Embodiment Construction

[0061] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0062] like figure 1 Shown, a kind of seismic fault image processing method of the present invention, comprises the following steps:

[0063] The first step is to acquire the seismic fault image data set: obtain the seismic fault image data set, the seismic fault image data set includes linear geological fault structure images, curved geological fault structure images, linear and curved fault geological structure images, hierarchical geological structure images, etc.

[0064] The second step is to preprocess the seismic tomographic image dataset. like figure 2 and image 3 As shown, the seismic tomographic image data set is tangent in the X-T direction to form a data cube, and a 64*64*64 cube is set as a sliding window. Here, the...

Abstract

The invention relates to a seismic tomographic image processing method. Compared with the prior art, the defects that a seismic tomographic image is not clear and seismic tomographic interpretation isdifficult to carry out are overcome. The method comprises the following steps: obtaining a seismic tomographic image data set; preprocessing the seismic tomographic image data set; constructing a seismic tomographic image processing network; training a seismic tomographic image processing network; acquiring seismic tomographic image data to be processed; processing of seismic tomographic images.According to the method, geological data close to the nature are generated through a small amount of marked seismic data, the problem that the marked seismic data are insufficient is solved, unknown data are judged through the three-dimensional convolution integral network, and the seismic fault recognition efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of geological analysis, in particular to a seismic fault image processing method. Background technique [0002] The interpretation of seismic faults and horizons has always been an important issue in seismic structures. It simulates earthquake phenomena by imposing seismic waves on geological layers to form seismic fault images, thereby deconstructing seismic faults and horizons in 3D seismic images, which is beneficial to intuitively It has important application value in many industries such as construction and oil and gas exploration. [0003] In 2002, Peter Bakker proposed to use GPU-accelerated adaptive filters to realize fault interpretation of earthquakes, and divided the geological structure into linear structure, curved structure, and linear curved structure, and used different filters to realize seismic fault and horizon interpretation. However, there is a lack of pre-judgment means for seismic dat...
