Abstract

The present invention relates to a method and device for automatically picking up and transforming interpretation information in a seismic section bitmap. In the technical scheme, after preprocessing the seismic section bitmap, the two-dimensional geodetic coordinate values ​​and start time values ​​at both ends of the section bitmap are determined, and Automatically calculate and read the actual three-dimensional geodetic coordinates corresponding to the interpretation information points through small intervals, and combine the interpretation results of the same type into one text file, which is convenient for users to import into seismic software for spatial comparison analysis and generate accurate maps, so as to realize the earthquake Rapid digitization of interpretation information in the section bitmap, thereby improving the accuracy and utilization of the interpretation result data in the seismic section bitmap.

Description

technical field [0001] The invention relates to the field of exploration technology, in particular to a method and device for automatically picking up and transforming interpretation information in seismic section bitmaps. Background technique [0002] In the oil and gas industry, oil and gas reservoirs are enriched in specific locations in a certain set of formations underground. The exploration and development of modern oil and natural gas require the use of seismic sections to a large extent to determine the location, depth, and shape of the target formation, and to use it for well location design and reserve calculation. Therefore, it is of great significance to quickly and accurately determine the structural shape and fault spatial characteristics of underground strata through seismic sections. [0003] However, in the process of seismic interpretation, due to data limitations, the utilization rate of the original seismic section pictures is low; especially in overseas...
