Shale gas, coal exploration drilling depth general all in hundreds of meters to thousands of rice, the test of sound wave deep hole be one important
Method, but because many borings have seepage, in the hole is anhydrous to wait liquid medium, and often many borings or hole section are due to seepage hydropenia
And cannot be carried out sonic test work, thus lose the chance obtaining borehole sonic data.
Application No. ZL201220272784.X utility model discloses a kind of acoustic detecting head of dry hole wall attaching device, including one
Individual acoustic emission probe and two acoustic receiver probes, acoustic emission probe is gone here and there using before and after wire with two acoustic receiver probes
Connection, it is characterized by respectively setting a shell fragment snap ring on acoustic emission probe and first acoustic receiver probe, each shell fragment snap ring
It is provided with rustless steel shell fragment, the lower section being located at each rustless steel shell fragment on wire respectively sets magnetic apparatus, magnetic apparatus pass through to connect
Cable connects 12V storage battery.Because probe can be attached on hole wall, carry out the sound wave energy of acoustic emission probe transmitting during sonic test
Propagate along hole wall rock mass and received by two acoustic receiver probes, thus reaching the quality feelings of test hole wall rock mass
Condition.This utility model simply solves the problems, such as that sonic probe is adherent good and bad, but unresolved main water coincidence problem,
In test, there are water and no water coincidence, the general difference times～decades of times of sonic propagation energy, no water coincidence majority of case cannot be complete
Become sonic test.
Application No. 200620163832.6 utility model discloses a kind of new dry hole acoustic wave testing probe, dry hole sound wave
Probe is made up of sonic probe and pressurization water pocket, and sonic probe is respectively arranged at two ends with water supply connector and exhaustor, in water supply connector
With water stopping trough is set respectively on the extexine of exhaustor, pressure (hydraulic) water cuff is contained in outside sonic probe and water supply connector and exhaustor.Open
The ratio of the first port footpath of the steam vent in exhaustor and end bore is 10: 1.Acoustic detecting head of dry hole of the present utility model can
Effectively couple with the hole wall of tested dry hole, locally create one kind in dry hole similar to the environment having couplant (as water).
The defect of this device mainly has the coupled problem of pressurization water pocket and dry hole wall, and sonic probe moves up and down inconvenient problem.On the one hand,
If pressure (hydraulic) water bag pressure power larger it is ensured that pressurization water pocket and dry hole wall efficient coupling, but now pressurization water pocket be difficult to mobile or no
Method moves；On the other hand, if pressure (hydraulic) water bag pressure power is less, pressurization water pocket can move, and now pressurize water pocket and dry hole wall coupling
Close poor, acoustic signals are weaker or difficult to accept is to acoustic signals, additionally, the method cannot operate in deep hole.
Utility model content
