process it is less, be suitable for oil extraction in oil field technology.
