OUR COUNTRY'S FIRST "XUANJI" SYSTEM "INTELLIGENT MANUFACTURING CHAIN" WAS COMPLETED AND PUT INTO PRODUCTION
Xinhua News Agency, Beijing, April 20 (Reporter Dai Xiaohe) The reporter learned from CNOOC that the intelligent production line of my country's first rotary steerable drilling and logging while drilling "Xuanji" system was officially completed and put into production in Foshan, Guangdong on the 20th, marking the beginning of production by The "Xuanji" system independently developed by my country has officially entered a new stage of large-scale industrialization.
Shang Jie, the leader of "Xuanji" system technology and general manager of COSL Oilfield Technology Division, said that rotary steerable drilling and LWD technology are known as the "crown jewel" of oil drilling technology, and CNOOC's "Xuanji" system technology The successful research and development is a revolutionary and subversive technological breakthrough in the field of oil drilling and logging in my country. The system can precisely control the drill bit thousands of meters deep underground to "target" the oil layer, "smell" the oil-smelling drill, and even "remotely drive" the drill tool to stably travel 1,000 meters laterally or obliquely in the thin oil layer of 0.7 meters. The above, at the same time, can realize real-time analysis of stratigraphic data, which is an important magic weapon to greatly reduce the development cost of oil and gas fields and efficiently develop offshore oil and gas resources, representing the highest level of drilling and logging technology development in the world today.
The "Xuanji" system intelligent production line put into production this time is a national major equipment localization project, and is one of the core contents of CNOOC's construction of high-end oil and gas exploration equipment "intelligent manufacturing chain".
Shang Jie said that since the birth of rotary steerable drilling and logging while drilling technology in the 1990s, because it spans more than 20 disciplines, involves more than 1,000 high-end processes, and has as many as millions of lines of control code, it has been adopted by three international companies in the United States. Oilfield service companies have been monopolized for more than 20 years. Facing the high service cost of RMB 1 billion per year, the completely encrypted technology blockade and the monopoly of products that are never sold, COSL successfully developed the "Xuanji" drilling and logging system in 2014 after 7 years of technical research and realized the offshore drilling and logging system. work, making my country the second country in the world to have this technology.
As of March 2022, the "Xuanji" system has been successively applied in the Bohai Sea, South China Sea, East China Sea and major land oil and gas fields, and has been extended to Iraq, Indonesia and other countries.
