Description
Technical field
The present invention relates to technical field of geophysical exploration, particularly relate to Fossil fuel exploitation and exploration engineering field, tool
Body relates to a kind of dry hole sound wave water coincidence test device.
Background technology
The engineering utilizing boring to carry out testing in engineering investigation is a lot, but owing to many boring exists seepage, anhydrous in hole
Deng liquid medium, often many borings or hole section cannot be carried out sonic test work due to seepage hydropenia, thus lose acquisition
The chance of 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 before and after using wire with two acoustic receiver probes
Connection, is characterized by respectively to set a shell fragment snap ring, each shell fragment snap ring on acoustic emission probe and first acoustic receiver probe
Being provided with rustless steel shell fragment, the lower section being positioned at each rustless steel shell fragment on wire respectively sets a magnetic apparatus, and magnetic apparatus is by connecting
Cable connects 12V storage battery.Owing to probe can be attached on hole wall, carry out the sound wave energy that during sonic test, acoustic emission probe is launched
Propagate along hole wall rock mass and received by two acoustic receiver probes, thus reach to test the quality feelings of hole wall rock mass
Condition.This utility model simply solves the adherent good and bad problem of sonic probe, but unresolved main water coincidence problem.?
In test, there is water and without water coincidence, the general difference of sonic propagation energy times～decades of times.Majority of case without water coincidence cannot be complete
Become sonic test.
Application No. 200620163832.6 utility model discloses a kind of novel dry hole acoustic wave testing probe.Dry hole sound wave
Popping one's head in and be made up of sonic probe and pressurization water pocket, sonic probe is respectively arranged at two ends with water supply connector and exhaustor, in water supply connector
With set water stopping trough on the extexine of exhaustor respectively, pressure (hydraulic) water cuff is contained in outside sonic probe and water supply connector and exhaustor.Open
The first port footpath of the steam vent in exhaustor and the ratio of end bore are 10: 1.Acoustic detecting head of dry hole of the present utility model can
Effectively coupling with the hole wall of tested dry hole, in dry hole, local is created one and is similar to the environment of couplant (such 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 inconvenience problem.On the one hand,
If pressure (hydraulic) water bag pressure power is bigger, it is ensured that pressurization water pocket and dry hole wall efficient coupling, but now pressurization water pocket is difficult to mobile or nothing
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
Closing poor, acoustic signals is more weak or is difficult to receive acoustic signals.
Summary of the invention
It is desirable to provide a kind of dry hole sound wave water coincidence test device, to solve existing shale gas, coalfield sound wave is done
The problems such as the precision existing for the test of hole is low, error big, sonic probe moves up and down inconvenience, dry hole sonic prospecting cannot realize.
The present invention is achieved by following technical solution:
A kind of dry hole sound wave water coincidence test device, including an acoustic emission probe and two acoustic receiver probes, sound wave
Transmitting probe and two acoustic receiver probes are spaced connection successively by connecting band, connect band sidewall and are equipped with adherent spring,
The acoustic emission probe tip at top connects signal cable and water pipe, the top of acoustic emission probe and acoustic receiver probe and
Bottom is provided with some upper water jets being connected with water pipe and lower water jet respectively, and sound wave occurs probe top to be also equipped with spray
The mouth of a river switchs.
Described upper water jet and lower water jet are the most transversely arranged, and quantity is 4～5, and water jet is on adherent.
The invention has the beneficial effects as follows:
Compared with prior art, the dry hole sound wave water coincidence test device that the present invention provides, adopt in dry hole acoustic wave testing
By water spray coupling and adherent mode, reach sonic probe reach with hole wall good couple and test during signal to noise ratio higher
State, makes dry hole acoustic wave testing easily realize and meets the test request of existing acoustic wave apparatus.
