The paper introduces the principle of the seismic instantaneous attributes,and illustrates the features of karst in the seismic section,the instantaneous amplitude section,the instantaneous frequency section and the instantaneous phase section.
介绍地震瞬时属性分析技术的原理及处理方法,分别对岩溶在地震剖面、瞬时振幅剖面、瞬时频率剖面、瞬时相位剖面上的表现特征作了说明。
According to the attenuation characteristic of the seismic wave,we put forward a new amplitude gain method,which applying the instantaneous amplitude characteristic of Hilbert Transform,the distinguishing Method of the function extreme value and the curve fitting method to seismic amplitude gain,is called the self-adaptive amplitude gain.
根据地震振幅的衰减特性,提出了一种将希尔伯特变换瞬时振幅特性与函数极值判别法和曲线拟合法应用到地震振幅增益中的方法,称为自适应振幅增益。
Though the instantaneous amplitude has something correlated with the reservoir distribution, human error may be made when recognizing the instantaneous amplitude informa.
而瞬时振幅信息虽然与储层分布的关系密切,但抗噪能力较差,在断续问题上也容易造成人为误差。
