Description
Technical field
The utility model relates to a kind of beam well and adds pour-point depressant device, solves that oily beam oil pumper heavy oil wells is difficult to be extracted into well head and ground to be difficult to collection defeated by viscous crude large for viscosity, causes motor overload operate, waste electric energy and affect the problem of oil well production.
Background technology
Current oil-field thick-oil well recovers the oil mainly mechanical oil recovery, and mechanical oil recovery equip ment is beam-pumping unit mainly.Viscous crude large for viscosity is extracted into well head by oily beam oil pumper heavy oil wells difficulty, is namely to be extracted into wellhead ground to be also difficult to collect defeated, motor overload is operated, causes rod parting salvaging, motor overload operates the problem of wasting electric energy and having a strong impact on oil well production.
Summary of the invention
The purpose of this utility model is to provide a kind of beam well and adds pour-point depressant device, overcomes the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises pressing plate seat, pressing plate, piston rod, plunger displacement pump, double-direction single-flow valve, chemical tank and flexible pipe, it is characterized in that: on front side of oil pumping frame, middle and upper part is provided with a chemical tank, on the right side of oil pumping frame, middle and upper part is provided with a plunger displacement pump fixed with oil pumping frame by plunger displacement pump base, middle and lower part has one piece of pressing plate fixed by pressing plate seat and walking beam on the right side of walking beam, the center of pressing plate and the center of piston rod are on same center line; The outlet valve of chemical tank is connected with the import of double-direction single-flow valve by flexible pipe, and the outlet of double-direction single-flow valve is connected with the sleeve valve of production tree by flexible pipe.
Described plunger displacement pump welds with plunger displacement pump base, angle 45 degree or 40 degree.
Described plunger displacement pump adopts the plunger displacement pump of inflater type.
The utility model has the following advantages:
1, utilize the walking beam up and down reciprocatingly oscillatory forces of beam-pumping unit, act on the piston rod of plunger displacement pump, piston rod produces reciprocating motion under the effect of back-moving spring, is added to by pour-point depressant in oil well, need not add other equipment.
2, pour-point depressant is added from sleeve pipe, runs to shaft bottom and returns out from oil pipe, both gives wellbore oil viscosity reduction, also gives the reducing crude oil viscosity of gathering line, serves dual usefulness, ensure that the normal production of oil well.
3, structure is simple, principle is reliable, improves production time efficiency and the oil well output of oil well, prevents the accident of blocking pipeline to occur, reduces cost of crude oil production.

Detailed description of the invention
For disclosing the technical solution of the utility model further, elaborated by embodiment below in conjunction with Figure of description:
The utility model comprises pressing plate seat 1, pressing plate 2, piston rod 3, plunger displacement pump 4, double-direction single-flow valve 5, agent outlet valve 6, chemical tank 7 and flexible pipe, it is characterized in that: on front side of oil pumping frame, middle and upper part is provided with a chemical tank 7, on the right side of oil pumping frame, middle and upper part is provided with a plunger displacement pump 4 fixed with oil pumping frame by plunger displacement pump base 1, middle and lower part has one piece of pressing plate 2 fixed with walking beam by pressing plate seat 1 on the right side of walking beam 9, the center of pressing plate and the center of piston rod 3 are on same center line; The outlet valve 6 of chemical tank is connected by the import of flexible pipe with double-direction single-flow valve 5, and the outlet of double-direction single-flow valve is connected with the sleeve valve of production tree by flexible pipe.
Utility model works principle is that motor rotation is pumped by the generation of reduction box variable velocity zone dynamic balance weight, connecting rod, walking beam 9, horse head 8, polished rod 10 and oil well pump, in-place oil is extracted into ground transportation network, in its reciprocating process, walking beam 9 is pressure piston rod 3 back and forth, makes plunger displacement pump carry out dosing work under the effect of double-direction single-flow valve 5.When up under the effect of piston rod at back-moving spring, piston rod drives plunger up, by the pour-point depressant in chemical tank 7 by agent outlet valve 6, flexible pipe and two-way unidirectional ball-and-seat 5 import suction plunger displacement pump, when the pressing plate 2 on walking beam presses piston rod descending, the pour-point depressant be drawn in plunger displacement pump is discharged to oil casing annular space by the outlet of double-direction single-flow valve, flexible pipe and sleeve valve, go downwards to shaft bottom by gravity, then extract out through oil well pump and crude oil one piece, be passed to central gathering station by gathering line.Pour-point depressant is added from sleeve pipe, runs to shaft bottom and returns out from oil pipe, both gives wellbore oil pour-viscosity reduction, also gives the pour point depression of crude oil viscosity reduction of gathering line, serves dual usefulness, ensure that the normal production of oil well.
