CCTV News: "You can go up to nine days to catch the moon, and go down to the five oceans to catch turtles." In recent years, my country's marine oil industry has made continuous breakthroughs, and oil and gas exploration and development have achieved a historic leap from a water depth of 300 meters to 1,500 meters. The improvement of marine oil and gas exploration and development capabilities is inseparable from a number of "deep-sea weapons" created in drilling technology, large-scale equipment, engineering construction, etc. They are like keys to open the undersea gate, unlocking deep-sea oil and gas treasures.

To develop marine oil and gas, you must first know where the oil reservoir is. This requires "CT" of the deep-sea strata and accurately draw the "treasure map" of seabed oil and gas, which requires the use of specially developed marine seismic exploration and collection equipment. "Sea Economy" system: "CT" machine for deep-sea strata

The "Sea Economy" system is a complete set of marine seismic exploration collection equipment independently developed by my country. It consists of a variety of equipment such as earthquake source control, streamer collection, integrated navigation, and positioning and control systems. Carrying on deep-water geophysical exploration ships such as "Ocean Oil 720", it can penetrate nearly 10,000 meters below sea level. Since its inauguration, the "Sea Economic" system has successfully completed three-dimensional seismic exploration of 5 construction areas with a total of 6,552 square kilometers in five construction areas in the waters of China.

The China National Offshore Oil Corporation technical team innovatively introduced AI technology, allowing the "Sea Economic" system to quickly identify "interference noise" in the collected data, improve the processing efficiency by more than three times, increase the signal-to-noise ratio of earthquake data by 25%, and significantly improve the imaging clarity, which refreshes the deep-sea deep data processing records in one fell swoop.

The oil and gas reservoirs on the seabed were discovered, and how to remove these treasures is not a simple matter. To open the channel from the seabed to the reservoir, not only does it require matching corresponding platforms, drilling rigs, drill bits and other professional equipment, but also professional technology.

The deep-water semi-submersible drilling platform "Ocean Oil 982", has a maximum drilling depth of 9144 meters, and can carry out oil and natural gas exploration and development operations in a water depth of 1,800 meters.

In the second phase of my country's first deep-water high-pressure natural gas development project, "Deep Sea No. 1", it has overcome four world-class industry problems: deep water, deep layer, high temperature and high pressure. The drilling and completion of 12 underwater gas wells was completed, with an average well depth of more than 5,000 meters and a total well depth of more than 60,000 meters, close to the height of 7 Mount Everest. Explore and establish a deep-water intelligent drilling and completion technology system, including four key technologies, including deep-water high-pressure well safety control technology and deep-water deep-drilling efficiency improvement technology.

Deepwater Excellent Intelligent Drilling and Completion Technology Leads my country's deepwater oil and gas resource development to more efficiently, while also helping to continuously upgrade digital and intelligent safety control technology. China National Offshore Oil Corporation's "Sky Eye Project" deeply integrates advanced machine vision technology and drilling and completion business, and creates 10 featured video recognition scenarios in China.

Deep water drilling completion operations are characterized by high risks, high costs and high technology. Since the 14th Five-Year Plan, domestic drilling and completion technology has made continuous breakthroughs, and the average annual drilling number of offshore has increased by more than 60% compared with the 13th Five-Year Plan. In 2024, the total number of offshore drilling in my country exceeded 1,000 for the first time, and more than 10 technologies represented by deep-water smart drilling and completion technology have made new breakthroughs. Oil and gas development my country's marine engineering super equipment continues to be newly launched

Deep-sea oil and gas development engineering equipment is a key bottleneck. In recent years, my country has vigorously strengthened the original and leading scientific and technological research of key marine equipment, and marine engineering super equipment has been put into use one after another, promoting the exploration and development of marine oil and gas resources to continuously move towards deep water and ultra-deep water.

The conduit rack platform is the most widely used marine oil and gas equipment in the world. With the completion of major equipment such as "Sea Foundation One" and "Sea Foundation Two", my country's 300-meter-level deep water conduit rack platform design, construction and installation technology has reached the world's first-class level.

In terms of deep water equipment construction over 300 meters, my country has successively built the world's first 100,000-ton ultra-deep water semi-submersible oil storage platform "Deep Sea No. 1" energy station, Asia's first cylindrical floating production and oil storage device "Sea Anemone One" and other floating super oil and gas production equipment. It has independently developed a number of deep water construction tools such as 2,000-meter ultra-deep water pile driving hammers, becoming the third country in the world to have the ability to independently develop ultra-deep water oil and gas resources after the United States and Norway. In 2024, the increase in offshore crude oil production accounts for 79% of my country's total crude oil increase

With the continuous breakthrough of major equipment technologies, the pace of exploration and development of deep-sea oil and gas resources in my country has accelerated significantly. In 2024, my country's offshore crude oil production increased by 79% of the country's total crude oil increase. The first large deep-water deep-water oil field of 100 million tons was discovered in the Pearl River Estuary Basin. A number of deep-water oil and gas fields, including the first deep-water high-pressure gas field in China, "Deep-Sea No. 1" Phase II, and the first deep-water oil field secondary development project Liuhua 11-1/4-1, will be built, further promoting deep-sea oil and gas to become an important growth pole for domestic marine energy.
