Description
Technical field
The utility model belongs to oil and gas rock mechanics field, is specifically related to a kind of servicing unit quick and precisely detecting rock core velocity of wave in length and breadth.
Background technology
The p-and s-wave velocity of rock is the base attribute of rock, the parameter such as the dynamic modulus of elasticity and dynamic Poisson's ratio of rock can be obtained by it, the petroleum industry that this buries deeply for oil gas, geological condition is complicated, determines that the exploration of P-and S-wave velocity to oil gas field of rock, the evaluation of mining site, normal drilling operation hold the balance exactly.Through investigation, the ultimate principle at present for laboratory core wave speed measurement is in length and breadth mostly identical, but measuring method differs and all without any aided measurement device, method conventional is at present placed in by rock core between two probes, and make its close contact.Due to the transport properties of ripple in length and breadth, longitudinal wave velocity measurement is easier to, the measurement of transverse wave speed is then very difficult, keeps motionless and rotates rock core, now will find the thick-and-thin ripple of waveform on oscillograph so specially require upper and lower relative probe position when transverse wave speed is measured.This is very inconvenient to operating under depending merely on artificial situation, and is also difficult to reach above-mentioned requirement of experiment, makes resultant error very large.In addition, this measuring process requires high to rock core, and level is wanted at rock core two ends, can not have inclination angle; For the research of laboratory experiment of effective stress on rock core velocity of wave impact in length and breadth, because the current device that there is no rock core applies stress also cannot carry out.Therefore, need according to wave property in length and breadth and develop corresponding servicing unit, for the laboratory core measurement of velocity of wave and experimental study in length and breadth.
Summary of the invention
The purpose of this utility model is: provide a kind of servicing unit quick and precisely detecting rock core velocity of wave in length and breadth, meet wave speed measurement requirement in length and breadth, can exert pressure to study the impact of effective stress on velocity of wave in length and breadth to rock core simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of servicing unit quick and precisely detecting rock core velocity of wave in length and breadth, the feature of this servicing unit is, its structure comprises table, spinning screw rod, upper cover, pressure transducer, bulb, probe, rock core, shaft collar, base in number pressure, bulb is positioned at below spinning screw rod, bulb rectangular structure has shaft collar, probe, rock core, probe, shaft collar from top to bottom successively, and rock core is positioned at upper and lower two probe centre positions.Described base is positioned at package unit bottom, and the base left and right sides is connected, for fixed support column with support post lower end, two, left and right respectively.Described spinning screw rod is positioned at upper cover centre position, its spiro rod length is 7cm, maximumly exert pressure as 10kN, it can apply different pressures to different length rock core, keep keeping close contact between rock core and probe, pressure signal transmission shown in number pressure by the pressure transducer between spinning screw rod and bulb, in described number pressure, table is installed on the top of Left-side support column, monitoring applies pressure size, and wherein the maximum pressure-bearing of pressure transducer is 50Mpa.Described bulb is positioned in the middle of pressure transducer and probe, and mother bulb head is positioned at above public bulb, and therefore bulb can have the rock core of certain inclination to measure to end face, keeps rock core axis to overlap all the time with device axis.Described shaft collar and probe respectively have two respectively, containing 3 knob screws and a groove in described shaft collar, therefore shaft collar can fix the probe of different size, described probe can be changed on request pressurized probe and pressurized probe, use not pressurized probe time measure velocity of wave in length and breadth, use pressurized probe can study the impact of effective stress on velocity of wave in length and breadth.Two support post middle parts in two ends and left and right of described upper cover are connected, and upper cover is fixed on support post by fixed knob, upper cover can move up and down, support post length is 30cm, therefore upper cover can have enough move up and down space by move up and down meet different length rock core measure requirement, servicing unit overcomes the deficiency of existing laboratory core wave speed measurement device in length and breadth, and meet the requirement of experiment of wave speed measurement difference in length and breadth, experimental data accurately and reliably.
The beneficial effects of the utility model:
As can be seen from above-mentioned technical scheme, the utility model provides a kind of servicing unit quick and precisely detecting rock core velocity of wave in length and breadth, this apparatus structure is simple, easy to operate, the requirement of experiment of wave speed measurement difference in length and breadth can be met, increased the purposes scope of existing equipment by this device, experimental error is also reduced greatly.
