Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
The down-hole waterpower external excited oscillation supercharger structure figure that accompanying drawing provides for the utility model.
Among the figure 1. with the drill string junction button, 2. pair circular arc type entrance channel, 3. intensifier body, 4. fluid inlet nozzle, 5. its swashs hole, 6. resonance pressurized chamber, 7. chamber fluid feedback wall, 8. the fluid issuing nozzle 9. connects with drill bit and detains or the rock crushing tool that establishes one's own system.
The specific embodiment
When the fluid with certain speed by drill string in empty 1 through entrance channel 2 is injected resonance pressurized chamber 6 from inlet nozzle 4 after, regional in chamber upstream because strong the entrainmenting of turbulent jet, its swashs pressure disturbance effect to add its sharp hole 5 introducing annular fluid, realizes the resonance supercharging in chamber 6.Its swashs hole 5 be porous, and resonance pressurized chamber 6 is a cylinder, and chamber fluid is fed back wall 7 and cut body for many curved surfaces.Inlet nozzle 4 and outlet nozzle 8 are changeable type cylinder nozzles, and inlet nozzle also can add 1～2 attached nozzle of minor diameter.Down-hole external excited oscillation supercharging mainly relies on following three kinds of modes of action:
(1) effect of the entrainmenting jet entrainment effect of jet can be divided into five kinds of situations by its mode; 1. intermolecular capabilities exchange; 2. ability, material, the momentum conversion that causes owing to concentration, temperature difference; 3. the exchange that causes owing to turbulent diffusion, viscous diffusion etc.; 4. owing to sticky shearing power, jet drives ambient medium, makes near the original static or low velocity fluid of jet beam outer surface obtain speed; The speed of the inner near surface of simultaneously original jet reduces, the serialization of tangential velocity discontinuity surface, thus the jet external boundary is outwards expanded; 5. ambient medium is involved in jet beam inside by the large-scale structure of jet (big whirlpool).Preceding 3 kinds of caused exchanges and transmit lessly, back two kinds of situations then are topmost action modes.
In this resonant cavity, mobile the belong to submerged non-free jet of jet in chamber, and by following nozzle impact walls with after chamber inner wall rubs mutually, can form the vortex of more different scale in the chamber.Therefore, 5. the kind situation be to entrainment topmost factor.When frequency was moderate, these whirlpools were just enough big, when it arrives down nozzle, and the strong pressure transient of collision extruding generation with it.In collision process, big whirlpool leads out the annular fluid that is involved in wherein on the one hand, and the surrounding fluid in its downstream is pushed out; Form vacuum on the other hand at its upstream, the outer fluid (annular fluid) of resonant cavity is introduced in the chamber, push down nozzle to by sucking in of its upstream with the contiguous big scrollwork in this whirlpool.Such loop cycle is continuous.Just formed the external excited oscillation pulsing jet.
(2) after the formation effect vibration of resonant cavity feedback negative pressuren zone forms, produce the pressure disturbance ripple through collision, this pressure disturbance ripple upstream feeds back to the initially-separate district with high speed, thereby causes that the Disengagement zone produces new vorticity pulsation, and the panting action of vorticity has and ambient medium blending and ability.If the new vorticity that pressure disturbance produces can satisfy certain amplification condition, will constantly produce vorticity pulsation (vortex) in the initially-separate district, these vorticity pulsation major parts are in low-pressure state, thereby in this zone, form the certain negative pressure zone, and has the ability that the injection surrounding fluid enters the main flow core space.
(3) its sharp acting on the boundary layer of jet of annular fluid pressure, jet has tangible low-pressure area (the entrainmenting property of jet), simultaneously because the feedback effect of resonator chamber forms the certain negative pressure zone near the close top nozzle of chamber.Therefore in the little duct of self-priming of linking up chamber and annular space, annular fluid will flow in the chamber that is in low pressure or negative pressure by this duct under its head of liquid effect, like this, because the introducing of annular fluid, increase the quality of chamber fluid, strengthened the momentum and the percussion of outlet jet.The effect of annular fluid liquid column hydrostatic pressure just is equivalent to continual its sharp jet source that adds.Its characteristics are exactly that resonator chamber does not add its excitation device, and only with the liquid column hydrostatic pressure of annular fluid as it swash the source.
