China has quickened its pace in constructing a clean, low-carbon, safe and efficient energy system. According to the report given to the 20th CPC National Congress, China will advance the energy revolution. Greater efforts will be made to explore and develop petroleum and natural gas, discover more untapped reserves, and increase production. Exploiting traditional energies China is the largest energy consumer in the world, and its oil and gas supply is highly dependent on foreign countries. It is no surprise, therefore, that Sun Jinsheng, an academician at the Chinese Academy of Engineering and the chief engineer at the CNPC Engineering Technology R&D Company Limited (CPET), stressed the urgency to deepen the oil and gas exploration. For nearly a decade, China has made remarkable achievements in petroleum engineering. Many pieces of equipment are self-developed, such as the world-leading 7000 meter deep drilling rig and continuous pipe threading equipment. Some tools, like rotary steerable tools and long-distance expansion tools, are also no longer dependent on imports. Oil and gas exploration has been expanded from the shallow layer to deep and extra-deep layer to date, aiming to tap into more underground resources, such as hot dry rock and hydrate. Against this background, the exploitation of oil and gas is faced with a more demanding geological environment, which requires high-performance equipment, and high-temperature and high-pressure resistance tools, said Sun. To have a safe and efficient exploration of oil and gas, in October 2022, CPET, China University of Petroleum, and Southern University of Science and Technology were jointly involved in a project, which focused on tackling major basic scientific obstacles in developing ultra-deep and extra-deep oil and gas. This project has managed to master drilling fluids technology, which can resist ultra-high temperatures, and break through the bottlenecks in drilling and production flow co |
