Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the existing spatial fusion method of 3D seismic data cannot realize the fusion of the first 3D seismic data and the second 3D seismic data when there is an energy difference between the first 3D seismic data and the second 3D seismic data. Amplitude-preserving processing and seamless fusion processing, which to some extent restrict the interpretability and practicability of 3D seismic data

Abstract

The invention discloses a spatial fusion method of three-dimensional seismic data. The method comprises: acquiring first three-dimensional seismic data in a specific area, the first three-dimensional seismic data including local abnormal data; The seismic data is subjected to energy normalization processing to obtain the third 3D seismic data and the fourth 3D seismic data. The second 3D seismic data is the data obtained after removing the local abnormal data from the first 3D seismic data; according to the local abnormal data, the second 3D seismic data is obtained. One, the second and the third spatial fusion factor; according to the third three-dimensional seismic data, the fourth three-dimensional seismic data, and the first, second and third spatial fusion factors, the fifth three-dimensional seismic data is obtained; for the fifth three-dimensional seismic data Energy recovery processing is performed to complete the spatial fusion of the first 3D seismic data and the second 3D seismic data. The invention can effectively improve the imaging quality, interpretability and practicality of three-dimensional seismic data.

Description

technical field [0001] The present invention relates to the technical field of geophysical exploration seismic data processing, in particular to a spatial fusion method of three-dimensional seismic data and a computer-readable storage medium, and provides a new method for the post-stack modification process link in geophysical exploration seismic data processing . Background technique [0002] As the world's major oil fields are increasingly demanding to reduce the risk of oil and gas exploration, 3D seismic exploration technology has become the mainstream technology in the field of seismic exploration because of its high migration imaging quality and resolution. As we all know, post-stack modification processing is a necessary part of conventional seismic data processing, which can not only improve the resolution and signal-to-noise ratio of 3D seismic data (because in post-stack modification processing, the The resolution and signal-to-noise ratio of seismic data are key ...
