Gas drilling coring technology was improved to address issues like low core recovery and poor core quality. By developing new tools and techniques, researchers achieved an average core rate of 95.46% in wells like Longgang 163 and Puguang 107-1H. This technology can now meet the needs of drilling and geological analysis, with an average core footage of 7.82 meters.
