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 constant voltage water spray coupling deep hole test device.
Background technology
Shale gas, coal exploration drilling depth are general the most all in hundreds of meters to thousands of rice, the test of sound wave deep hole be one important
Method, but owing to many boring exists seepage, the anhydrous liquid medium that waits in hole, 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 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, having water with without water coincidence, the general difference of sonic propagation energy again～decades of times, cannot be complete without water coincidence majority of case
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, additionally, the method cannot operate in deep hole.
Summary of the invention
It is desirable to provide a kind of dry hole sound wave constant voltage water spray coupling deep hole test device, with solve existing shale gas,
Precision existing for the sound wave deep hole test of coalfield is low, error big, sonic probe moves up and down inconvenience, deep hole sonic prospecting cannot be real
The problem such as now.
The present invention is achieved by following technical solution:
A kind of dry hole sound wave constant voltage water spray coupling deep hole test device, including acoustic emission probe and two acoustic receiver
Probe, acoustic emission probe and two acoustic receiver probes are spaced connection successively by connecting band, connect band sidewall and are equipped with patch
Wall spring, the acoustic emission probe tip of top connects signal cable and water pipe, and water pipe is provided with hydrostat, sound
Ripple transmitting probe is equipped with some water jets being connected with water pipe with acoustic receiver probe top.
Spacing between described hydrostat and acoustic emission probe is 2m～5m.
Described hydrostat top is provided with osculum.
Described water jet is 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 constant voltage water spray coupling deep hole test device that the present invention provides, at dry hole sound
The test of depth of convolution hole uses the mode of water spray and hydraulic pressure adherent, permanent regulation, reaches sonic probe and reach good coupling with hole wall
The state higher with signal to noise ratio during test, makes the test of dry hole sound wave deep hole easily realize and meet the test of existing acoustic wave apparatus
Requirement.
