[ China Instrument Network Instrument Development ] The exploration and development of deep-sea oil and gas resources is an important foreword in the petroleum industry. Compared with continental shelf and onshore exploration drilling operations, the construction risk of deepwater operations is high. The exploration and development of deepwater and ultra-deep water must rely on Advanced technology and strong economic strength.
With the deepening of deepwater oil and gas exploration, high-resolution 3D seismic technology, 4/4D (4C/4D) seismic technology, large displacement horizontal and branch well technology, intelligent completion technology, various deep water platforms and more and more The more intelligent seabed production systems, etc., are increasingly being used in the exploration and development of deepwater oil and gas.
In the "National Medium- and Long-Term Science and Technology Development Plan (2006-2020)", it is mentioned that the development of multi-functional, multi-parameter and long-term marine integrated development technologies should be emphasized to improve the comprehensive technical capabilities of deep-sea operations. Among them, deep sea operation technology is one of the key points in the development of marine technology.
After years of hard work, especially with the support of the national "863" plan, China's deep sea exploration technology and equipment development has made great progress. For example, the 7-kilometer ultraviolet laser Raman spectroscopy developed by scientists at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences is the first UV-Raman Raman spectrometer for deep-sea exploration in the world, which can detect 99% of the world's Shanghai-based molecular spectrum; China's self-developed "Jilong" manned submersible is the world's deepest working manned submersible, which can be used in a vast sea area of ​​99.8% of the world's ocean area. China's international influence in the field of deep sea exploration technology provides a strong technical guarantee for China's deep sea resources exploration.
In order to further improve China's deep-sea exploration technology, on December 7th, Prof. Jianhua Jian from the College of Ocean and Earth Sciences was appointed as the project's national key research and development program. The project of “Deep-water submarine flight node seismograph development and oil and gas exploration application research†started and technology The seminar was held at Tongji University. 45 experts from the project advisory group and members of the project team attended the meeting.
It is reported that the project is aimed at the current ultra-deepwater oil and gas exploration and scientific research needs, and develops a new submarine flight node seismograph with autonomous motion, autonomous navigation and seismic signal acquisition functions, and develops elastic vector wave imaging and interpretation technology for seabed four-component seismic data. The experimental application in the ultra-deep water basin in the northern part of the South China Sea, combined with the drilling data of the South China Sea Ocean, reveals the oil and gas exploration potential of the ultra-deep water basin in the South China Sea, and provides new means, new methods and new technologies for seismic exploration and scientific research of ultra-deep water and oil in China, filling the technology in China.
