AI Technical Summary
Existing technologies are insufficient to accurately characterize the fracture system and the distribution patterns of fractures in reservoirs, and to quantitatively describe the connectivity of fracture systems, thus affecting the effectiveness of oil and gas exploration and development.
Seismic data is preprocessed using a construction-preserving filtering method to extract fracture development information, calculate the probability values of fracture distribution, discretize the fracture system by combining dip and azimuth constraints, count the number of connected fracture samples, and generate a connectivity image.
It enables detailed characterization of fracture systems and quantitative description of connectivity in underground spaces, improving the accuracy of reservoir evaluation, guiding oil and gas exploration and drilling deployment, and reducing development risks.
