The seismic dip attribute is regularly used to aid structural interpretation and is commonly adopted as a compulsory input for computing other seismic geometric attributes. One disadvantage of current dip computation algorithms is that interpreters compute the dip attribute time sample by time sample and do not consider the relationship between dip values of nearby samples. The classic convolution theory suggests one formation boundary should have the corresponding seismic event. However, the seismic wavelet always has a certain time duration. As a result, one formation boundary has a corresponding seismic event that consists of several time samples. Ideally, the time samples, which belong to the same boundary, should have approximately the same dip attributes. In this research, a sample by sample computation procedure is treated as an independent optimisation procedure. Then, simultaneously computing the seismic dip of time samples of one seismic trace can be regarded as a multi-objective optimisation procedure. The proposed method is based on analysing features of seismic waveform within user-defined windows. Considering that nearby time samples should have continuous dip values, we the dynamic time warping to simultaneously compute seismic reflectors’ dip values of a seismic trace. We applied our method to a field seismic data to demonstrate its effectiveness.

同时计算地震道的所有时间样本的 3D 倾角属性

地震倾角属性通常用于辅助构造解释，通常被用作计算其他地震几何属性的强制输入。当前倾角计算算法的一个缺点是解释器逐个时间样本计算倾角属性时间样本，而不考虑附近样本的倾角值之间的关系。经典的卷积理论认为一个地层边界应该有相应的地震事件。然而，地震子波总是具有一定的持续时间。结果，一个地层边界具有一个由多个时间样本组成的相应地震事件。理想情况下，属于同一边界的时间样本应该具有大致相同的倾角属性。在这项研究中，逐个样本的计算过程被视为一个独立的优化过程。然后，同时计算一个地震道的时间样本的地震倾角可以看作是一个多目标优化过程。所提出的方法基于分析用户定义窗口内的地震波形特征。考虑到附近的时间样本应该具有连续的倾角值，我们采用动态时间扭曲来同时计算地震道的地震反射体倾角值。我们将我们的方法应用于现场地震数据以证明其有效性。所提出的方法基于分析用户定义窗口内的地震波形特征。考虑到附近的时间样本应该具有连续的倾角值，我们采用动态时间扭曲来同时计算地震道的地震反射体倾角值。我们将我们的方法应用于现场地震数据以证明其有效性。所提出的方法基于分析用户定义窗口内的地震波形特征。考虑到附近的时间样本应该具有连续的倾角值，我们采用动态时间扭曲来同时计算地震道的地震反射体倾角值。我们将我们的方法应用于现场地震数据以证明其有效性。
