“璇玑”系统实现新突破！

Core Viewpoint - The "Xuanji" system developed by China National Offshore Oil Corporation (CNOOC) represents a revolutionary breakthrough in oil and gas directional drilling technology, achieving a significant milestone in data transmission and operational efficiency in deep earth exploration [1][2]. Group 1: Technological Advancements - The "Xuanji" system has established a high-speed communication channel for real-time data transmission, surpassing 500G of total data, equivalent to the data from 1,000 wells or a single well of 1 million meters [1][2]. - The system utilizes fluid pressure wave transmission technology, enabling efficient and stable transmission of geological information across various media, including turbulent fluids and atmospheric environments [2]. - The data transmission rate from well to ground has improved from 1bps to 40bps, achieving world-class standards and creating an end-to-end control loop from downhole instruments to decision centers [5]. Group 2: Operational Achievements - The "Xuanji" system successfully completed operations in Uganda, overcoming significant technical challenges such as communication interference and real-time response, ensuring efficient implementation of drilling operations [5][7]. - The system has been applied on a large scale across important oil fields in China and has expanded to countries involved in the Belt and Road Initiative, including Indonesia, Iraq, and Uganda, with a total of 151 operations and 120,000 meters drilled overseas [7]. Group 3: Industry Impact - The "Xuanji" system has been recognized for its global collaborative operational capabilities, providing strong technical support for the exploration and development of complex oil and gas fields [5][7].
