China News Service, Xiangtan, June 18th (reporter Fu Jun, correspondent Zou Pinghui) In the field of deep-sea drilling rigs, 50 meters is a road ridge. Which country has more than 50 meters of deep-sea drilling depth of equipment, has the international advanced deep-sea drilling capabilities, can explore more deep seabed mineral resources.
A few days ago, with China’s self-developed submarine 60-meter multi-purpose drilling rig “Manateau†successfully tested in the deep-sea trials in the South China Sea, China’s deep-sea drilling rig technology became one of the world’s best and became the fourth master in the world “with a water depth of more than 3,000 meters. Deep seabed, 60m drilling technology for countries on the seabed. According to the provisions of the UN, international seabed mineral resources follow the rules of who has the ability to explore first, and whoever has the priority for development, and “sea cows†will become a sharp weapon for China to seize the right to exploitation of mineral resources on the high seas.
“I have been engaged in marine geological exploration for decades. I have never seen a submarine rock below 3,000 meters. Today, I have a chance to see it.†Facing the surveillance image of Haifeng, Zhou Yangrui, chief engineer of the COSL Geophysical Exploration Department, was excited. Endlessly.
At 10:11 pm on June 11th, “Manatee†officially drilled the first shot in a certain area of ​​the South China Sea. The multi-functional robot extends out, the chuck rotates, the drill pipe is drilled, and the lower drill tool... Under the remote control of the computer, a series of drilling actions can be accurately performed at the depth of more than 3,000 meters in the sea and 8 tons of manatees. Acceptance experts kept nodding for praise. At 8:10 am the following day, with the last drill rod drilled in the end, the "Haniolo" finally drilled 60 meters under the sea of ​​3,109 meters.
As confirmed by the expert team of the National 863 Plan Project on the sea, the “Hainiu†sea trial led by the Hunan University of Science and Technology, the Institute of Oceanography of the Chinese Academy of Sciences and the Guangzhou Marine Geological Survey participated in the research and development, and the drilling depth of the Chinese deep-sea drilling rig was refreshed.
Looking at the world, in the field of deep-sea drilling rigs, the United States, Germany, and Australia alone mastered the technology, and 50 meters is an insurmountable road. Professor Wan Buyan, chief scientist of the “Technology for the Development and Application of Submarine 60m Multi-purpose Drilling Rig System†and a professor at Hunan University of Science and Technology, introduced the reporter to the China-Singing News. After crossing this road, he and his team mainly conquered two major technical difficulties. First, Through the "rope coring" key technology, under the computer control of the deep-sea drilling rig under the unmanned automation of the seabed, greatly improving the operating efficiency. In addition, as the drilling depth increases, the rig's volume and weight are also more limited. Through lightweight design, the weight of “Haniolo†is only two-thirds of that of the same type of foreign drilling rigs, which is easier to install and control. It is suitable for loading on various types of scientific research vessels and has a wider use prospect.
As the inventor of China's first deep-sea drilling equipment, Wanbu Yan and his team witnessed the development of China's deepwater drilling rig technology. "Before China conducted exploration of ocean resources in 1999, it could be said that it did not have its own deep-sea drilling rig technology. All drilling rig parts, even if it was a steel pipe, had to be imported from abroad." Wan Fuyan recalled that at the time it was due to Western technology. The blockade, China reluctantly rented a drilling rig with a drilling depth of 0.7 meters from Russia at a high price of 80,000 US dollars a day. As a result, after many drills, it unfortunately ended in failure.
It is precisely this experience that has led to drilling research has been deeply determined, "must develop its own deep-sea drilling equipment!" Since 2003 the first deep sea drilling equipment was born in 2006 to create a cobalt-rich knot The shell sampler was used in the deep-sea exploration of the “Neolongâ€, and the drilling depth was increased step by step to 2 meters, 20 meters, and 60 meters, making China’s deep-sea drilling rig drill more than 1,000 exploration holes in major oceans around the world, becoming a global Deep sea rigs are the most used offshore applications. Wan Buyan led his team through continuous innovation and achieved a series of remarkable achievements in the field of deep sea drilling equipment R&D.
“Live a day and it will take one day.†The step-by-step rule that abides by the idea is not intoxicated with existing achievements. According to its introduction, the drilling depth of the world's most advanced subsea drilling rig can be successfully achieved at about 120 meters, and a 200-meter drilling rig is under development. The team will next set its sights on deep-sea drilling rigs that can meet the demand for flammable ice exploration and strive to achieve a drilling depth of 220 to 230 meters. "If we can successfully develop within two or three years, we may win the world number one." He said that he would not wait for me, so we must continue to work harder.
