Abstract
The utility model relates to an efficient oil pump with large discharge capacity. The utility model is composed of a pump barrel, a plunger piston, a lower oil inlet valve, shunt valves, an oil outlet pull tube and a sealing barrel, wherein two shunt valves are installed in the upper part of the plunger piston, and the oil outlet pull tube is installed on the upper part of an upper shunt valve. The utility model is characterized in that an upper oil inlet valve is installed in the upper part of the pump barrel, and the sealing barrel is installed on the upper part of the upper inlet valve; internal seal sand prevention devices are respectively installed on both ends of the sealing barrel. The utility model has the advantages that the processes of twice oil suction and twice oil discharge can be accomplished in one reciprocating stroke, and thus, the liquid output of a single well is greatly raised; the bi-pass six-passage upper oil inlet valve enables oil passages inside and outside the pump to be smooth, the block coefficient of the pump and pump efficiency are high; a key part of the pump is protected, and the service life of the pump is extended; the utility model has the advantages of simple structure, low cost and convenient use.
Description
Affiliated field:
The utility model relates to a kind of pump, is used to have the efficient big discharge capacity oil well pump of bar mechanical oil recovery in particularly a kind of oil exploitation technology.
Background technique:
In mechanical oil production technology, when the formation pressure height, viscosity of crude is low, and oil well liquid-supplying is quite sufficient, so that when bigger conventional pumps does not satisfy requiring of lifting rate yet, adopt the submersible electric pump oil pumping usually.Submersible electric pump production fluid amount height, nearly 380,000 yuan of submersible electric pump initial investment, high by 60% than conventional pumps, and operating cost (electricity charge) is 400% of conventional pumps, so in some cases, though submersible electric pump is effective, but its economic benefit is not the best.Two kinds of double-acting pumps are arranged now, replacing submersible electric pump.A kind of double-acting pump, oiling valve filler opening is in the valve side on it, because filler opening place external diameter and internal surface of sleeve pipe gap are little, oil circuit is not smooth, so cause pump efficiency low; Another kind of, because last oiling valve filler opening is on valve top, oil circuit is unimpeded, so pump efficiency is higher, but this pump structure complexity, it takes the form of double pump series connection, increased the cost of an oil well pump, and pump length is near 16 meters, must dock at well head, during, time pump, the on-the-spot specific operation of the palpus pump professional workforce of factory, very inconvenient; In addition, owing to contain sand in the oil, can make very quick-wearing of the plunger of these two kinds of pumps and fuel-displaced trombone slide, wastage increases, and pump efficiency descends, and pump detection period shortens.
Summary of the invention:
The purpose of this utility model just be to provide a kind of cheaply, simple and practical efficient big discharge capacity oil well pump.
The technical solution of the utility model is: a kind of efficient big discharge capacity oil well pump is by pump barrel, plunger, and following oiling valve, diverter valve, fuel-displaced trombone slide, sealing drum is formed; In plunger upper part two diverter valves have been installed, fuel-displaced trombone slide have been installed on last diverter valve top; It is characterized in that: on pump barrel top oiling valve has been installed, sealing drum has been installed on last oiling valve top; Interior sealing sand control installation has been installed respectively at the sealing drum two ends.
Above-mentioned upward oiling valve is an oiling valve on the bilateral six tunnel, and bilateral is that the above and below of oil-feed oil circuit and valve is connected simultaneously; Six the road promptly adopt six oil-feed oil circuits, six cover valve balls, valve seat.
Sealing sand control structure is a quenching steel elastic sealing ring structure in above-mentioned, and it is made up of sealing case that is installed in the sealing drum end and the quenching steel elastic sealing ring that is installed in the band gap of sealing case inside; The internal diameter of seal ring and the external diameter of fuel-displaced trombone slide constitute no gap and cooperate.
The utility model has the advantages that: 1, adopt the double-action principle, (see figure 1) changes the process that reciprocal stroke of common oil well pump is only finished a strike the oil and an oil extraction, in a reciprocal stroke, can finish twice strike the oil and twice oil extraction, made full use of the mechanical output of pumping unit, improve the mechanical efficiency of pumping unit, increased substantially the production fluid amount of individual well; 2, with oiling valve on the bilateral six tunnel, (see figure 2) makes the outside oil circuit of pump unobstructed, and the runner of pump inside is than big, and oiling valve under the big runner of seven apertures in the human head, has improved the filling index of pump in twice strike the oil process of a reciprocal stroke, and pump efficiency is reached more than 85%; 3, adopt interior sealing sand control structure, made reservoir sand be difficult for entering in the friction pair of plunger and pump barrel, fuel-displaced trombone slide and sealing drum formation, protected the key position of pump, prolonged the working life of pump; 4, simple and reliable for structure, cost is low, and is easy to use, and it has saved the cost of the logical oil well pump of a Daepori and pull bar, is easy to assembling, rises, the pump operation need not the professional workforce of pump factory operation down.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is oiling valve and an interior sealing sand control structure on the bilateral six tunnel.
Fig. 3 is a quenching steel elastic sealing ring.
Embodiment:
As shown in Figure 1: efficient big discharge capacity oil well pump, mainly form by pump barrel 7, plunger 9, last oiling valve 5, following oiling valve 10, diverter valve 8, fuel-displaced trombone slide 6, sealing drum 4, interior sealing sand control structure 2.On plunger 9 tops two diverter valves 8 have been installed, fuel-displaced trombone slide 6 have been installed on last diverter valve top; On pump barrel 7 tops oiling valve 5 has been installed, sealing drum 4 has been installed on last oiling valve top; Interior sealing sand control structure has been installed respectively at sealing drum 4 two ends.
As shown in Figure 2: above-mentioned upward oiling valve is an oiling valve on the bilateral six tunnel, bilateral is that the above and below of oil-feed oil circuit and valve is connected simultaneously, and 11 is last filler opening among Fig. 2, and 12 are following filler opening, 13 is borehole wall sleeve pipe, and as we know from the figure: the above and below oil circuit of going up oiling valve is unobstructed; Six the road promptly adopt six oil-feed oil circuits, and six cover valve balls, valve seats 14 Duo 1～2 oil circuit than existing pump, and inner flow passage is than greatly.Like this, in the pumping process of pump, the inlet pressure of pump equals the pump intake pressure (liquid level is to the head of liquid at pump intake place) of pump all the time, and fluid sinks smoothly the filling index height of pump, pump efficiency height.
Sealing sand control structure 2 is quenching steel elastic sealing ring structure in above-mentioned.It is made up of 17,18 of the quenching steel elastic sealing rings of sealing case 15,16 that is installed in the sealing drum end and the band gap that is installed in sealing case inside.Its feature is: constitutes no gap with the internal diameter and the fuel-displaced trombone slide external diameter of ring and cooperates and realize sealing sand control, thus the purpose in the working life of realization prolongation pump.
