Abstract
The utility model provides a downhole low-frequency vibration generator, which comprises a core shaft, a piston, a sleeve, a spring, a joint composition, which is characterized in that the core shaft passes through the sleeve to connect with the joint composition and the spring, the upper and the lower part of the spring are respectively connected with the piston and the joint, perforations are arranged on the core shaft, the piston and the sleeve and many rows of apopores are arranged on the sleeve. The utility model provides a downhole low-frequency vibration generator with wide application area, large power output, high energy efficiency, low frequency, long effective distance, small starting pressure and long-term continuous operation in water injection well for the field application of vibration oil production technology.
Description
Technical field
The utility model relates to the down-hole vibration source of vibrating oil production technology site operation, is specifically related to a kind of underground low-frequency vibration machine.
Background technology
Developed polytype ground and down-hole vibration source both at home and abroad, as the artificial earthquake adjustment vibrator, the underground ultrasonic wave producer, high frequency underwater sound porous generator, sheet type underwater acoustic transducer etc., but its principle, structure and the mode of action are different fully with the utility model.
The former Soviet Union once reported a kind of underground vibrating equipment, and its structural representation as shown in Figure 1.Its principle is that pressure acts on and compresses spring on the piston, and piston 2 moves downward opening part with spring 1, and fluid flows out, release pressure, and compressed spring elongation has formed pumping of piston, and then forms the pressure pulse vibration.Also has a spout hole 3 in the middle of the piston.
There is the shortcoming that sphere of action is little, power output is little in this underground vibrating equipment owing to have only two weep holes; Owing to have a spout hole in the middle of the piston, make that this plant capacity utilization rate is low; This device start pressure is bigger, and frequency is higher, and EFFECTIVE RANGE is short.
Summary of the invention
The purpose of this utility model is that the The field for the vibrating oil production technology provides one sphere of action is big, power output is big, capacity usage ratio is high, frequency is low, EFFECTIVE RANGE is far away, starting pressure is little, and down-hole vibration source---underground low-frequency vibration machine that can long-term continuous operation in water injection well.
The technical scheme that realizes the utility model purpose is a kind of underground low-frequency vibration machine, form by mandrel, piston, sleeve, spring, joint, it is characterized in that mandrel is connected with joint from middle the passing with spring of sleeve, the spring upper end is connected with piston, the lower end is connected with joint, has eyelet on mandrel, has eyelet on piston, have eyelet on sleeve, the sleeve upper end is furnished with the water holes of discharging more.
Advantage of the present utility model:
(1) simple in structure, mainly form starting of oscillation easily, working stability, reliable by mandrel, piston, sleeve and spring.
(2) utilize the lower pressure and the fluid of flow to get final product steady operation, can be used for long-term vibration water filling under the water injection well.
(3) adopt the uniform weep holes of many rows, have bigger sphere of action on vertically.
(4) impact of piston and sleeve can produce the mechanical oscillation effect.
(5) have lower vibration frequency, radially EFFECTIVE RANGE is far away.
(6) be furnished with interface, can a plurality ofly connect, power output is bigger.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is the utility model structural representation.
Specific embodiment
The utility model is made up of mandrel 4, piston 6, sleeve 5, spring 7, joint 8.The underground low-frequency vibration machine is connected on the oil pipe down to the down-hole target zone, with hydraulic anchor or packer setting on sleeve pipe, inject fluid on ground by oil pipe, fluid acts on the piston 6 by the eyelet on the mandrel 4, because weep hole is blocked by piston 6, the injection fluid is compressed, pressure progressively rises, thereby forces spring 7 compressions, and drive piston 6 moves downward, eyelet on moving to piston 6 is when eyelet on the sleeve 5 is communicated with, high-pressure fluid penetrates by eyelet, acts on target zone, and pressure discharges, spring 7 extends automatically by elasticity, drives piston 6 and moves upward.Piston 6 moves up and down so again and again, periodically opens or closes hydrophthalmia, thereby produces the pressure pulse vibration.
When piston 6 moves up and down, impingement sleeve, the vibration that produces certain frequency and energy, this vibration is passed to sleeve pipe by hydraulic anchor or packer, further target zone is produced the mechanical oscillation effect.Many discharge water hole (in figure do not mark) the intermittent jet of High-Pressure Water by arranging on the sleeve 5 of vibration source upper end produced powerful pressure pulse vibration, directly the stratum produced the vibration effect.
