Title: Junchen Liu: Inventor in Seismic Imaging and Tomography
Introduction
Junchen Liu is an inventor associated with Nanjing, China. His patent work addresses seismic imaging and tomography, with a method designed to incorporate fault-related information into tomography inversion.
Latest Patents
Liu is associated with 1 patent: “Fault Control Beam Tomography Regularization Method and Apparatus, Computer Device, and Storage Medium.” The invention describes acquiring a seismic imaging data volume, extracting a coherence attribute, and resampling that attribute to correspond to a tomography grid. It then uses ray tracing to obtain input ray density and calculates a fault control beam tomography operator from the resampled coherence attribute and ray density. The operator is introduced into a tomography inversion target function as a regularization constraint.
Career Highlights
Liu’s listed company affiliations include China Petroleum & Chemical Corporation and Sinopec Geophysical Research Institute. His patent reflects work on applying fault-aware regularization to seismic tomography inversion.
Collaborations
Hao Zheng and Kai Guo are identified as Liu’s coworkers.
Conclusion
Junchen Liu’s patent focuses on integrating seismic coherence and ray-density information into tomography inversion, contributing a fault-control approach to seismic imaging.
