Description
Technical field
This utility model is related to the Christmas tree of petroleum industry, and particularly a kind of oil jacket, with adopting jet pump, mainly should
For rod-pumped well, so that oil pipe is adopted together with the crude oil in sleeve pipe, there is the using effect of energy-conservation, potentiation, reduces cost.
Background technology
The problem of sleeve pipe recovery of oil always very puzzlement in oilfield production.The key of problem is exactly sleeve pipe oil
Producing well, casing pressure is generally less than the outer defeated pressure of pipeline, so being difficult to carry out oil pipe and sleeve pipe carry out using same petroleum pipeline
Harvesting.Also once mjector is taken out using excessively a kind of set, this device also can produce set and take out effect, but causes in this device production process
Back pressure raises deep well pump pump efficiency and reduces, and is eliminated because effect is undesirable.Mainly periodically reclaimed using tank car at present, cost input
Larger.And sleeve pipe oil mostly is low aqueous crude oil, economic worth is higher, such as irregular recovery easily lose stolen, stolen
Cause wellhead equipment, facility to damage and environmental pollution simultaneously.So being badly in need of a kind of energy-conserving and environment-protective of design not affect oil pumper deeply
The device that crude oil in the oil pipe and sleeve pipe of oil well can be produced simultaneously on the premise of well pump pump efficiency.
Content of the invention
The purpose of this utility model is that a kind of oil jacket of offer is same adopts jet pump, in the feelings not affecting oil pumper deep well pump pump efficiency
Under condition, solve the problems, such as current sleeve pipe recovery of oil costly, cannot harvest with pipeline, reduce production cost, prevent from sleeve pipe
Steal the loss that crude oil causes.
This utility model is realized in：Adopt jet pump includes pump core to a kind of oil jacket together, is provided with diffusion chamber and nozzle, pump
It is suction chamber between the trunnion of core and nozzle, the cavity wall of suction chamber is provided with liquid flow hole and is connected with inner sleeve；One end of pump core sets
There is ball-and-seat, the valve pocket of ball-and-seat is connected with nozzle；It is equipped with by-pass prot at the two ends of inner sleeve, outside this by-pass prot and inner sleeve
The shell body connection in face；Pump core is arranged in inner sleeve and can inside slide, oil jacket annular space connector is located at shell body
Outside and inner sleeve insertion.
Compared with prior art, notable using effect of the present utility model is：This device is arranged on well head, with taking out of down-hole
The pumping stroke of oil machine deep well pump matches, by oppositely positioned for pump core in inner sleeve, reverse to the well liquid in oil well middle sleeve
Jet aspirates, and realizes oil jacket and exploits simultaneously.The pump core of this device is to be in travelling state with the pumping stroke of oil pumper deep well pump,
When rod-pumped well deep well pump piston stroking upward, close with the pressure rise of this device well liquid entrance, ball-and-seat, in oil pipe
Liquid-driving pump core moves to well liquid outlet, and the by-pass prot of well liquid inlet side in inner sleeve opens, the liquid in oil pipe from
Well liquid outlet is discharged.When deep well pump descent of piston, the reduced pressure of well liquid entrance, liquid and falls in well liquid outlet
Stream, promotes pump core to move to well liquid import, the bypass bore closure of this side, and suction chamber is connected with oil jacket annular space connector.With depth
The descent of piston of well pump, between well liquid import and well liquid outlet, pressure reduction becomes big, and liquid is through ball-and-seat, nozzle, suction chamber and larynx
Pipe, diffusion chamber form jet, produce vacuum environment in suction chamber, the liquid in sleeve pipe is drawn into suction chamber and through trunnion, expansion
Scattered chamber and well liquid import enter in oil pipe, and when the piston of deep well pump is up again, oil jacket mixed liquor produces ground together.
This device utilizes pump core backward jet, can effectively use cooperatively with oil pumper deep well pump, to oil pumper deep well pump
Pump efficiency does not produce any impact, and achievable oil pipe and sleeve pipe harvest with pipeline simultaneously, and processing cost is low, easy for installation, no
Follow-up expense.Solve the problems, such as current sleeve pipe recovery of oil costly, cannot harvest with pipeline, reduce production cost, prevent
Steal the massive losses that crude oil causes from sleeve pipe, there is significant economic benefit and social benefit.
