With reference to Fig. 2, the piezoelectric ceramics of high-frequency emission transducer 21 in the emission array 2 and low frequencies transducer 22 employing thickness (tangentially) direction polarizations is rectangular to be spliced into pipe shape transmitting transducer or to adopt the ceramic pipe of 2 radial polarised to combine, use phased-array technique, control transponder pulse phase place, transmitted wave is superposeed with identical phase place at certain point in space, thereby obtain focusing effect.The quantity of high-frequency emission transducer 21 is 4, along the top that axially is distributed on emission array 2 of emission array 2, separates with short insulation spacer 23 each other; The length of short insulation spacer 23 is 3～5mm, is preferably 4mm.The quantity of low frequencies transducer 22 is 2, along the bottom that axially is distributed on emission array 2 of emission array 2, separates with short insulation spacer 25 each other; The length of short insulation spacer 25 is 3～5mm, is preferably 4mm; Separate with long insulation spacer 24 between high-frequency emission transducer 21 and the low frequencies transducer 22, the length of long insulation spacer 24 is 400～500mm, is 440～480mm preferably, and that best is 460～470mm.When emission, 4 high-frequency emission transducers 21 can adopt 1 emission, 2 emissions, 3 emissions or 4 emissions respectively, and the time delay of emission is adjustable.
With reference to Fig. 5, the receiving transducer 41 in the receiving array 4 adopts the annulus of 4 radial polarised to be in series, or adopts the ceramic pipe of 2 radial polarised to combine; The quantity of receiving transducer 41 is 4～8, and axially uniform along receiving array 4 separates with short insulation spacer 42 each other; The length of short insulation spacer 42 is 200～250mm, and that best is 220～230mm.
High-frequency emission transducer 21, low frequencies transducer 22 and receiving transducer 41 must be installed in the rubber balance oil sac and be sealed just and can use, and oil sac thickness is 2～3mm.Insulation spacer 23, insulation spacer 24, insulation spacer 25 and insulation spacer 42 can select for use the material of good insulation preformance to make, as teflon.
Referring to Fig. 3, Fig. 4, because the difference of required detection radial distance, require the spacing (distance between emission array 2 and the receiving array 4) of echo imaging logging device also different, so sound insulator 3 of the present invention have regular length sound insulator 31 and 32 two kinds of forms of variable-length sound insulator.Variable-length sound insulator 32 is combined by sound insulator top 38 and sound insulator bottom 39, can stretch between sound insulator top 38 and the sound insulator bottom 39, regulate the length of variable-length sound insulator 32, to satisfy the needs of different spacings, the adjusting length range of variable-length sound insulator 32 is 0～9m; Sound insulator top 38 adopts screw 37 to be connected with sound insulator bottom 39, also can adopt other connecting mode.The spacing range of adjustment of sound insulator 3 of the present invention is 3～13m.
Shell 35, housing 36 upper edge circumference at regular length sound insulator 31, variable-length sound insulator 32 have the staggered cutting 33 (seeing Fig. 3, Fig. 4) of vertical and horizontal, and to prolong acoustic wave propagation path, the attenuate sound wave energy reduces the sound wave amplitude; Can also adopt rubber and sound absorption ceramic to be combined as damping material 34 (see figure 6)s, effectively isolated sound wave is along the propagation of tool housing.
Use echo imaging logging device of the present invention, high-frequency emission transducer 21 in the excitation-emission array 2 and low frequencies transducer 22, the emission sound pulse, and incide the borehole wall with 2/3 times first critical angle, enter the stratum, if the near-borehole formation structure changes, be encapsulated in the wideband high-sensitivity receiving transducer 41 in the receiving array 4, just can receive the acoustic signals of reflection Different Strata structure, as the compressional wave (P ripple) on stratum, shear wave (S ripple), Stoneley wave (ST ripple) and longitudinal wave reflection ripple (PP ripple), transverse wave reflection ripple (SS ripple) is transformed wave (PS ripple) and horizontal vertical transformed wave (SP ripple) etc. in length and breadth.
Use the logging method of echo imaging logging device of the present invention, comprise that the reading of ripple signal data, ripple Signal Processing, reflected signal explain.After the reading of ripple signal data,, the ripple signal that reads is carried out following processing (see figure 7) in order to obtain more single reflection wave:
A. Signal Separation: mainly the ripple of the compressional wave in the waveform recording, shear wave and other band low-frequency disturbance composition is separated from the wave train.
A. when well external reflection interface and borehole wall angle less (0 °～20 °), can adopt the segmentation drawing method to separate compressional wave according to the difference on time of arrival; When well external reflection interface and borehole wall angle when big (＞20 °～＜90 °), because reflection line-ups shows as parallax, and the lineups of compressional wave keep perpendicular line substantially, can adopt median filter method to separate compressional wave.
B. utilize tangible time difference between shear wave and the reflection wave, adopt time segment compacting amplitude to separate shear wave.
Because the reflected signal amplitude is very little, and also may exist other interference waves in the period that reflected signal occurs, therefore still can't be used for actual treatment and explanation through the reflected signal after the initial gross separation.In order to improve the signal to noise ratio (S/N ratio) of data, also must carry out steps such as TEC time error correction, stack.
B. TEC time error correction: because the T-X curve of reflection wave is the hyperbolic curve form, therefore in 8 waveforms of each depth registration, there is regular hour difference between each road reflection wave, can't directly be poised for battle train wave shape and repeatedly superposes, therefore must at first eliminate these difference.TEC time error correction can adopt following formula usually:
In the formula: t
i---reflection wave time of arrival
x
i---spacing
V
(to)---time t
oCorresponding speed
C. signal stack: though obtained relative enhancing through the reflected signal amplitude that strengthens because the amplitude of signal own a little less than, so signal to noise ratio (S/N ratio) still is difficult to satisfy the subsequent treatment requirement.Because normally random appearance of undesired signal, therefore in order to improve signal to noise ratio (S/N ratio), compacting noise and other interference can reach the purpose that increases reflection wave signal intensity by signal is carried out overlap-add procedure.
D. wave field separation: on the waveform section after the stack, the boundary reflection signal is obviously strengthened, but is subjected to the influence of follow-up ripple of compressional wave and borehole wall reflected P-wave, deals with to still have big difficulty.The purpose of wave field separation is exactly in order to suppress interference, obtains the related parameter that has at well external reflection interface accurately.Utilization can adopt F-K filtering or τ-p filtering to suppress interference wave in the difference of speed between the different wave components on the waveform section.
The discrete form of τ-p conversion is:
Treatment step is as follows:
A. get the waveform of one section degree of depth and do τ-p direct transform, signal is transformed to τ-p territory from the x-t territory;
B. in τ-p territory to the undesired signal zone do compacting or the time become excision;
C. do τ-p inverse transformation, signal is recovered go back to the x-t territory.
In the waveform section after treatment,, can adopt corresponding disposal route to reduce its influence by further analysis to signal if also there is certain interference.
E. the time apart from conversion: what obtain from the waveform section is temporal information, by the time become distance (position) information of reflecting interface apart from conversion.
What the waveform of process overlap-add procedure comprised is temporal information, can reflect the form of reflecting interface, but can not accurately reflect information such as its position and angle.In order to obtain positional information more accurately, when the angle between reflection cross section and pit shaft is little, apart from conversion, convert time section to distance profile in the time of can adopting the average velocity formula to carry out, adopt conversion formula to be generally speaking:
In the formula: V
(to)Average velocity for correspondence.
When reflecting interface and well angle are big, use this formula and calculate and have obvious deviation, so can not use.
F. calculation of parameter: according to the position and the directional information in reflection cross section on the degree of depth (distance) or the velocity profile, calculate distance between this cross section and the well, extend interpretation parameters such as angle.Usually adopt the simple geometric method just can realize.
After the ripple information data is handled, obtain the reflection wave image, the reflection wave image is carried out quantitative test and geologic interpretation, step is as follows:
A. according to time of arrival and well azimuth, the interface that the inverting reflected wave information is reflected or the distance and the angle in crack of reflection wave.
B. according to the well track change information, judge the geology orientation in interface or crack.
C. figure is comprehensive with anisotropy figure, Stoneley wave stickogram, pigtail chart, microresistivity imaging that idol level SWAL is handled with reflection wave well logging imaging figure, describes stratal surface, crack, characteristic of fault in detail.
