摘　　要：在声波测井仪器中,由单极子源辐射的全波列声波测井理论和技术已经得到了快速发展。但是全波列测井对纵横波的波形分离极为困难,处理方法非常复杂,而且在软地层中,岩石横波速度小于井内流体纵波声速,无法激发折射横波,从而无法测量地层横波速度,人们提出了利用多极源(偶极源和四极源)实现直接横波速度测井。文章介绍一种利用四极子源测量横波的声波测井仪的研制与应用,包括硬件设计、软件设计。Among sonic logging tools,the theory and technology of full-wave sonic logging radiated by a monopole source has been rapidly developed.However,full-wave logging is extremely difficult to separate the longitudinal and longitudinal waves,and the processing method is very complicated.Moreover,in soft formations,the rock shear wave velocity is less than the fluid longitudinal wave sound velocity in the well,and refracted shear waves cannot be excited,so the formation shear wave velocity cannot be measured.It is proposed to use multipole sources(dipole and quadrupole sources)to realize direct shear wave velocity logging.This article introduces the development and application of an acoustic logging tool using quadrupole source to measure shear waves,including hardware design and software design.
