Problems solved by technology

[0005] Embodiments of the present application provide a method, device, equipment, and medium for extracting karst cave geological bodies based on seismic data, which are used to solve the problem that the existing method for extracting karst cave geological bodies based on seismic data needs to manually set a threshold. For seismic data greater than the threshold, the corresponding The location and type of the cave are determined as the location and type of the cave, which leads to the inaccurate problem of the geological body of the cave

Abstract

The invention provides a karst cave geologic body extraction method and device based on seismic data, equipment and a medium, and the method comprises the steps: inputting the seismic data into a deep learning U-shaped neural network, obtaining a probability matrix, generating a karst cave geologic body image according to the probability matrix, and enabling a user to check the image to determine the position and type of a karst cave. According to the scheme, the seismic data are processed through the deep learning U-shaped neural network, and the accuracy of the obtained karst cave geologic body is effectively improved.

Description

technical field [0001] The present application relates to the field of oil and gas geophysical exploration, and in particular, to a method, device, equipment and medium for extracting karst cave geological bodies based on seismic data. Background technique [0002] Oil and natural gas are important resources of the country and the lifeblood of the country's economic development. For oil and gas exploration, there are many karst cave bodies underground, and it is very important to be able to identify the karst cave geological bodies. With the rapid development of science and technology, there are more and more methods for determining the geological body of karst caves. [0003] In the prior art, sampling points are usually arranged on the ground, seismic waves are artificially excited, and the location and type of karst caves are obtained by analyzing the data collected at the sampling points. Since the value of the karst cave geological body in the seismic data is larger t...
