摘要:
单点数字检波器采集优势不仅依赖其固有特性,还与地震信号传播过程中的吸收衰减作用有关,因此其应用效果与工区近地表的地震地质条件密切相关。WLZ地区近地表火成岩广泛发育,分布表现为多期、多套、多产状的特点,物性表现为低速孔隙状、中高速-高速致密状火成岩,对高频信号产生了较大的吸收衰减作用,因此数字检波器的性能特点在近地表存在复杂多类型火成岩的区域难以充分体现。
Abstract:
The acquisition advantage of single digital geophone is not only relied on its inherent characteristics, but also related to absorption attenuation during seismic signal transmission. Therefore, its application effect is closely related to the seismic geological conditions near the surface of the work area. The near-surface igneous rocks in WLZ region are widely developed.Their distribution is characterized by multiple periods, multiple sets and high productivity, with physical properties of low-speed porosity, medium-high speed and high-speed compact igneous rocks, which have a larger absorption attenuation effect on high frequency signal. Therefore, it is difficult to fully embody the performance characteristics of digital geophone in near-surface existing complex kinds of igneous rock area.
