The reporter learned from the Guangzhou Ocean Geological Survey of the Ministry of Land and Resources on the 4th that as one of the national “Eleventh Five-Year Plan†863 plans, a major special project of key technologies and equipment for deepwater oil and gas exploration in the South China Sea has recently passed acceptance by the expert group in Guangzhou. This indicates that China already has a geophysical acquisition technology that can effectively resolve deepwater oil and gas exploration, and possesses deep oil and gas exploration capabilities.
In view of the tendency of international offshore oil exploration to enter the deep sea, during the “Tenth Five-Year Plan†period, the National 863 Plan carried out research on the “Deepwater Oil and Gas Geophysical Exploration Technology†project and achieved success. On this basis, under the National “Eleventh Five-Year Plan†863 Plan, the major projects of “Key technologies and equipment for deepwater oil and gas in the South China Sea†were set up under the “Technology of Collecting, Processing, and Interpreting Integrated Deep-Earth Oil and Gas Geophysics†to initially establish the South China Sea. Characteristics of deep-water large-scale oil and gas basin exploration and comprehensive evaluation technology system.
According to Wen Ning, deputy director of the Guangzhou Marine Geological Survey of the Ministry of Land and Resources, who is responsible for the subject, from 2007, researchers in China started to research methods from the perspective of exploration techniques, and carried out joint research on gravity, magnetic and seismic acquisition and processing technologies, and developed gravity, Magnetic and seismic comprehensive inversion interpretation technology and other key technologies related to deep-water oil and gas geophysical exploration. On this basis, China’s geological survey vessel “Crawling Treasures†has entered the northern part of the South China Sea since March this year to conduct a sea trial of the “Deepwater Oil and Gas Integrated Geophysical Acquisi- tion Technologyâ€, which has completed 217 km of test lines and 18 lines of 15 survey lines. With more than 1,500 kilometers of formal collection workload on the line segment, the collection results have all met the Ministry of Science and Technology's assessment of technical indicators.
Recently, the results of this major project were approved by the expert team led by Dong Weiliang in Guangzhou. The expert group believes that this technology has made a major breakthrough, which indicates that China's accurate positioning of deep-water area acquisition technology and high-precision integrated geophysical measurement technology have been successful. It is an objective understanding of China's deep-water regional basin structure, deep basic geological conditions Etc. Provides highly accurate geophysical information.
According to Dong Weiliang, at present, the world's marine oil and gas exploration reaches a depth of 4,000 meters, and most of the space in the South China Sea with a water depth of 500 to 3,000 meters has a low level of exploration. This technology will enable our country to effectively In the field, we can obtain effective geophysical data for solving deep-water oil and gas problems. The effective depth of geophysical exploration can reach nearly 10,000 meters, providing high-tech support for the exploration and development of national marine oil and gas and other strategic resources.

Bismuth-tin alloy is a metallic alloy composed of bismuth and tin. The alloy is typically made up of 50% bismuth and 50% tin, although the ratio can vary depending on the desired properties. Bismuth-tin alloy is known for its low melting point, which makes it useful in a variety of applications, including soldering, plumbing, and metal casting.
It is also used in the production of low-melting point alloys, such as Wood's metal and Rose's metal. Bismuth-tin alloy is non-toxic and has a low thermal conductivity, which makes it ideal for use in electronic components and heat-sensitive applications.
