摘要
不用充气囊或弹簧壁杆等附件设施 ,能在钻井中直接测得Vs是众多工程师的愿望。本文根据泥浆护壁孔中泥浆的力学特性 ,论述了在泥浆护壁钻井中可直接测得S波 ,并附测试实例
Based on the mechanic properties of slurry in drill holes it is suggested that the velocity of shear wave(Vs)can directly measured in a slurry filled drill hole without the tools such as the ball and the bar.The examples for the measurement of Vs are given.
