跨孔波速测试技术在沉积地层中的应用

介绍跨孔波速测试方法和沉积地层的特点，并将跨孔方法应用于沉积地层中的测试研究。针对沉积地层分层多、有软弱夹层等特点，对跨孔的钻探、测斜以及孔间距、测点位置等一系列参数进行合理设计，并进行试验研究。结果表明跨孔波速测试适用于测试沉积地层中的夹层和较薄地层，并能获得可靠的结果。

Application of cross-hole wave velocity testing in sedimentary strata

The paper introduces the characteristics of cross-hole wave velocity testing and sedimentary strata and cross-hole wave velocity testing is applied to the sedimentary strata. For there are several strata inter-beded with soft stratum in the sedimentary strata area, reasonable parameters, drilling, deviation measuring, the space of boreholes and locations of testing points are designed to conduct the wave velocity test. The result shows that the cross-hole wave velocity testing can be applied to the inter-beded stratum and thin stratum of sedimentary strata and obtain reliable result.
