Core Viewpoint - The successful completion of the closed-coring technology service for the Liye 106HF well by Shengli Oilfield Engineering Company, achieving an average recovery rate of 97.92%, has received high praise from the client [1]. Group 1: Technical Achievements - The Liye 106HF well has a maximum inclination of 41 degrees and has encountered multiple fractured zones, which posed challenges such as core sticking and blockage during the coring process [1]. - A dedicated project team was established to address these challenges, involving collaboration with the oilfield shale oil project department and the management center for difficult-to-move projects [1]. - The implementation of a "9-meter + 4-meter" dual-tube combination coring technique significantly enhanced coring efficiency, providing technical support for large-scale exploration and development of shale oil in the Shengli oil area [1].
