[ Focus on Chemical Machinery and Equipment Network ] Oil and gas resources are widely used in various fields as the "* energy" in the world energy structure.
They are not only the "blood" and economic lifeline of modern industry, but also affect energy security and national stability, as well as the world.
One of the focal points of political and economic competition among major powers.

Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment

With the depletion of land-based conventional oil and gas resources, the deep sea, an area with oil and gas exploration potential, has gradually gained attention.
Especially since 2010, deep-water oil and gas exploration has made a series of major breakthroughs, and deep-sea oil and gas has become an important energy replacement field.

According to statistics, offshore oil resources account for about 34% of total oil, of which about 60% are distributed in shallow water areas of the continental shelf, and the remaining 40% are distributed in deep water and ultra-deep water areas.
Therefore, if you master the deep-water offshore oil resource exploration technology, it will bring rich returns to mankind.

China's seas are rich in oil and gas resources.
The oil and gas resources exceed 85 billion tons of oil equivalent.
It is a large oil and gas region in East Asia and one of the largest oil and gas regions in the world.

Among the four sea areas of China's Bohai Sea, Yellow Sea, East China Sea and South China Sea, the South China Sea is rich in oil and gas resources, accounting for more than 75% of the oil and gas geological resources in China's seas.
Next is the Bohai Sea, which accounts for about 14% of oil and gas geological resources.
According to estimates, China's deepwater oil and gas are mainly distributed in the southern South China Sea, and its resources account for nearly half of the total oil and gas resources in the South China Sea.

In the past 10 years, deepwater oil and gas exploration and development engineering technology and equipment manufacturing capabilities have been greatly improved, and there are currently about 400 deepwater oil and gas production equipment of various types in service.

These deep-water oil and gas development equipment mainly include platforms or other floating equipment for deep-water oil and gas drilling or production processing, such as: compliance tower platform (CT)? semi-submersible production platform (SEMIFPS)? tension leg platform (TLP)? deep draft Single-column platform (Spar platform), floating production and storage export device (FPSO), floating liquefied natural gas production and storage export device (FLNG), floating drilling production and storage device (FDPSO), etc.

It is worth mentioning that in 2017, the “Marine Geology No.
8” three-dimensional seismic survey ship, the “Marine Geology No.
9” geophysical and geological comprehensive survey ship, and the “Marine Geology No.
10” were independently designed and built by the Guangzhou Marine Geological Survey of China Geological Survey.
The “No.
” comprehensive geological survey ship has been listed one after another, and together with the existing “Marine Geology No.
6” and “Marine Geology No.
4” survey ships, it constitutes a marine geological survey equipment and technical detection system covering the whole sea area of shallow water, deep water and ultra-deep water.
, Deepwater oil and gas exploration capabilities have been greatly developed.

　　After years of hard exploration, China has initially formed an exploration geological theory and development technology system for large and medium-sized offshore oil and gas fields, has mastered a complete set of technology for the development of oil and gas fields at a depth of 300 m, and has basically realized independent development of oil and gas fields under conditions of a water depth of 1500 m.

　　In 2017, the "Blue Whale No.
1" and "Blue Whale No.
2" ultra-deep water semi-submersible drilling platforms successively entered the list, marking that China's deepwater drilling equipment is at the forefront of the world, and deepwater oil and gas exploration and development capabilities have reached a new level.

　　Although onshore oil and gas exploration methods and technologies can be used on the sea, many methods and technologies are restricted due to the adverse ocean geography and sea environment.

　　For example, the ground geological survey method can be used on land, but it is difficult to deploy it on a large scale at sea; gravity exploration, magnetic exploration, and electrical exploration must be transferred to the survey ship when it comes to sea, and the measurement results are susceptible to the influence of the sea environment; deep water drilling It is necessary to face external environmental issues such as seabed low temperature and high pressure, narrow pressure window, and high shallow geological risk.
Therefore, higher requirements are put forward on the combination of exploration and development related technologies and materials.

　　In addition, core technologies such as deep-water high-precision and complex sea-state seismic acquisition technology and equipment, deep-water data processing and interpretation technology, deep-water few-well/non-well reservoirs, and oil and gas prediction technologies still need to be tackled.

　　With the application of new technologies, new equipment and new materials for oil and gas exploration and development, deepwater oil and gas exploration will inevitably move towards visualization, digitization, and intelligence in the future.

　　Artificial intelligence and augmented reality technology will bring innovations in data acquisition, processing, geological interpretation, and oil and gas identification in the process of oil and gas exploration and development.
Blockchain technology, also known as distributed accounting technology, can use this technology to track, confirm and execute every transaction link from oil and gas wells to consumer terminals, greatly optimizing trade processes and improving the operating efficiency of oil and gas companies.
Intelligent robot technology and intelligent materials can realize drilling, oil and gas production with less human, unmanned, and remote control, which greatly improves drilling efficiency, quality and safety.
