Abstract
Provided is a self-detaching gas lift production increasing device. The lower portion of an upper oil pumping pipe column of a pump is connected with a gas lift valve, the lower portion of the gas lift valve is connected with the upper portion of a lower oil pumping pipe column, the lower portion of the lower oil pumping pipe column is connected with the upper portion of an oil well pump, the lower portion of the oil well pump is connected with the upper portion of an oil-gas separator, a plug is arranged on the lower portion of the oil-gas separator, the upper oil pumping pipe column, the gas lift valve, the lower oil pumping pipe column, the oil well pump, the oil-gas separator and the plug are connected in sequence and enter a sleeve pipe, natural gas separated from the oil-gas separator can enter the oil pumping pipe columns, is mixed with pumped-out crude oil and is pumped to a gathering and transportation station to be recycled after reaching the opening set pressure of the gas lift valve, after a well mouth sleeve pipe valve is closed, the oil-gas separator can separate the natural gas normally, the oil well pump can work normally, the well yield is high, the natural gas separated by the oil-gas separator is all recycled, the gas production rate of an oil well is increased, and meanwhile the natural gas can be prevented from entering the atmosphere and causing environmental pollution. Therefore, the self-detaching gas lift production increasing device has prominent economic benefits and social benefits.
Description
Technical field
The utility model is the tubing string that petroleum industry oil recovery gas recovery well is used, and is a kind of self-separation gaslift increasing device.
Background technology
Oil well pump is when the large crude oil of pumping air content, and the natural gas in crude oil can enter in pump, light reduce the pump efficiency of pump, reduces oil well output, heavy oil well pump generation gas lock, and oil well is produce oil not.The way addressing this is that is at present generally, under oil well pump, gs-oil separator is installed, and reduces the tolerance that enters oil well pump, increases well oil output.But the oil well being lowered to after gs-oil separator must will open wide sleeve valve, and gs-oil separator could be sent out brightness effect, so after being lowered to gs-oil separator, isolated natural gas will be put into atmosphere from sleeve valve.If do not open wide sleeve valve, natural gas is gathered in sleeve pipe casing pressure is raise, and gas-liquid interface can arrive pump intake, can enter equally the production that affects pump in oil well pump.Natural gas bleeds off and can lose natural gas from sleeve valve, reduces the economic benefit of oil well; The natural gas of putting into atmosphere also can cause environment pollution, produces imponderable serious adverse consequences.
Summary of the invention
The purpose of this utility model is to provide a kind of self-separation gaslift increasing device, overcomes the problem that prior art exists, and makes the isolated natural gas of gs-oil separator not put into atmosphere, increases oil well economic benefit, avoids environment pollution.
The purpose of this utility model is achieved in that and comprises sleeve pipe, upper pumping pipe string, lower pumping pipe string, oil well pump, gs-oil separator, plug, on pump, pumping pipe string bottom is connected with gas lift valve, gas lift valve bottom is connected with lower pumping pipe string top, lower pumping pipe string bottom is connected with oil well pump top, oil well pump bottom is connected with gs-oil separator top, plug is installed in gs-oil separator bottom, and upper pumping pipe string, gas lift valve, lower pumping pipe string, oil well pump, gs-oil separator, plug are lowered in sleeve pipe after connecting successively.
The depth of setting of gas lift valve is 40-200m.
The beneficial effects of the utility model: install after gas lift valve between upper pumping pipe string and lower pumping pipe string, can close the sleeve valve of well head, the natural gas of separating from gs-oil separator is reaching the unlatching setting pressure of gas lift valve, gas lift valve is opened, the natural gas that gs-oil separator is separated reclaims be pumped down to gathering station after mixing with the crude oil of extracting out in gas lift valve enters pumping pipe string after, therefore, the utility model has overcome the problem that prior art exists, after wellhead casing pipe valve closing, gs-oil separator also can normal separation natural gas, oil well pump can be worked, oil well output is high, the natural gas that gs-oil separator is separated need not be put into atmosphere, whole natural gass of oil well are recovered, increased the gas production of oil well, also can avoid natural gas to enter simultaneously and in atmosphere, cause environment pollution, therefore, the utlity model has significant economic benefit and social benefit.
Accompanying drawing explanation
Accompanying drawing is the schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Embodiment of the present utility model comprises sleeve pipe 1, upper pumping pipe string 2, gas lift valve 3, lower pumping pipe string 4, oil well pump 5, gs-oil separator 6, plug 7, on pump, pumping pipe string 2 bottoms are connected with gas lift valve 3, gas lift valve 3 bottoms are connected with lower pumping pipe string 4 tops, lower pumping pipe string 4 bottoms are connected with oil well pump 5 tops, oil well pump 5 bottoms are connected with gs-oil separator 6 tops, plug 7 is installed in gs-oil separator 6 bottoms, in actual production process, between gs-oil separator 6 and plug 7, be connected 2-6 according to oil pipe, upper pumping pipe string 2, gas lift valve 3, lower pumping pipe string 4, oil well pump 5, gs-oil separator 6, plug 7 is lowered in sleeve pipe 1 after connecting successively.The depth of setting of gas lift valve 3 is 40-200m, and gas lift valve 3 is lowered in this degree of depth guarantee manufacturing process on gas-liquid interface, and gas lift valve 3 can reliably be opened under the pressure of setting, and just can make the natural gas of separating enter in pumping pipe string 2.
The effect of plug 7 is to allow oil gas by the flow passage of setting, make gas mixture carry out spiral separation from the top of gs-oil separator 6 enters, natural gas enters in the annular space between sleeve pipe 1 and pumping pipe string 4 and flows up into into gas lift valve 3 in gs-oil separator 6, the crude oil after degasification from gs-oil separator 6 interior to be pressurized rear discharge in inflow oil well pump.
