Description
One, technical field:
The present invention relates to the multi-functional well logging sound wave emission of a kind of rareearth super magnetostrictive focus.Belong to the geophysical well logging technical field.
Two, background technology:
Since the geophysical well logging technology was come out, the focus problem was puzzlement people's a technical barrier always.For a long time, engineering geophysics investigation and prospecting person is attempting to develop a kind of high-power well logging focus of easy and simple to handle, function admirable always, but obtains satisfied result.At present, be used to both at home and abroad the to log well equipment of focus has following a few class:
1, concerning well is arranged, general electric spark, electric detonator and the piezoelectric ultrasonic transducers etc. of adopting are as the well logging focus, but all there is big defective in these three kinds of focus, at first: electric spark, electric detonator are as the well logging focus, although transmission frequency is lower, energy can be used as big apart from CT tomography well logging between well and between well greatly, but timing uncertainty is arranged, uncontrollable, detection speed is slow, repeatability is bad, defectives such as emissive power shakiness can not satisfy the requirement of engineering detecting fully; Sparker source equipment heaviness, complicated operation, efficient is low, high pressure is dangerous, can not to use under the situation of no 220V dispatch from foreign news agency also be its fatal shortcoming; In addition, the electric detonator focus has not allowed in some countries and regions to use, because there is potential danger in it to testing staff's life security, and electric detonator can be blown up the borehole wall, cause collapse hole or plug-hole phenomenon, be a kind of destructive detection method, permanent boring obviously is not suitable for to needs for this.Secondly the piezoelectric ceramics acoustic wave transducer is as the well logging focus, although frequency height, survey timing standard, controlled, advantages such as detection speed fast, good reproducibility, but it has defectives such as energy little, fragile (insulation breakdown, stress rupture, heat damage, fatigure failure), aftershock are big, and it can only be as little spacing of single hole and the well logging of The Small Well spacing.
2, concerning water free well, generally be to adopt the flexible leather bag of piezoelectric ultrasonic transducer outsourcing, make leather bag and the incompatible transmission sound wave of borehole wall lotus root at leather bag inner high voltage water again, because the energy of piezoelectric ultrasonic transducer is little, add that the energy attenuation of sound wave between water, leather bag and the borehole wall is very big, cause the penetration range of sound wave short, can only make the small distance sonic detection, operation of equipment complexity in addition, efficient are very low.
3, in addition, Changjiang Engineering Geophysical Reconnaissance Academy (Wuhan), Changjiang Wa has developed soic wave transmitting energy converter equipment in the two-way pushing well of a kind of ultra-magnetic telescopic.This equipment is arranged two giant magnetostrictive rods up and down that in design the energy of compressional wave is very little in the emission sound wave, causes the amplitude of Mintrop wave very little; Two giant magnetostrictive rod two ends are lined with pad, and this will reduce Oscillation Amplitude widely, that is to say to have reduced emitted energy, cause penetration range littler; Four pull bars are difficult to guarantee two giant magnetostrictive rods, four end faces parallel up and down, also cannot say for sure to demonstrate,prove two giant magnetostrictive rod precompressed equilibrium of forces simultaneously, cause two giant magnetostrictive rods to rupture easily, have reduced the mission life of equipment; And this equipment can only be worked in well is arranged.
Three, summary of the invention:
The objective of the invention is at the advantage of above focus and the problem of existence, in conjunction with the rare earth ultra-magnetostriction material characteristics, develop a kind of not only can be used as big spacing, the well logging of little spacing single hole, greatly apart from CT imaging acoustic logging between sound wave between well and well, the rareearth super magnetostrictive multifunctional acoustic wave well logging focus that can in water and water free well are arranged, use simultaneously.
The objective of the invention is to realize by following technical scheme:
The multi-functional well logging sound wave emission of a kind of rareearth super magnetostrictive focus, have expelling plate, adjuster bar, coil former, coil cable, rareearth super magnetostrictive rod, balancing weight and wall rod, it is characterized in that: expelling plate be about two, two form rigid seal cydariform vibrating mass altogether; Be provided with between the expelling plate of the left and right sides and fix two expelling plates and regulate the adjusting screw(rod) that pressure is given at rareearth super magnetostrictive rod two ends; Be provided with cover pipe connector, cable cover(ing) and cable at the top of two expelling plates, the cover pipe connector is arranged on the periphery of cable cover(ing), and an end of cable is arranged in the cable cover(ing); In the inner chamber of the middle part of two expelling plates, be provided with coil former, coil and rareearth super magnetostrictive rod; Coil is arranged on the coil former, and lead-out wires of coil is connected with cable; The rareearth super magnetostrictive rod is horizontally installed in the coil former, and its two ends contact with left and right sides expelling plate respectively; Lower end at two expelling plates is provided with balancing weight.The present invention is fixed the position of two expelling plates by adjuster bar, regulate the precompression between rareearth super magnetostrictive rod and two expelling plates simultaneously, when in coil, passing through big transient current, the elongation of rareearth super magnetostrictive rod, to the impact that expelling plate produces nearly 200kg power, cause expelling plate vibration and produce the very sound wave of macro-energy.
The present invention's coupling has wall rod, and wall rod is provided with stay cord.The lifting of wall rod can guarantee combining closely of focus head and hole wall, guarantees the effective transmission of sound wave in dry hole and the loss of minimizing energy, guarantees effective transmission of shear wave simultaneously.
