The automatic fault interpretation device for the three-dimensional seismic data body can be used for automatically performing fault interpretation on various seismic data; the device has the advantages of high calculation efficiency, objectiveness and accuracy of fault interpretation results, and the like; and fault interpretation accuracy is effectively improved, and seismic interpretation efficiency is improved.

Description

technical field [0001] The invention relates to a seismic fault interpretation device, in particular to a fault automatic interpretation device for a three-dimensional seismic data volume. Background technique [0002] Fault is one of the most common geological phenomena, and its accurate description runs through the entire process of oil and gas field exploration and development research. In the stage of oil and gas exploration, it is of vital significance to study the formation and evolution process of sedimentary basins, divide regional stratigraphic horizons, and analyze favorable structural styles and their formation mechanisms. In the stage of oil and gas development, the fine characterization and description of local small faults is also of great significance for studying the sealing properties of fault block trap boundaries, analyzing oil and gas bearing properties, and finding relatively complete oil and gas bearing fault blocks. [0003] For a long time, the analy...

Problems solved by technology

However, the commonly used fault automatic tracking technology has the disadvantages of small fault fragmentation, low efficiency of fault slice combination, and difficult combination.

In addition, the quantitative calculation of fault attributes is still in the estimation stage, and there is currently no method and software that can quantitatively calculate fault attributes in three-dimensional space

In short, the automatic interpretation of faults is still in the initial stage of exploration, and the automatic calculation of fault attributes is still in the blank stage
