一、引言超声测井是一种新的地震測井法,它是利用超声波来研究小間隔內(1—2米)鈷井剖面岩层的物理机械性貭。近年来,由于石油探測事业发展的需要,这种方法在地球物理勘探和地球物理测井中受到了广泛的注意。根据超声測井的試驗和应用的結果看来,这种方法可以簡捷、經济、精确、詳細地測定出岩石的物理机械性貭(纵波和横波的波速,波的吸收系数等等)及其随深度的变化。超声測井在地震勘探工作中,能帮助解释人員正确地选取波速,井了解反射层的性貭,从而
I. INTRODUCTION Ultrasonic logging is a new method of seismic logging. It is the use of ultrasound to study the physical-mechanical properties of rock formations in a small interval (1-2 m) cobalt well. In recent years, due to the needs of the development of petroleum exploration, this method has received extensive attention in geophysical prospecting and geophysical well logging. According to the results of the test and application of the ultrasonic logging, this method can be used to determine the physical and mechanical properties of rock (velocity of wave and shear wave, absorption coefficient of wave, etc.) and its effect in a simple, economical, accurate and detailed way The depth of change. Ultrasound logging in seismic exploration, can help explain the correct choice of personnel speed wave, and understanding of the nature of the reflective layer, which
