Description
Technical field:
The present invention relates to used lift device, especially double-bridge oil-well pump in the oil recovery field, oil field.
Background technique:
Oil well pump is a kind of equipment that oil field operation generally uses, and at present, the oil well pump that use in the oil field has multiple, and each has different characteristics and function.But along with the deep exploitation in oil field, the numerous stripper well in oil field is increasing, and the difficulty of oil recovery strengthens.The present common oil well pump that uses, flow channels is narrow, and travelling valve ball size is less, and weight kicks the beam, its anti-paraffin blockage, wax card poor ability, pumping efficiency reduces, the poor reliability of especially working, the phase of being excused from a college course is short.
Summary of the invention:
In order to solve the existing problem that the oil well pump passage is long and narrow and pumping efficiency is low, the invention provides a kind of double-bridge oil-well pump, this double-bridge oil-well pump has Twin channel, and long service life is simple in structure, the characteristics that pumping efficiency is high.
Technological scheme of the present invention is: this double-bridge oil-well pump comprises the oil pipe that the pump barrel that is built-in with plunger and upper end are connected with joint, the oil pipe lower end links to each other with valve housing, the pump barrel upper end is connected step upper end in the joint by gland nut, the pump barrel lower end is connected on the interior annular boss of valve housing, the valve housing mider hole is built-in with the valve ball seat, last valve ball seat lower end is connected with down the valve ball seat, on, be equipped with respectively on the following valve ball seat, following valve ball, last valve ball upper end communicates with pump barrel ring cavity outward in the oil pipe by oil expulsion channel, the opposite side of following valve ball upper end valve housing has the oil input channel that communicates with pump barrel, and step axially had oily passage.
Pump barrel outer fixing in the such scheme has 4-8 centering ring, and centering ring axially has oil channel; Card has jump ring in following valve ball seat lower end valve housing (4) inner groovy.
The present invention has following beneficial effect: this double-bridge oil-well pump is owing to take such scheme, according to the pumping principle, adopted oil input channel and oil expulsion channel to separate, advance the mutual compact structure of oil extraction standing valve, advance oil drain passage thereby amplified, dwindle pump footpath but the valve aisle spare is constant, reduced clearance volume and increased discharge capacity, improved pumping efficiency, strengthened pump efficiency, be easy to the well-flushing sediment outflow, overcome paraffin blockage, wax card problem, prolonged working life.And have a disassembling, assembling and replacing that makes things convenient for valve, and simple in structure, reduced advantages such as seepage, practicality, help applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
1-pump barrel among the figure, 2-joint, 3-oil pipe, 4-valve housing, 5-step, 6-boss, the last valve ball seat of 7-, valve ball seat under the 8-, the last valve ball of 9-, valve ball under the 10-, 11-oil expulsion channel, 12-oil input channel, 13-jump ring, 14-centering ring.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, this double-bridge oil-well pump comprises the oil pipe 3 that the pump barrel 1 that is built-in with plunger and upper end are connected with joint 2, oil pipe 3 lower ends link to each other with valve housing 4, pump barrel 1 upper end is connected step 5 upper ends in the joint 2 by gland nut, pump barrel 1 lower end is connected on the valve housing 4 interior annular boss 6, pump barrel 1 outer fixing has 4-8 centering ring 14, and centering ring 14 axially has oil channel.Valve housing 4 mider holes are built-in with valve ball seat 7, last valve ball seat 7 lower ends are connected with down valve ball seat 8, card has jump ring 13 in following valve ball seat 8 lower end valve housings 4 inner groovies, upper and lower valve ball seat (7,8) be equipped with upper and lower valve ball (9,10) on respectively, last valve ball 9 upper ends communicate with pump barrels 1 ring cavity outward in the oil pipe 3 by oil expulsion channel 11, the opposite side of following valve ball 10 upper end valve housings 4 has the oil input channel 12 that communicates with pump barrel 1, and step 5 axially had oily passage.
During actual the use, joint 2 is linked to each other with tubing string, plunger links to each other with sucker rod, and valve housing 4 lower ends link to each other with screen casing.When plunger was up, last valve ball 9 was in closed condition, and following valve ball 10 moves up and opens oil inlet passage 12, and well liquid enters in the pump barrel 1; When plunger is descending, following valve ball 10 is closed, last valve ball 9 moves up and opens oil drain passage 11, and well liquid enters tubing string by the toroidal cavity of 1 of oil pipe 3 and pump barrel, the oily passage of mistake on the centering ring 14 and the oily passage of mistake on the step 5, reaches the purpose that well liquid is given rise to ground.According to the pumping principle, adopted oil input channel 12 and oil expulsion channel 11 to separate, not only advance the oil extraction Twin channel but also have the saturating oil of plunger to act on, advance oil extraction standing valve (9,10) compact structure mutually, advance oil drain passage (12 thereby amplified, 11), dwindle pump footpath but the valve aisle spare is constant, reduced clearance volume and increased discharge capacity, improved pumping efficiency, strengthened pump efficiency, be easy to the well-flushing sediment outflow, overcome paraffin blockage, wax card problem, prolonged working life.And have a disassembling, assembling and replacing that makes things convenient for valve, simple in structure, reduced advantages such as seepage, practicality.This double-bridge oil-well pump has Twin channel thus, and long service life is simple in structure, the characteristics that pumping efficiency is high.Help applying.
