Abstract

The embodiment of the invention provides a seismic attribute processing method and device, computer equipment and a readable storage medium, and the method comprises the steps: carrying out the rotation superposition of five-dimensional seismic data volumes based on different rotation factor combinations, and obtaining a plurality of superposed data volumes; for each superposition data volume, decomposing the single-channel seismic attribute data in the superposition data volume into a plurality of amplitude modulation-frequency modulation attribute signals, and enabling a value superposition value of the plurality of amplitude modulation-frequency modulation attribute signals obtained through decomposition and a value of the single-channel seismic attribute data to meet a preset error value, and enabling all amplitude modulation-frequency modulation attribute signals obtained through decomposition to form an attribute signal set; and filtering noise in the attribute signal set, and fusing amplitude modulation-frequency modulation attribute signals in the attribute signal set. According to the scheme, the accuracy and the reliability of a fusion result can be improved, and an effective, accurate and reliable data basis can be provided for application scenes such as oil and gas reservoir prediction, fluid identification and well location deployment.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas exploration, in particular to a seismic attribute processing method, device, computer equipment and readable storage medium. Background technique [0002] Seismic attribute is any kind of seismic data measurement that can help us enhance the visual effect of the target interval or describe the target structure with numbers. It is the geometric, kinematic, dynamic or statistical characteristics of seismic wave propagation derived from seismic data. The measurement value of seismic wave, including curvature, amplitude, waveform, frequency, velocity, attenuation, dip, azimuth, etc., has long been used as one of the main research contents of seismic special processing and interpretation. With the development of seismic exploration and computer technology, more and more types of seismic attributes are acquired. Nowadays, in actual application and various theoretical researches, there are m...
