Abstract: This paper discusses the basic principle of the sonic array transmittingsonde(SATS).The path of the sonic wave travelling is long in the long sp-acing sonic logging,thus,the sonic signal received is fairly weak anddose not satisfy the need requirement of logging in practice.According tothe principle of the phase shifting,the sonic energy distribution of the son-ic beam transmitted by SATS is in a best direction angle.Thus,the receivedsignal of head wave is increased to a great extent.

摘要： 本文论述了用地层的声波速度来自动控制阵列发射探头发射的声束偏转方向的基本原理.在测井过程中,这种阵列发射探头发射的波束能量分布能够始终处于最佳方向角,使接收的纵波首波信号大大增加,从而解决了由于源距长而造成的接收纵波首波信号过小的这一关键性问题.
