Seismic artifacts due to random and linear noises, low fold coverage, statics, and spatial aliasing are frequently affecting uncertainties in seismic interpretation. Several conventional methods, such as median filter, have been implemented to reduce random noises. However, this method can not be utilized for the area in which rich with stratigraphic features such as clinoforms and in the area with strong dips. We implemented layer-steered filter in order to attenuate random noises in this kind of situation. Layer-steered filter has ability to attenuate random noises but still respects to local dip events; therefore, the method provides better preservation of events and stratigraphics compared to other conventional methods such as median filter and dip-steered filter.

由于随机和线性噪声，低倍覆盖率，静力学和空间混叠引起的地震伪影经常影响地震解释中的不确定性。已经实现了几种常规方法，例如中值滤波器，以减少随机噪声。但是，这种方法不能用于地层特征丰富的区域（如斜形）和倾角较大的区域。为了降低这种情况下的随机噪声，我们实施了层控滤波器。层控滤波器具有衰减随机噪声的能力，但仍会考虑局部浸入事件；因此，与其他常规方法（例如中值过滤器和浸入转向过滤器）相比，该方法可更好地保留事件和地层。
