深部地震资料的处理和解释方法
|
摘要
深部地震资料的处理类似于油气地震资料，但也有其自身的一些特点。在水平叠加处理前后，分别使用强有力的去噪和归位处理技术是获取高质量深部地震剖面的保证。在深地震时间剖面上，强能量条带的分布是大地构造格架的反映。综合测区重磁电等物化探资料进行解释，有利于提高解释精度和进一步探讨造山带的构造演化
Processing of deep seismic data is similar to that of oil and gas seismic data, but there are also some own features. Before and after horizontal stack processing, to use powerful reducing noise and migration processing methods is the guarantee of obtaining high quality deep seismic profiles. Distribution of strong energy zones on the deep seismic profiles is the reflection of the tectonic framework. Geophysical and geochemical exploration data including gravity, magnetic and electricity et.al data are comprehensively interpreted in favor of increasing interpretation accuracy and further discussing the structural evolution of orogenic belt.
