Oil and gas engineering technology is developing in the direction of "deeper, faster, more economical, greener, safer, and smarter". Enterprises must play the role of innovation as the main body, act as a national strategic scientific and technological force, and strengthen the source of original technology and key technologies for future industries. Equipment research.

The development history of oil and gas industry is a history of scientific and technological innovation, and the progress of engineering technology is a great driving force for the development of oil and gas industry.

The older generation worked hard to build a solid foundation for the development of China's oil and gas industry.

China's modern oil and gas industry has developed slowly, and the gap between engineering technology and equipment and the advanced level of the West has widened. After the founding of New China, the older generation of oil people built the foundation for the development of the oil and gas industry through arduous struggle, established drilling rig equipment and downhole tool manufacturing plants, and realized the localization of some engineering equipment. With the discovery of large oilfields such as Daqing and Shengli, the scale of oil and gas engineering technology and equipment has expanded rapidly. After the reform and opening up, through introduction, technology exchanges, cooperative research and development, and a series of major scientific research projects, China's oil and gas industry has continuously made major engineering and technological breakthroughs, and the gap with foreign advanced levels has been greatly shortened, meeting domestic exploration and development technology needs, and achieving "going out" "Strategic goals.

China's onshore deep oil and gas resources account for 34%, which is an important area for oil and gas storage and production. Over the past few decades, around the deep ultra-deep oil and gas engineering technology, key technology and equipment has made significant progress, forming a full range of drilling rig equipment production capacity, supporting the "drilling power" to "drilling power". China's deep drilling technology was founded in the 1960 s and developed rapidly in the 1980 s. Especially in the past 10 years of independent innovation, the basic theory of drilling and production, technical equipment and so on have been continuously broken through. The first deep well, Songji 6, was drilled in 1966, the first ultra-deep well, Sichuan Nvji, was drilled in 1976, and the first ultra-deep well, Tashen5, was drilled in 2021. Major oil and gas breakthroughs have been made in the exploration and development of ultra-deep oil and gas in Tarim and Sichuan basins, and new areas of "oil and gas resources at a depth of 10,000 meters" are being explored.

my country's offshore oil industry started in the 1950 s. In 1965, my country adopted a self-made "float-type" drilling device to drill three offshore exploration wells in the coastal waters of Yingge. In 1978, China's first bottom-sitting drilling platform "Victory 1" was launched. In 1985, Chengbei oil field was put into operation, becoming the first modern sea oil field in China. In 1996, through foreign cooperation, the first deepwater oilfield, Liuhua 11-1 oilfield, was developed. In May 2012, "Offshore Oil 981" conducted the first independent deepwater oil and gas exploration in the South China Sea. On August 30, 2014, the Lingshui 17-2-1 well test obtained high-yield oil and gas flow, indicating that my country has the technical ability to independently develop offshore high-temperature and high-pressure oil and gas resources. In 2017, "Blue Whale 1", as the core drilling equipment, successfully tested combustible ice in the waters of Shenhu in the northern part of the South China Sea. The self-developed "Deep Sea No. 1" ultra-deep water gas field was completed and put into production in 2021, marking a major breakthrough in the core equipment of deep-water oil and gas exploration and development.

China is rich in unconventional shale oil and gas resources and has great strategic value. In April 2006, Sinopec launched a prospective project for early shale gas resource potential analysis. East China Oil and Gas Branch specializes in the exploration and development of unconventional oil and gas resources. In 2011, the Ministry of Land and Resources listed shale gas as an independent mineral, and the State Energy Administration formulated a shale gas development plan. Construction of Fuling shale gas field started in 2013 and was completed and accepted and put into operation in 2018. Since the "Twelfth Five-Year Plan", my country has achieved unconventional shale oil and gas speed and cost reduction and benefit development through the upgrading and iteration of engineering technology and equipment such as drilling and fracturing, and supported the construction of national shale gas demonstration zones such as Fuling and Weiyuan, as well as Xinjiang Jimsar, Shengli Jiyang shale oil and other national shale oil demonstration zones. my country has become the world's second largest shale gas producer and the only country to achieve commercial scale development of continental shale oil.

Emerging technologies provide new development momentum for the traditional oil and gas industry. The domestic oil and gas industry is comprehensively promoting digital transformation and intelligent development. Intelligent drilling and completion technology is expected to greatly improve drilling and completion efficiency, reservoir drilling rate and oil and gas recovery rate, and accelerate the deep integration and landing application of artificial intelligence technology and oil and gas drilling and completion engineering, which is the focus of the global oil and gas industry in the future.

Technology continues to break through, to create the core competitiveness of oil and gas engineering

Since the beginning of the 21st century, China's conventional oil and gas drilling and completion technology has been further strengthened, the advantages of very characteristic drilling and completion technology have gradually emerged, drilling and completion technology and equipment to achieve independent control, comprehensive protection of continuous exploration breakthroughs, development and efficient production.

First, deep and ultra-deep well drilling and completion technology is advancing by leaps and bounds.

my country's onshore deep and ultra-deep wells are mainly distributed in the Tarim Basin and the Sichuan Basin. The number of deep and ultra-deep wells is showing an obvious upward trend, and new breakthroughs have been made in ultra-deep well drilling and completion technology and equipment. Has developed 12000 Mitte deep well automated drilling rig, 35 MPa fine control pressure drilling device and other core equipment tools. One-button human-computer interaction automatic drilling rig mass production, mud pump, special drill bit and power drilling tool product performance continues to improve, top drive casing, AC frequency conversion motor comprehensive performance is better than similar foreign products, high-power cementing equipment has reached the international leading level. The export of oil and gas engineering equipment manufacturing industry has rapidly developed from mechanical parts to complete sets of equipment with higher technical added value. Onshore oil drilling rigs and supporting equipment have formed a large-scale market in the world's major oil and gas producing areas, and the marketing network has radiated nearly 90% of the world's oil-producing countries.

Through the key technology research of extra-deep drilling and completion, a series of breakthroughs have been made in integrated design, drilling equipment, drilling speed, downhole measurement and control, wellbore strengthening, high-temperature cementing, safety control, completion testing, etc., forming an extra-deep safe and efficient drilling and completion technology system, successfully implementing a number of landmark drilling operations, and realizing a historic leap from deep and ultra-deep wells to extra-deep wells in oil and gas exploration and development, the drilling capacity of deep wells exceeded 9000 meters and marched to a depth of 10,000 meters. Up to now, my country has built a number of ultra-deep and ultra-deep oil and gas fields in the Tarim Basin and Sichuan Basin, such as Shunbei, Fuman, and Yuanba, which are at the forefront of the world's onshore deep oil and gas development.
