Abstract

Abstract: During the 14^th Five-Year Plan period, China National Petroleum Corporation (CNPC) kept pace with international logging technology trends and domestic and international oil and gas exploration and development needs. Through comprehensive planning and continuous iteration, CNPC upgraded its portfolio of autonomous equipment for logging and perforation, innovated the “dual-high” petrophysical technology series, developed the “dual-multi” and “dual-integration” logging evaluation technology series, promoted the transformation and upgrading of well logging processing and interpretation towards informatization and intelligence, resulting in nine key technological advancements. During the 15^th Five-Year Plan period, CNPC will align with global energy transition and intelligent development trends. It will continue to focus on the needs of “two deeps, one unconventional, and one mature” oil and gas fields and the exploration and development of wellbore-associated resources. Aiming for world-class development goals, CNPC will persistently improve foundational infrastructure and platform development. It will advance core research in methods and equipment such as asymmetric multi-physics logging, extreme-environment logging tools, integrated “drill & guide” in one trip, and downhole Internet of Things (IoT) for reservoirs. It will also promote the development of key technologies and products including wellbore-adjacent geological imaging, transparent reservoir logging, and artificial intelligence applications, steadily achieving iterative upgrades in logging technology and its intelligent transformation.

Key words: CNPC, well Logging, technological progress, development direction, well logging Equipments, interpretation and evaluation, intelligence
