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。
In the prediction of carbonate karst reservoirs, the “beaded” seismic reflection feature of karst caves is a very important identifier. The causes of the “Beaded” seismic reflections of the cave and how to highlight the cave features of the “Beaded” are discussed. Through the display processing and analogy analysis of the 3D preserved seismic data body and the three-dimensional conventional seismic data body of the Ordovician carbonate karst reservoir in the Tazhong area, it is concluded that the preserved amplitude seismic data are more conducive to karst caves Seismic reflection characteristics of the display and recognition.
