Technical Field

[0001] The utility model relates to the technical field of oil well pump auxiliary equipment, in particular to a pump anti-leakage and anti-jamming device. Background Art

[0002] In the process of pumping oil in existing oil well pumps, sand and other debris will fall from the wellhead and the oil well pipe string above, and sand will be stuck in the pump, causing the pump to leak. Currently, there is no auxiliary part with sand prevention function installed on the upper part of the pump. Utility Model Content

[0003] The utility model aims to provide a pump anti-leakage and anti-stuck device for preventing sand from getting stuck in the upper part of an oil well, so as to solve the problems of sand getting stuck in the existing oil pumps and causing oil pump leakage.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pump anti-leakage and anti-stuck device, comprising an outer tube, an inner tube and a collector, the inner tube is connected to the outer tube through a lower connector, an opener is provided at the inner end of the inner tube, and the collector is the annular gap space formed by the inner tube and the outer tube.

[0005] Furthermore, the opener is fixed to the middle part of the outer tube through an opener frame.

[0006] Furthermore, an upper connector is fixedly provided on one end of the outer tube away from the inner tube.

[0007] Furthermore, the opener and closer is made of rubber, and a cross opening is arranged in the middle of the opener and closer.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model is installed on the upper part of the oil pump, can effectively prevent sand from falling into the oil pump to cause sand jam, has a simple structure and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the structure of the utility model.

[0011] In the above drawings, 1, upper connector; 2, outer tube; 3, opener and closer; 4, opener and closer frame; 5, inner tube; 6, lower connector; 7, collector. DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0013] like Figure 1As shown, the pump anti-leakage and anti-stuck device provided by the utility model is installed on the upper part of the oil pump, including an outer tube 2, an inner tube 5 and a collector 7. The inner tube 5 is connected to the outer tube 2 through a lower connector 6. An opener 3 is provided at the inner end of the inner tube 5. The collector 7 is an annular space formed by the inner tube 5 and the outer tube 2. The collector 7 is an annular space for storing oil residue. The lower connector 6 is a mounting structure for the inner tube 5 and the outer tube 2. The lower connector 6 is fixed at the upper oil extraction port of the oil pump.

[0014] In one embodiment, the opener 3 is fixed to the middle of the outer tube 2 through the opener frame 4. The opener 3 is made of rubber. A cross opening is provided on the top of the opener 3. The oil in the inner tube 5 enters the outer tube 2 through the cross opening of the opener 3. At the same time, the opener 3 also blocks the oil residue falling from the outer tube 2 to prevent it from entering the oil pump.

[0015] In one embodiment, an upper connector 1 is fixedly provided at one end of the outer tube 2 away from the inner tube 5 , and the upper connector 1 is connected to the oil pipe.

[0016] When the oil pump in the oil pipe is working, any debris falling in the well enters the utility model, passes through the upper connector 1, enters the inner part of the outer tube 2, is blocked by the opener and closer 3, and then enters the collector 7 formed by the inner tube 5 and the outer tube 2, which can effectively prevent various debris from entering the oil pump and prevent the pump from getting stuck; during the operation of the oil pump, mud, sand and other impurities that penetrate from the oil well formation are collected in the device collector; when the oil pump goes up, the opener and closer 3 is opened, and when the oil pump goes down or stops, the opener and closer 3 is closed, which effectively ensures that debris cannot enter the pump barrel. When the pump stops, the debris is separated from the pump barrel, and when the oil pump is started, the liquid flow carries the debris out of the well.

[0017] In the oil production process, when the oil pump is pumping oil, the sand falling from the upper wellhead and the oil pipe will be blocked by the opener and closeer 3 and deposited in the annular space between the outer pipe 2 and the inner pipe 5, which can effectively prevent the sand from falling into the oil pump and causing the problem of sand jam.
