Benefits of technology

This patented technology helps solve problems when trying to find out if there are cracks or other defects on reflection surface caused by conventional methods like coherency analysis (CSA) and curvedness analysis (CA). By performing these transformations and combining them together it can help identify any issues related to cracked areas.

Problems solved by technology

In order to accurately estimate how much damage or deformation has occurred during drilling operations on shale rock formations (shales) caused by hydraulics), researchers have developed various techniques called seismoelectricity analysis ("SEA") and geology simulation." These tools help scientists better interpret groundwater movement patterns over time through their ability to generate images from recorded waves without damaging them themselves.

Abstract

The invention relates to a frequency wavenumber domain high-angle fracture extraction method and device, a storage medium and equipment, and the extraction method comprises the following steps: a, measuring a seismic crack to obtain an original seismic data volume, and splitting the original seismic data volume into a plurality of adjacent sub-blocks; b, performing f-k transformation and f-k inverse transformation processing on each sub-block body in the step a; and c, splicing the plurality of sub-blocks processed in the step b to obtain a high-angle fracture extraction result. The extraction method belongs to a high-angle continuous fracture reflection surface extraction method, and solves the problem that a traditional fracture information extraction method for seismic data volumes such as a coherent body and a curvature body cannot extract a high-angle fracture reflection surface.
