In each change trend,with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content,the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix,which resulted in the measured data illustrating extremely different tendency.
样品在纵波速度-泊松比交汇图中表现出两种主要变化趋势,分别对应泥质与钙质胶结物的影响;在每个变化趋势中随泥质含量与钙质胶结物含量的增加,岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑,弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播,这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因,为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。
