Borehole PS Seismic Logging

- May 15, 2019-

Puas xav tau meej yog kev qov thiab cov qav dej ntws los ntawm lub sij hawm nyob rau hauv uncompacted ze ntawm qhov chaw sediment? Lub qhov dej ciav hlau PS seismic ncua kev soj ntsuam tau raug tsim los rau lub hom phiaj no thiab tuaj yeem muab cov kev ntsuas hauv PVC hauv tsev.

Los ntawm lawv tus kheej, cov lus qis qis qis qis tuaj yeem tsis zoo li cov khoom tseem ceeb tiam sis ua ke thiab nrog qhov kev ntsuam xyuas, cov pob zeb muaj zog xws li Poisson Ratio, Shear Modulus, Bulk Modulus thiab Bulk Compressibility.

Yav dhau los, cov ciaj ciam no yuav raug muab siv tas nrho cov kev soj ntsuam ntawm sonic sonic, tab sis nyob rau hauv uncompacted, nyob ze qhov chaw sediment lub shear nthwv dej yog qhov nyuaj heev. Kuj, lub full-size sonic xav tau kev qhib rau cov neeg mob qhib rau hauv qhov dej khov.
