WZG-24 Seismograph Rau Borehole PS Logging

- Mar 20, 2019-

Micro-logging yog ua raws li ib los yog ntau dua qhov dej kis tau los ntawm cov cheeb tsam qis thiab zeeg. Kev xa tawm tsis muaj sau los ntawm kev ua kom zoo (los yog txais tos), txais tos hauv av (los yog excitation), raws li kev sib kis yoj. Ib txoj kev los ntawm kev kawm nyob ze ntawm cov qauv ntawm thawj lub sij hawm tuaj txog.


Lub seev cev ntawm seismic PS nkag tau siv hom kev ua kom tau zoo thiab hauv av tau txais. Qhov tob ntawm qhov kev sim zoo yog 15 m, ntawm qhov kev cia siab luv ntawm 0.5 ~ 12.5 m yog 0.5 m, thiab qhov pib luv ntawm 13 ~ 15 m yog 1 m. 1 Ua kom tau ceev nrooj, thaum lub sij hawm kom ntseeg tau tias qhov kev sib tsoo yog kev zoo siab hauv dej.


Txais siv WZG-24 engineering seismograph, qhov kev nce qib kev ua ntej yog 12 dB, kev sampling luv yog 0.2 ms, qhov sau ntev yog 500 ms; tus PS-38 tus ntes tau ntsuas yog 12 qhov sib npaug, thiab 1-5 zoo sib nraus yog 1 m, 6 Qhov sib tw 12-zoo yog 2 m, raws li qhia hauv qab no.

Cov tshuaj tua kab mob me me ntawm qhov dej zoo yog qhov yooj yim nyeem thaum pib thiab pib. Tus txhais lus tau raug qhia nyob hauv daim duab 11: qhov qis tshaj tawm muaj txheej thickness ntawm 2.66 m thiab tshaj tawm yog 431 m / s; cov txheej qis muaj ib qhov thickness ntawm 4.32 m thiab tus tshaj tawm ntawm 989 m / s; qhov siab tshaj tawm txheej 1 muaj qhov thickness ntawm 4.68 m thiab tus tshaj tawm ntawm 2 804 m. / s; Kev kub ceev txheej 2 ceev yog 4 137 m / s.
