| 摘 要： | 单孔波速测试的传统做法是在地面激振,在孔中接收,但该方法测试深度受限,测试精度较低,且对于海上钻孔来说,根本无法实现激振,故对于海洋工程钻孔的波速测试,则需要新技术来实现横波波速的获取。笔者介绍的悬挂式波速测井法将震源和检波器同时放入井孔中,摆脱了笨重的地面敲击震源,实现了波速测井设备的轻便化,由相距1 m的两个检波器接收S波的传播信号,为一发双收装置,利用传感器接收到震源传来的S波信号到达时间(初至)差,来确定钻孔所在处地层波速的一种新技术。该方法在南堡油田平台场址调查中发挥了重要作用,对120 m深的钻孔进行了横波测井,取得了良好的测试成果,为该工程项目提供了准确的剪切波速,为划分该场址的场地土类别发挥了重要作用。 |

| Abstract: | The traditional way of single bore wave testing is to make excitation on the ground and receive the signal in the bore,which causes the limitation of the test depth and reduce the test accuracy.In offshore drilling it can not achieve the recitation at all.Therefore,a new technique is required to obtain the shear wave for wave testing in offshore drilling.The hang wave logging method described in this paper puts both source and detectors into the borehole,thus getting rid of heavy ground source and realizing... |
| Keywords: | single bore wave testing hang wave logging tool shear wave velocity wave layering field soil type |
