摘要
在碳酸盐岩岩溶储层预测中,溶洞的"串珠状"地震反射特征是一项很重要的识别标志。对溶洞的"串珠状"地震反射成因和如何突出溶洞"串珠状"的显示特征进行了探讨。通过对塔中地区奥陶系碳酸盐岩岩溶储层三维保幅地震数据体和三维常规地震数据体分别进行显示处理和类比分析,最终认为保幅地震数据更有利于溶洞"串珠状"地震反射特征的显示与识别。
The beads-shaped seismic reflection characteristic of karst cave is avery important identification mark in the prediction of carbonate karst reservoirs.In this paper,the origin of bead-shaped seismic reflection was discussed,and then,how to highlight the beads-shaped seismic indicating characteristic of karst cave was referred.It is proved that seismic dataof preserved amplitudes are more beneficial to the display and identification of bead-shaped seismic refection characteristic of Ordovician carbonate karst caves,with acomparison between the 3-D preserved amplitudes seismic dataand 3-D conventional seismic datain identification of karst caves in Tazhong area.
