溱潼凹陷帅垛茅山地区火山岩地震识别与描述

Seismic identification and description on volcanic rock in Shuiduo Maoshan area,Qintong Sag

通过地震剖面识别、振幅和相干剖面分析、地震属性的筛选分析和波阻抗反演等方法综合识别火山岩,地震识别结果和测井解释成果相吻合识别方法有效,并由此得到该区火山岩与火山口在阜宁组三段的平面分布图。

This article describes the following methods to identify volcanic rock:amplitude and coherent profile analysis,seismic profiles identification,seismic attribute screening analysis,and wave impedance inversion. The seismic identification and log interpretation got the same results,which proves the method is effective. The plane distribution map of volcano and caldera is obtained thereby.
