Abstract
The utility model relates to the field of oil field extraction, and specifically relates to a numerical-control reciprocating-type oil-submersible electric pump lifting system with an airproof device; a depositing-type airproof device is connected between an oil pump and a motor of a device; the depositing-type airproof device comprises an outer barrel and an inner barrel; the outer barrel is sleeved on the outer side of the inner barrel; an air exhaust hole is formed on the upper end of the outer barrel; an air/liquid inlet hole is formed on the middle part of the outer barrel; and a liquid inlet is formed on the lower end of the inner barrel. According to the utility model, airlock reaction reduction in a production procedure is realized; the influence of gas to a pump is reduced; pump effect is improved; oil well output is increased; therefore, the numerical-control reciprocating-type oil-submersible electric pump lifting system solves disadvantages of large airlock influence on the current numerical-control reciprocating-type oil-submersible electric pump, about 35% pump effect and seriously influenced oil well output.
Description
Technical field:
The utility model relates to a kind of oil extraction in oil field technical field, particularly a kind of band air trap device numerically controlled reciprocating submersible pump hoisting system.
Background technique:
Numerically controlled reciprocating submersible pump is in application process, and its pump efficiency is subjected to the interior gas influence of oil well larger, and the common pump efficiency of numerically controlled reciprocating submersible pump can reach more than 60%, but on the high oil well of gas production, because the gas lock impact, pump efficiency only has about 35%, has had a strong impact on the output of oil well.
The model utility content:
The technical problems to be solved in the utility model provides a kind of band air trap device numerically controlled reciprocating submersible pump hoisting system, and this device has been realized reducing in process of production the gas lock effect, reduces gas to the impact of pump, improves pump efficiency, improves oil well output.Overcome existing numerically controlled reciprocating submersible pump and affected greatly by gas lock, pump efficiency only has about 35%, has had a strong impact on the deficiency of oil well output.
Technical solution adopted in the utility model is: a kind of band air trap device numerically controlled reciprocating submersible pump hoisting system comprises oil well pump and motor; Connect the decanter type air trap device between oil well pump and the motor, the decanter type air trap device comprises urceolus and inner core, and urceolus is sleeved on the inner core outside, and the urceolus upper end has exhaust port, and the middle part has air inlet liquid hole; The inner core lower end has inlet opening.
The beneficial effects of the utility model are: the utility model has been owing to having adopted between oil well pump and motor the mode that connects the decanter type air trap device, thereby has the effect of the gas lock of reduction, reduces gas to the effect of the impact of pump, improves pump efficiency, improves oil well output.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present utility model.
Embodiment:
As shown in drawings, a kind of band air trap device numerically controlled reciprocating submersible pump hoisting system comprises oil well pump 1 and motor 3; Connect decanter type air trap device 2 between oil well pump 1 and the motor 3, decanter type air trap device 2 comprises urceolus 4 and inner core 5, and urceolus 4 is sleeved on inner core 5 outsides, and urceolus 4 upper ends have exhaust port 7, and the middle part has air inlet liquid hole 6; Inner core 5 lower ends have inlet opening 8.
Oil well pump 1 is when work, gas-liquid mixture enters in the decanter type air trap device 2 by air inlet liquid hole 6, because Action of Gravity Field, liquid moves downward, enter oil well pump 1 from inlet opening 8, and gas is lighter, major part directly moves upward, enter casing annulus from exhaust port 7, and only have seldom a part in liquid enters oil well pump 1.Can reduce like this gas to the gas lock effect of pump, greatly improve pump efficiency, increase oil well output.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
