The experimental provision of set implements above-mentioned test method, so that rocks acoustic velocity measurement accuracy is high, meets full cement rock in high pressure
Rocks acoustic velocity test request under drainage condition, and the complete of rock sample can be protected.
A kind of embodiment according to the present invention, in step S1, rock sample is the cylindrical sample of standard, is used first
The length L of vernier caliper measurement rock sample0, then rock sample is put into the center in sealing rubber cover in the dry state
Position, by the full water clamp assemblies being made of netted separation layer, channel guide sleeve, fixed ring be packed into sealing rubber cover, make it is netted every
Absciss layer is tightly attached to two end faces of sample, and then whole be put into carries out vacuumizing full water in the sink of sealing.Wherein, seal rubber
Set is the elastic rubber sleeve an of both ends open, the outer rim of fixed ring and the dynamic contact of the inner wall of rubber sleeve and sealing is adapted to, Gu
Determine to be connected with netted separation layer in the inner circle of ring, micropore is covered on netted separation layer, cylindricality circular tube shaped is terminated with outside fixed ring
Channel guide sleeve, channel guide sleeve inner end are adapted to fixed ring and netted separation layer, and inner end outer peripheral edge is moved with the inner wall of rubber sleeve and contacted
And sealing adaptation, outer end are that worn-out mouth forms channel.Under vacuum-pumping conditions, rock sample air is extracted, and sample is inside and outside to be formed
Pressure difference, water can enter sample interior by netted separation layer out of channel guide sleeve, and whole process continues to sample external and internal pressure
Until balance, rock sample is fully saturated at this time, and full water clamp assemblies are taken out from sealing rubber cover.In water saturation process
In, due to the constraint of sealing rubber cover and netted separation layer, it is ensured that rock sample does not expand outwardly, and ensure that rock sample
Structure and external size constancy.
Further, transmitting probe and receiving transducer are inserted into the both ends of the sealing rubber cover equipped with saturated rock sample respectively
The probe base of opening, transmitting probe and receiving transducer is affixed in sealing rubber cover and respectively with two end faces of rock sample
It closes.The probe base of transmitting probe and receiving transducer and sample contact one end equipped with groove, and the other end is equipped with aperture and groove phase
