Problems solved by technology

Therefore, this multi-dimensional seismic attribute fusion method improves the quality of the fuzzy area after fusion by reducing the data quality of the original seismic attribute clear area to obtain a fusion result with "clear" targets, which makes the actual fusion result deviate from the ideal fusion result. Causes the loss of some edge information in the target geological body, which cannot better reflect the characteristics of the geological target

Abstract

The embodiment of the invention provides a multi-dimension seismic attribute fusion method and device. The method comprises the steps that the seismic attribute information of a plurality of edge layers of geological explanation layer position data is extracted along an edge position; the seismic attribute information of each edge layer is divided into a preset number of zone block point sets; through an algorithm, the seismic attribute information of one edge layer is selected for representing the geological target features of the seismic attribute information common zone block point sets; and the seismic attribute plane information point sets of the seismic attribute information of all the selected edge layers are integrated into a seismic attribute plane information point set, and infused edge layer seismic attribute information is obtained. The edge layer seismic attribute information obtained by infusion according to the scheme can well reflect different geologic features of a whole geologic body.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration seismic attribute data fusion, in particular to a multi-dimensional seismic attribute fusion method and device. Background technique [0002] Over the past three decades, exploration geophysicists have extracted hundreds of seismic attributes (such as amplitude-like, frequency-like, phase-like, waveform-like, structure-like, prestack-like attributes, and spectral decomposition properties, etc.), and try to qualitatively or quantitatively describe subsurface geological bodies through seismic attributes. How to quickly and effectively extract valuable data from many seismic attributes for geological interpretation has always been a concern of exploration geophysicists. Conventional single seismic attribute data display technology is a method of mapping seismic attribute data into a color image through a certain transformation, and using the difference in visual effect of the color i...
