Chemical equipment has developed greatly in the past ten years. Praise for China's prosperity and strength in the prosperous age. It will be more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. Everyone pays attention to safety and knows how to respond to emergencies. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * On June 2, 2020, reporters learned from China National Offshore Oil Corporation (hereinafter referred to as "CNOOC") that recently, as the last 12-inch submarine pipeline terminated and entered the sea, my country's largest deep-water submarine pipeline laying project - the Lingshui 17-2 gas field submarine pipeline laying started for the first time. The phase operation was successfully completed in the western waters of the South China Sea. This submarine pipeline laying operation is one of the overall development projects of the Lingshui 17-2 gas field. The water depth of the pipe laying operation was 1,542 meters, setting a new record for the depth of my country's submarine pipeline laying and marking a new breakthrough in my country's deepwater oil and gas resource development capabilities. It marks another major breakthrough in my country's deepwater oil and gas resource development capabilities, and is important for ensuring * * Energy security and supporting the strategy of maritime power are of great significance. Since it was put into use, the construction work vessel "Offshore Oil 201" has broken my country's submarine pipeline laying records more than 20 times and has become a key equipment for my country's independent development of deep-sea oil and gas resources. According to reports, submarine pipelines are the "arteries" for offshore oil and gas transportation and are known as the "lifeline" of the offshore oil and gas production system. Submarine pipeline laying construction operations are difficult and require extremely high welding technology and equipment capabilities. At the same time, with the increase of water depth and the influence of factors such as unstable seabed and low rock strength, the technical difficulty of laying submarine pipelines has increased exponentially. The industry believes that submarine pipeline laying is a test for * * One of the important indicators of the overall level of offshore oil and gas resource development capabilities. Previously, the laying technology of submarine pipelines in deep water areas above 1,500 meters has been monopolized by a few international petroleum engineering companies. As my country's first deep-sea oil and gas development project with a water depth of more than 1,500 meters, the Lingshui 17-2 project is not only CNOOC, but also the first time that China's offshore engineering industry has set foot in 1,500-meter deep-sea pipe laying operations. During this operation, CNOOC also carried out technical research on various properties such as the tensile, impact and hardness of deep-water pipelines, and finally figured out the relevant requirements for ultra-high precision, surface quality, anti-corrosion and oxidation resistance of deep-water submarine pipelines, and successfully realized the localization of deep-water submarine pipelines. The Lingshui 17-2 gas field where the submarine pipeline is being laid this time is one of my country's important oil and gas discoveries in recent years. It was drilled by CNOOC in 2014 and has proven geological reserves of over 100 billion cubic meters. The gas field is 150 kilometers away from Hainan Island. Wang Dongjin, chairman of CNOOC, said that the sudden COVID-19 epidemic and the challenge of low oil prices have not affected the company's pace of increasing domestic oil and gas exploration and development. CNOOC is making every effort to promote the construction of a number of major projects and oil and gas development projects such as Lingshui 17-2 and Bozhong 19-6. You Xuegang, deputy general manager of CNOOC Zhanjiang Branch, said that in addition to submarine pipeline laying operations, development projects such as development well operations and production platform construction in the Lingshui 17-2 gas field are also being intensively advanced. The gas field is expected to be put into production in 2021 and will stably supply 3 billion cubic meters of gas to Guangdong, Hong Kong and other places every year, which can meet a quarter of the people's gas demand in the Greater Bay Area.
