摘要： 从非均匀角度利用实验方法研究了新疆准噶尔盆地东、西部油田的三组岩石样品：中基性火山岩、凝灰质角砾岩和砂泥岩, 测定了岩石样品在不同孔隙流体、温度和压力下不同方向的波速, 计算了衰减系数。本方法的特色是用二分量换能器测定波速, 提高了Ｓ波观测的可靠性和测试精度。

Abstract: Three groups of rock samples (neutral-basic volcanic rock, tuff-breccia, sandy shale) from eastern and western part of Junggar basin were experimentally examined in terms of heterogeneity, in which wave velocities of samples in different directions at different pore fluids, temperatures, and pressures were measured using two-component transducer and attenuation factor was calculated. This method can improve the reliability and accuracy of Swave measurement.
