Abstract
The utility model relates to an anti-sand thickening deep-pumping oil pump, belonging to a mechanical oil pumping device in the industrial petroleum exploitation, which is mainly used for the oil production of reciprocating rod pumps. The utility model mainly adds a liquid energy load-reduce device; a sealing section is arranged at the lower end of the device, and a spiracle is arranged between the section and a load-reduce piston; a liquid passing hole is arranged under the piston; a liquid passing hole is also arranged under a release assembly; the release assembly is connected with a sucker rod; and a release sleeve is arranged on one side of the load-reduce device. The anti-sand thickening deep-pumping oil pump is suitable for the requirement of large pump deep pumping technology due to the added liquid energy load-reduce device.
Description
One, technical field: the thickening deep oil well pump belongs to a kind of oil rig of petroleum industry exploitation, is mainly used in reciprocating type sucker rod pumping.
Two, background technique: sucker-rod pumping is one of traditional oil production method of World Oil Industry, and nearly 80% well is to use sucker rod pumping in the producing well in each oil field of China.And sucker rod to-and-fro motion drive plunger formula oil well pump is in the great majority.Along with the east China oil field enters the high moisture oil recovery stage in succession, it is the effective means that extract increases oil that big pump is taken out deeply.Employed conventional pumps of past, some is low for the pump barrel design strength, and the sucker rod load weighs when taking out deeply, and disconnected bar phenomenon is common, and the configuration of sand control card is perfect inadequately, is unfavorable for the requirement of the technology of taking out deeply at present.
Three, summary of the invention: the purpose of this utility model provides a kind of improved sand control card thickening deep oil well pump, and pump barrel thickness is increased, and reduces pump barrel deformation and prevents card piston phenomenon.In addition adjunction liquid can load-shedding equipment, the pump degree of depth is improved, satisfied and taken out needs deeply, original pump structure is like this: the upper end order of connection of pump is that tubing coupling connects portion's extension nipple and links to each other with the pump barrel box cupling, the interior erection column of pump barrel is traveling valve and lower travelling valve beyond the Great Wall, have the sand grid assembly to be contained in the lengthening tubing coupling in the lower end of this pump, the bottom extension nipple is threaded with the upper end tubing coupling with standing valve and thickening pump barrel and forms; Liquid can load-shedding equipment, and the top sucker rod is connected disjointed device, and the bottom is equipped with lightening piston, and is shaped on liquid pass hole, installs by the seal section sealing on this device top, and installs a side at this and be shaped on spiracle, so that produce lifting force during piston stroking upward.
Main beneficial effect of the present utility model is the intensity that has strengthened pump barrel, installs liquid energy load-shedding equipment additional, is fit to the requirement that big pump is taken out technology deeply.
Four, description of drawings: Fig. 1 is original pump body structure schematic representation
Fig. 2 is that liquid can the load-shedding equipment structural representation
Explain: 1, tubing coupling, 2, the top extension nipple, 3, the pump barrel box cupling, 4, upper travelling valve, 5, pump barrel, 6, plunger, 7, lower travelling valve, 8, the pump barrel box cupling, 9, bottom extension nipple, 10, standing valve, 11, the lengthening tubing coupling, 12, sand grid assembly, 13, sucker rod, 14, disjointed device discharges cover, 15, disjointed device, 16, filter screen, 17, seal section, 18, spiracle, 19, lightening piston, 20, liquid pass hole
Five, embodiment: with reference to Fig. 1, Fig. 2, the thickening deep oil well pump can be made up of by load-shedding equipment the pump housing of Fig. 1 and the liquid of Fig. 2.The tubing coupling 1 of Fig. 1 is connected with the top oil pipe, link to each other with pump barrel box cupling 3, pump barrel 5 by top extension nipple 2, pump barrel 5 inner plunger 6 upper and lower upper travelling valve 4 and the lower travelling valves 7 of being equipped with, pump barrel connects pump barrel box cupling 8 and bottom extension nipple 9 for 5 times, standing valve 10 is assemblied in the bottom extension nipple 9, the bottom extension nipple connects lengthening tubing coupling 11 for 9 times, its inner chamber dress sand grid assembly 12.Its liquid that increases installation newly can load-shedding equipment.As Fig. 2, be shaped on spiracle 18 between the last seal section 17 of this device and the lightening piston 19, and with the oil jacket annular space be same pressure system, lightening piston 19 lower ends are shaped on liquid pass hole 20, below disjointed device 15 above the piston 19, be shaped on filter screen 16, disjointed device 15 is connected with sucker rod 13, for realizing disconnecting disjointed device is housed and discharges cover 14.Each parts of sand control card thickening deep oil well pump all adopt public general part, and the requirement of no special shape, structure is a component invention.During work, produce uplift force during upstroke under the oil jacket differential pressure action, thereby alleviated the suspending point loading of pumping unit, reach the off-load purpose, because load descends, so equal strength of oil pump rod, under the equal pumping unit type condition, the following pump degree of depth can increase.
