Abstract

The interpretation of fault is essential for the oil and gas industries. This paper proposes an optimized patch-point-based approach for interpreting faults in a seismic data set using a convolutional neural network (CNN). We extract small patches of data for training and identify the fault patches. Next, we separately train seismic data points that are previously labeled as fault or non-fault. The strategy is to apply patch classification followed by analyzing fault patchs’ points to get the fault's location. We consider a mixture of synthetic and real data for training and as well as for testing. This method has used only the seismic amplitude values and has not considered any seismic attribute. We do normalization and quantization of seismic data to act as input to the CNN network, and the results show good accuracy when applied to synthetic and real data. GRAPHICAL ABSTRACT

基于局部点的CNN地震断层解释优化方法

断层的解释对于油气工业来说是至关重要的。本文提出了一种优化的基于补丁点的方法，利用卷积神经网络(CNN)来解释地震数据集中的断层。我们提取小块数据用于训练，并识别故障块。接下来，我们分别训练以前标记为故障或非故障的地震数据点。该方法首先对故障块进行分类，然后对故障块的点进行分析，得到故障的位置。我们考虑将合成数据和真实数据混合用于训练和测试。该方法仅使用地震振幅值，未考虑任何地震属性。对地震数据进行归一化和量化处理，作为CNN网络的输入，应用于合成数据和实际数据均显示出较好的精度。图形抽象

期刊介绍： Exploration Geophysics is published on behalf of the Australian Society of Exploration Geophysicists (ASEG), Society of Exploration Geophysics of Japan (SEGJ), and Korean Society of Earth and Exploration Geophysicists (KSEG). The journal presents significant case histories, advances in data interpretation, and theoretical developments resulting from original research in exploration and applied geophysics. Papers that may have implications for field practice in Australia, even if they report work from other continents, will be welcome. ´Exploration and applied geophysics´ will be interpreted broadly by the editors, so that geotechnical and environmental studies are by no means precluded. Papers are expected to be of a high standard. Exploration Geophysics uses an international pool of reviewers drawn from industry and academic authorities as selected by the editorial panel. The journal provides a common meeting ground for geophysicists active in either field studies or basic research.
