摘要
依托三维地震工程,在正演模拟的基础上,利用地震属性技术对压缩空气储能盐穴探测进行研究分析发现:振幅类属性对盐腔的整体刻画效果最好,甜点属性反映出盐腔的形态包络,顶部边界清晰;方差属性可以用来刻画盐腔的侧向边界.因此,采用以振幅类优势属性为主,其他属性(方差、瞬时频率等)为辅来综合确定盐腔的顶部以及侧向边界,同时结合人工交互综合分析对盐腔进行立体刻画,控制了盐腔的空间展布形态,取得了良好的地质效果.
Abstract
Based on 3D seismic project,this paper studied the underground salt cavern detection by using seismic attribute technology on the basis of forward modeling.The study reveals that the amplitude attribute has the best overall characterization effect on the salt cavity.The sweetness attribute reflects the shape envelope of salt cavity,especially the top boundary;the variance attribute can be used to characterize the lateral boundary of salt cavity.Therefore,the top and lateral boundaries of the salt cavity are determined comprehensively by using the dominant attributes of amplitude class supplemented by other attributes(variance,instantaneous frequency,etc.).Meanwhile,the 3D characterization of the salt cavity is carried out by combining the artificial interactive comprehensive analysis,and the spatial distribution of the salt cavity is controlled,and good geological results are obtained.
