Editor's note: Advanced manufacturing is a key to the development of the real economy, and advanced petroleum equipment manufacturing is the foundation to ensure national energy security. General Secretary Xi Jinping made important instructions on promoting a new type of industrialization, pointing out that the requirements of high-quality development should be run through the whole process of new industrialization, and the construction of a manufacturing power should be organically combined with the development of digital economy and industrial informatization, so as to build a strong material and technological foundation for Chinese-style modernization. This newspaper launched a special topic to discuss what key core technical problems my country's petroleum equipment manufacturing industry is still facing, and how the petroleum equipment manufacturing industry can develop to achieve high-level scientific and technological self-reliance, and provide equipment and technical support for my country's oil and gas resource exploration and development and increased storage and production. Stay tuned.

The world's first 12000 Mitte deep automated drilling rig, the world's first 7000-meter CT150 ultra-high-strength continuous tube, the world's first large-scale application of high-precision broadband vibroseis EV56 ...... China's independent research and development of high-end oil equipment successively appeared in the application market.

In recent years, China's petroleum equipment manufacturing industry has made remarkable achievements in scientific and technological innovation, creating a series of high-end fist products. As of the end of 2022, there were more than 2000 enterprises above designated size in my country's petroleum and petrochemical equipment manufacturing industry, with total assets exceeding 650 billion yuan, forming oil drilling and production equipment, pipe equipment, marine engineering equipment, refining and chemical equipment, metal pressure vessels, etc. Industrial clusters and advantageous enterprises. However, the contradictions such as insufficient supply of high-end equipment, dependence on imports of core components, and weak scientific and technological innovation capabilities are still prominent. my country is in a critical period from a major petroleum equipment manufacturing country to a manufacturing power.

the gap in the overall level is getting smaller and smaller,

But some of the key core components are still dependent on imports.

The key core components of high-end equipment are the pain points of China's petroleum equipment manufacturing industry. "my country's high-end petroleum equipment still has a large gap in key components, core materials, and precision manufacturing." Professor Zhang Min, deputy dean of the School of Materials, Xi'an University of Technology, pointed out that my country is currently unable to independently produce important components such as high-pressure and large-flow pumps, high-pressure valves, high-temperature and high-pressure cables, and lacks high-strength special materials such as high-temperature and high-pressure resistance, corrosion resistance, and wear resistance. The development capabilities of these have limited the performance and reliability of my country's high-end petroleum equipment.

Li Xianyi, general manager of Beishi Company of the Academy of Engineering, also pointed out that internationally renowned oil service companies represented by Schlumberger and Halliburton continued to conduct high-end technology and equipment research and development with high-intensity R & D investment, and took the lead in successfully developing a series of high-end petroleum engineering technologies. And equipment, forming a pattern of leading high-end technology and equipment. Only by continuously strengthening the scientific and technological research and development capabilities, improving the level of efficiency and comprehensive competitiveness, can my country's petroleum equipment manufacturing enterprises change from following to running and leading.

As the focus of oil and gas exploration and development is expanding to the "two deep and one non" field, the performance requirements of oil and gas equipment are getting higher and higher. There is still much room for improvement in the application capability of China's high-end petroleum equipment in extreme environments such as deepwater and polar regions. Zhang Min pointed out that my country currently does not have large-scale equipment with complex structures such as ultra-deepwater drilling platforms and polar drilling platforms that are completely independently designed and built, nor does it have the technology to carry out long-term and stable oil and gas exploration and development activities in extreme environments such as deepwater and polar regions. All these restrict the effective use of my country's offshore oil and gas resources.

Intelligent manufacturing of petroleum equipment has just started, and the foundation of digital intelligence is still relatively weak. Wang Weixu, deputy general manager of the National Research Center of Gemstone Machinery Company, said that in recent years, Gemstone Machinery has made breakthroughs in the research and development of automated drilling rigs, desert rapid migration drilling rigs and workover equipment, reservoir reconstruction equipment, marine resource development equipment and new energy equipment. However, it faces challenges in the aspects of intelligent drilling and workover equipment, intelligent fracturing equipment, and design, manufacturing and integration of marine underwater equipment.

The low recognition of domestic brands also restricts the domestic substitution of key components. Dr. Shan Daiwei, manager of Honghua Group's Collaborative Innovation Office, told reporters that although domestic manufacturers actively promote the localization of key core components, some foreign customers are more recognized by western international brands, which is one of the reasons why some key components in high-end equipment still rely on imports. Zhang Min pointed out that at present, my country's high-end petroleum equipment still lacks original technologies and products with independent intellectual property rights and international competitiveness, and has not formed a complete industry standard and specification system. These have affected the market recognition and competition of my country's high-end petroleum equipment. force.

Build high-end equipment,

Technological innovation and mechanism innovation should be two-pronged

To promote a new type of industrialization and accelerate the construction of a manufacturing power, we must firmly grasp the lifeblood of science and technology in our own hands. At present, the complex and changeable international situation has further increased the supply risk of high-end oil and gas equipment, and it is urgent for us to further improve the independent support capability of equipment. At the same time, the state has put forward the goal of "double carbon", and the domestic oil and gas exploration and development is developing in the fields of "deep, old, low, non, and sea". It is also urgent for equipment manufacturing enterprises to concentrate their superior resources to tackle key problems and strive to form a number of original and leading key core technologies.

Zhang Min pointed out that in order to cope with the world-class problems encountered in my country's oil and gas exploration and development, petroleum equipment manufacturing companies need to continuously improve their independent innovation capabilities, strengthen scientific and technological research, and develop high-end equipment that adapts to complex geological conditions and high-risk environments. In particular, we should increase investment in basic theory, key materials, advanced technology, intelligence and other fields, train high-level scientific research personnel, and form a technological system and product system with international competitiveness.

Focusing on the development direction of high-end, intelligent and green, the petroleum equipment manufacturing industry urgently needs to strengthen the deep integration with information technology and new energy technology. Zhang Min pointed out that it is necessary to improve the level of intelligence, digitization, and networking of petroleum equipment, and use technologies such as big data, cloud computing, and the Internet of Things to realize the functions of remote monitoring, fault diagnosis, and optimized scheduling of petroleum equipment, and improve the operation of petroleum equipment. Efficiency and safety. Areas rich in oil and gas resources are often rich in new energy such as wind energy and solar energy, which provides inherent advantages for the use of clean energy for oil and gas equipment. Shan Daiwei pointed out that petroleum equipment manufacturing should strengthen the integration with new energy and CCUS to help the green and low-carbon transformation of the oil and gas industry.

Institutional innovation is an important guarantee and support for technological innovation. It is necessary to improve the system and mechanism of scientific and technological innovation, establish an integrated innovation mechanism of industry, university, research and application, give full play to the resources of equipment manufacturing enterprises, universities, scientific research institutions, industry associations, and other parties, jointly carry out the exploration and application of cutting-edge technologies, and smooth the channels for the transformation of scientific research achievements. Li Xianyi said that it is necessary to make full use of resources such as universities and scientific research institutions, implement intelligence introduction projects, form innovative industry alliances, integrate and share technology and experimental resources, realize the deep integration of industry, university, research and application, and build an efficient collaborative, open and shared R & D platform. Make up for the shortcomings of enterprises in the field of basic research. The key to scientific and technological innovation is talent. Shan Daiwei emphasized that it is necessary to participate in the global talent competition, optimize the industrial layout, and attract global talents. At the same time, it is necessary to strengthen the adjustment of the talent structure, increase the reserve of professional talents in digital information and electronic circuits, and improve the professional structure of talents.

To solve the big but not strong contradiction,

China's oil to build energy equipment R & D innovation highland

As the largest petroleum equipment manufacturer in China, PetroChina has formed a relatively complete petroleum equipment manufacturing industrial system and industrial cluster. Its products involve more than 200 brands in four categories, covering the upper, middle and lower reaches of the oil and gas industry chain. It has the world's largest drilling rig production and manufacturing capacity and the country's largest oil and gas transmission steel pipe production and manufacturing capacity. At the same time, the contradiction between big and not strong is still prominent, especially the innovation ability needs to be improved, the independent core technology is less, the basic research and development is weak, the product competitiveness is not strong, and the key equipment "stuck neck" problem is still obvious.

In order to better support the transformation and development of energy and chemical business, PetroChina has proposed the development direction of accelerating the transformation from service guarantee to self-reliance and self-improvement strategic support for equipment manufacturing enterprises. Centering on the layout of the group's emerging industries, CNPC equipment manufacturing enterprises focus on the responsibility and mission of increasing oil and gas storage and production, refining and chemical transformation and upgrading of equipment support, and the demand for high-end equipment in emerging industries such as new energy and green environmental protection, carry out forward-looking scientific and technological innovation and technological research and development, and promote the development of equipment manufacturing business in the direction of high-end, intelligent and green.
