While-drilling down-hole measurement.Adopt subsurface tools such as MWD, LWD, measure the physical and mechanical parameter on stratum while creeping into.
Two kinds of technology of rock core test and well logging interpretation only just can be carried out formation evaluation under the situation that obtains rock core information and well-log information after the finishing drilling of a bite well.On-the-spot test can be carried out in drilling well midway, but because duty cycle is long, difficulty is big, expense is high, generally can only obtain the stratigraphic information of a point or several points.Though While-drilling down-hole measurement can be obtained formation information in real time, continuously, because of instrument costliness, complex process, measurement cost height, rig-site utilization is less, generally only is used for emphasis well highly difficult, that technology is special.
Summary of the invention: the purpose of this utility model is that a kind of landwaste acoustic velocity measurement mechanism will be provided, with the well drilling detritus that obtains easily, the source is sufficient as tested object, physical and mechanical parameter, pressure characteristic parameter and the terrestrial stress data of coming the quantitative Analysis subterranean strata by the acoustic velocity of measuring landwaste.
The purpose of this utility model is achieved in that landwaste acoustic velocity measurement mechanism is by supersonic reflectoscope, compressional wave and shear wave probe, fixedly pressue device, acoustic transmission line etc. are partly formed.Supersonic reflectoscope comprises acoustic pinger, sound pulse receiver and oscillograph; Each is made up of compressional wave and shear wave probe a transmitting probe and a receiving transducer; Fixedly pressue device partly is made up of base, guide rail, weight, probe bearing etc., is used for supporting, fixing and set upright sonic probe, apply certain pressure to sonic probe, and it is contacted well with the landwaste surface.
This method is not subjected to the restriction of rock core and well-log information, has remedied the deficiency of existing method, and can estimate the character of subterranean strata according to the landwaste acoustic wave character in real time, continuously, it is simple to have instrument, easy to carry, expense is cheap, and is simple to operation, the measuring accuracy advantages of higher.
Description of drawings: Fig. 1 is the structural representation of the landwaste acoustic velocity measurement mechanism that proposes according to the utility model.
Among the figure, the 1-supersonic reflectoscope, the 2-acoustic transmission line, the 3-transmitting probe, the 4-receiving transducer, 5-landwaste to be measured, 6-base, 7-guide rail, 8-increase the weight of soon, the 9-bearing of popping one's head in.
Embodiment: describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, landwaste acoustic velocity proving installation is by supersonic reflectoscope 1, compressional wave and shear wave probe, fixedly pressue device, acoustic transmission line 2 etc. are partly formed.
