As a comprehensive research university, Sichuan University has listed “Social Service Engineering” as a key project in the “Sichuan University (Science and Technology) Technology Leap-forward Action Plan”, and established “Based on Sichuan, Serving the West, Focusing on the Layout , the radiation of the country" of the industry-university-research cooperation strategy.

In June 2012, Dai Bills, founded in 1888, sent a technical team to Chengdu. In order to witness the development of superhard composite materials led by He Duwei of the Institute of Atomic and Molecular Physics of Sichuan University, this multinational company, which was born in Johannesburg, South Africa, which dominates nearly 40% of the world's diamond mining and trade, pays the “cost” of 10 I pay $5,000 a day, and there are extremely harsh conditions!

According to He Duanwei's budget, this technology, which grows in Chengdu and is still "young" in China, will form an industrial chain with an annual output value of more than 10 billion yuan in the next 10 years.

High-performance composite drill teeth currently rely mainly on imports

He Duanwei, who attracted Dai Biers to "take the classics", is 45 years old this year. In 1995, he graduated from Sichuan University with a master's degree. In 1998, he obtained a doctorate from the Institute of Physics of the Chinese Academy of Sciences. In the following years, he traveled around the world to engage in scientific research. In 2006, He Duanwei introduced talents as a professor at Sichuan University and served as a professor at the Institute of Atomic and Molecular Physics. He continued to work on the development of superhard composite materials that he had not let go for years.

What is the "superhard composite material" that He Duanwei cares about? Simply put, it is the material for the production of drill bits for underground oil. At present, China's high-performance composite drill teeth mainly rely on imports. “The drilled teeth of cemented carbide are cheap, but the detection ability is only tens to hundreds of meters.” However, the polycrystalline diamond (pdc) composite drill teeth, which He Duwei called “industrial teeth”, can penetrate deep into the detection capability. 3000 meters underground! According to him, at present, the drilling of this material requires 2,000 yuan for each import, and 40 to 50 identical drill teeth can form a complete drill bit for underground excavation work.

Building a joint R&D center to drive the rapid development of Rong enterprises

According to He Duanwei, there are about 30 oil and bit drill factories in Chengdu and surrounding areas. The demand for pdc drilling teeth exceeds 1 billion per year, and the world has more than 20 billion. In response to the urgent needs of the domestic and international markets, in the past five years, the High Voltage Science and Technology Laboratory of the Institute of Atomic and Molecular Physics of Sichuan University has invested nearly 20 million yuan to establish a high-performance pdc composite drill for oil and gas drilling that has reached the international advanced level. R&D platform and performance testing platform.

In 2010, He Duanwei's laboratory and Chengdu Bituo Superhard Materials Co., Ltd. established a joint R&D center to provide high-standard technical support. “At present, the company's annual output value has reached 10 million yuan.” Duanwei said. According to his estimation, the research and development of this technology can drive the rapid development of oil and gas drill enterprises in Chengdu and surrounding areas, significantly improve the core competitiveness of oil and gas drilling, and form an industrial chain with an annual output value of more than 10 billion yuan in the next 10 years.

At present, domestic listed companies and Fortune 500 companies have cooperated with He Duanwei to carry out batch trial production of pdc drill teeth, which have reached or exceeded the key indicators such as wear resistance, impact resistance and thermal stability. The international high-end products of the same kind, and in the Chuandong, Qinghai and other regions have carried out oil and gas deep well drilling trials, and achieved good results.

Testing students to be hired at high salaries through multinational companies

In 2008, He Duanwei's research technology was paid attention to by Schlumberger. It is understood that this large multinational enterprise group is one of the world's top 500 companies, with a history of 100 years of development.

Interestingly, from 2004 to 2006, He Duanwei also worked as a researcher in the R&D department of the company, mainly engaged in the development of pdc composite drills for drilling. Later, at the invitation of his alma mater, he chose to return to China. "We have the technical strength, talents and research environment, of course, we can also study superhard composite materials comparable to the international level." He Duanwei said that the raw materials of pdc composite drill teeth are diamonds and binders, but the success or failure It all depends on the core technology.

Schlumberger company came to find him in the same year, which proved his success after returning to China. In the end, the pdc composite drill tooth developed by his laboratory passed the test of the company. A master's degree student he directed was also employed by the company with an annual salary of $95,000. In the past five years, he has undertaken more than 20 projects of various types, with a total funding of nearly 20 million yuan, and 10 domestic and foreign patents. The annual output value of super-hard composite materials developed in cooperation with domestic and foreign enterprises has exceeded 100 million yuan.
