Description
One, technical field
The utility model relates to the equipment that cleans the outside near wellbore zone obstruction of pit shaft borehole, barrel and releasing pit shaft dirt, relates in particular to a kind of oil gas water well plug-removing device.
Two, background technology
Chinese patent 95213076.9 discloses a kind of sound wave broken down device, and its structure is to connect whistle seat bobbin on the blockages relieving fluid pipe, and 4 above whistler wave generators are installed on the seat bobbin outer wall of the whistle.Its purpose is with the obstruction under the energy eliminating oil well of whistler wave.But this broken down device exists the shortcoming and defect that the sound wave frequency band is narrow, power is little, effect is unsatisfactory.
Three, summary of the invention
The purpose of this utility model is the shortcoming or the deficiency that overcome or avoid existing in the above-mentioned prior art to provide a kind of oil gas water well plug-removing device that utilizes acoustic wave energy to remove the inside and outside formation blockage dirt of well wellbore.
Oil gas water well plug-removing device described in the utility model, comprise pipe nipple and nozzle, also comprise the supersonic generator that connects on the described pipe nipple, this supersonic generator is made of rectangular nozzle, resonant wedge whistle and Spring clip, the rectangular nozzle two ends link to each other with Spring clip with pipe nipple respectively, relevant position, resonant wedge whistle both sides is fixed with protruding axle, and protruding axle is with hole on the Spring clip and is slidingly matched, and resonant wedge whistle is installed on the Spring clip by protruding.
Wherein, described rectangular nozzle one end is the open circles tubulose, and the other end is the rectangular nozzle of rectangular aperture.Described resonant wedge whistle is the rectangle laminated structure that two ends have cutter, is installed on the Spring clip, and the one end edge of a knife faces the nozzle of rectangular nozzle.Described Spring clip is one to have the lath-shaped hardware of through hole, and resonant wedge whistle is installed on it by its protruding axle.
The utility model has following advantage compared with prior art:
1, power is powerful, operating distance is big, removing or plugging removal effect are good;
2, wide frequency range can be regulated arbitrarily in 1.5KHz～45KHz scope;
3, simple in structure, reliable in action, construction technology is simple, is suitable for popularization.
Four, description of drawings
Fig. 1 is the utility model structure cross-sectional schematic,
Fig. 2 is for to look schematic diagram by the structure left side of Fig. 1.
Five, the specific embodiment
Consult Fig. 1-Fig. 2, a kind of oil gas water well plug-removing device, comprise pipe nipple and nozzle, also comprise the supersonic generator that connects on the described pipe nipple, this supersonic generator is made of rectangular nozzle, resonant wedge whistle and Spring clip, and the rectangular nozzle two ends link to each other with Spring clip with pipe nipple respectively, and relevant position, resonant wedge whistle both sides is fixed with protruding axle, protruding axle is with hole on the Spring clip and is slidingly matched, and resonant wedge whistle is installed on the Spring clip by protruding.
Rectangular nozzle one end is the open circles tubulose, and the other end is the rectangular nozzle of rectangular aperture.Resonant wedge whistle is the rectangle laminated structure that two ends have cutter, is installed on the Spring clip 4, and the one end edge of a knife faces the nozzle of rectangular nozzle.Spring clip 4 is one to have the lath-shaped hardware of through hole, and resonant wedge whistle is installed on it by its protruding axle.
The course of work of the present utility model is: pipe nipple 1 is connected with tubing string, precalculated position in the lower going-into-well, the highly pressurised liquid that injects in the tubing string sprays on the edge of a knife of resonant wedge whistle 3 at a high speed from the slit-shaped spout 7 of rectangular nozzle 2, because the effect of eddy current, on the edge of a knife, form the phenomenon of periodically boosting, force and be fixed in protruding axle 5, resonant wedge whistle 3 on 6 is done flexural vibrations, produce strong synchronous vibration, and in liquid, produce powerful sound wave or ultrasonic wave, utilize the cavitation effect of ultrasonic wave generation, the intensification effect, mechanism such as acoustic streaming and miniflow is in order to remove shaft in wall, the obstruction dirt on stratum, the outside near wellbore zone of borehole or pit shaft.The distance that the jet velocity of adjustment liquid stream and resonant wedge whistle 3 and rectangular nozzle are 2 can obtain sound waves of different frequencies or ultrasonic wave.
Claims (4)
