which is expected to break through a number of technical limits of offshore oil and gas development, and establish a technical system for exploration and development of offshore complex oil and gas resources. Further releasing the resource potential of Yinggehai Basin is of great significance to fully building the trillion-atmosphere area of the South China Sea and increasing the rate of energy self-sufficiency.

Quality is the lifeline of an enterprise and the key to winning the market. Therefore, we strictly control the quality of every link from product design, production, inspection, sales to after-sales service to ensure that every product can meet the needs and expectations of customers.

The petroleum machinery market is developing rapidly, and the investment projects in the domestic petroleum machinery industry are gradually increasing. At present, China's petroleum machinery industry is in the growth period of the industry, China has developed more fully in the low-end market of the industry, but there is still a very large room for progress in the high-end product market.

The largest uninhabited land in the world, with an area larger than four Indias and oil reserves of 100 billion barrels Hello, welcome to the new episode, the world is facing an increasingly serious energy crisis, countries around the world are attaching great importance to domestic resources, but also actively looking for external energy supplements. Antarctica, as a no-man's land, has not been large-scale development because it is too cold, and there is a huge amount of energy resources under the ice, which has a very important role in our study of the earth.

Petroleum machinery and equipment is an important tool in the process of production and development of petroleum enterprises. With the development of science and technology, the types of petroleum machinery and equipment are more and more, and the performance is more and more perfect. In this context, the previous equipment management method is obviously no longer suitable for the current management and maintenance of petroleum machinery and equipment.

Oil is an important driving force. Petroleum instruments are needed to evaluate the function and quality of petroleum and petroleum products from the aspects of oil exploitation, transportation, refining, selling and application.

In the future, we will further strengthen cooperation with Beishi Company, continuously improve shale gas mining efficiency, reduce mining costs, realize green and low-carbon transformation and development, and make positive contributions to promoting the construction of shale gas production capacity of 5 billion cubic meters in Zhejiang Oilfield.

"With a diameter of 2.86 meters, family cars can easily pass by. This is the first time we have produced and processed such a' super-large-diameter' slide valve". On November 22, Ma Xiaocheng, the production and operation center of PetroChina Bohai Equipment Petrochemical Equipment Company, said that the world's largest diameter double-acting slide valve processed and produced by the company has entered the flange plane processing process.

General manager of China Offshore Oil Exploration Department, said that the success of the first offshore shale oil is a major breakthrough in offshore oil and gas exploration, which has realized the independent exploration and development of China's offshore shale oil and gas resources with our own equipment and technology, and opened the prelude to unconventional offshore oil and gas exploration and development, with huge resource potential, which has consolidated the resource base for firmly holding the energy rice bowl in our own hands.
