| 摘 要： | 通南巴工区是油气聚集的有利区带,区内岩性复杂多变,存在多个强反射界面。同时受强烈挤压作用,断层破碎带发育。破碎带和浅层强反射界面使地震能量难以下传,对地震波产生很强的能量屏蔽作用,大大降低灰岩区资料品质。通过对工区内地震资料品质分布特征分析,对资料品质产生重要影响的几种能量屏蔽作用进行分析,并提出解决方案。

| Abstract: | Tongnanba Work Area is an area favorable for the aggregation of oil gas.In this area,the lithology is complicated and polytropic,and many strong reflection interfaces can be found.The crush zone develops under a forceful extrusion.The crush zone and the shallow layer strong reflection interfaces make it difficult for the seismic energy to pass on.Therefore,the seismic wave will be subject to a strong energy shielding effect,and the quality of data on limestone pavement will be signifi- cantly lowered.The quality distribution characteristics of seismic data in this area and the energy shielding effects which will greatly impact the data quality are an- alyzed,and some countermeasures are put forward. |
