Development history of composite superhard materials The generation and development of the composite superhard materials industry benefited from the successful development of synthetic diamonds by General Electric Company (GE) in the 1950s. This period is a preliminary research and development stage with low technical level and small production scale.
Since then, in 1977, GE has developed diamond sintered body (PCD) and cubic boron nitride (PCBN), and made into blades, which has led to the rapid development of diamond superhard materials, the technical level has risen significantly, and the application field has expanded to drilling tools. And cutting tools. At present, the technical process of polycrystalline diamond composite sheets is very mature, which can meet various geological exploration work and greatly improve the working efficiency of oil and gas exploration work.
Compared with the development of foreign super-hard materials industry, China's super-hard materials industry started late, and it was not until 1963 that artificial diamond was successfully developed.
Early synthetic diamonds were mainly used in abrasives. Before and after 2000, China's superhard materials industry ushered in the first industrial development. The traditional sheet-like process was upgraded to a powder process, which caused the cost of diamonds to drop drastically. Since then, China's diamond production has risen rapidly, with annual production accounting for about 80% of the world's total production.
In recent years, due to the rapid progress of the large-scale press of the six-face press in China's diamond industry, the super-hard materials industry has ushered in the second major industrial development, and the diamond production cost has been further reduced. The product quality and process technology are close to the international level. Domestic diamond composite sheets gradually replace imported diamond composite sheets in the fields of cutting knives, coal fields and mining tools. Domestic high-end petroleum composite sheets enter the international market, and the export volume continues to increase.
Market size of composite superhard materials and future development prospects of the industry
With the continuous expansion of downstream application market demand, the downstream demand for composite super-hard materials is showing a rapid growth trend. According to the monitoring data of the Prospective Industry Research Institute, the current output value of domestic superhard materials and products is between 1:3-1:6. With the growing market size of downstream composite superhard materials, the market demand for composite superhard materials With the expansion, the market demand for high-grade diamonds accounts for about 60-70% of the total market.
First, the market capacity and demand for PCD composites for oil/natural gas drill bits are mainly determined by the market demand for downstream oil and gas drill bits, and the demand for oil and gas drill bits is mainly determined by the oil and gas market demand and the mining plan of oil and gas exploration enterprises.
Statistics show that in 2009 China's oil production was 189.49 million tons, while consumption was as high as 384.845 million tons. The oil is highly dependent on foreign countries. The Outline of the Twelfth Five-Year Plan for National Economic and Social Development of the People's Republic of China clearly states that it is necessary to increase oil exploration and development efforts and stabilize domestic oil production.
On the other hand, China's natural gas production and consumption are generally on the rise. The data shows that from 2005 to 2011, China's natural gas production has been showing a rapid growth trend. In 2011, China's natural gas production grew rapidly, with output accounting for 3.1% of global natural gas production, reaching 102.5 billion cubic meters, an increase of 8.12% year-on-year.
As China's oil and gas production continues to grow, the demand for diamond composite sheets for oil and gas also shows strong demand. At present, the global market size of PCD composite sheets for oil and gas is about 11 billion yuan, and the market space in China is about 1.4 billion yuan. The development potential is huge.
According to the "2011 Global Assessment of Global Shale Gas Resources" published by the US Energy Agency (EIA), China is the country with the largest shale gas reserves in the world, with recoverable reserves of about 36.1 trillion cubic meters, much higher than other countries in the world. . Entering the "Twelfth Five-Year Plan", China regards shale gas exploration and development as one of the important development areas of the national energy strategy, and points out in the "Twelfth Five-Year Plan for National Economic and Social Development of the People's Republic of China" In the development and utilization of unconventional oil and gas resources such as gas and shale gas, the goal of “Shale Gas Development Plan (2011-2015)†is to “strive to achieve 600-100 billion cubic meters of production by 2020â€. Therefore, with the deepening of the development and utilization of shale gas, the PCD composite film for oil and gas will surely usher in new development opportunities, and the market scale will be further expanded.
Secondly, the market demand for PCD composite sheets for coalfield/mine tools is mainly affected by the amount of coal mined. Statistics from the National Bureau of Statistics show that from 1990 to 2009, China's coal production and consumption have shown a growing trend, and the basic balance of production and consumption. In 2011, China's total raw coal output reached 3.52 billion tons, an increase of 8.7% year-on-year. Under the continuous driving of coal production, the scale of China's mining diamond composite sheet market continues to expand. The global market for mining composite sheets is nearly 20 billion yuan, and the size of the Chinese market is about 2 billion yuan.
Thirdly, PCD high-grade drawing die blanks are driven by huge demand in industrial production and engineering construction, and the market capacity is considerable. However, due to the high production cost and high price of PCD drawing die blanks, only some of the wire drawing effects are currently available. End users with higher precision requirements use PCD drawing die blanks, and the market capacity needs to be further expanded.
Competitive Analysis of Key Enterprises in Composite Superhard Materials Industry
Throughout the global composite superhard materials market, the high-end market is mainly monopolized by large groups in the United States, Japan and other countries. Representative companies include Element Six, American DI, Sumitomo and Korea Rijin. These enterprises are technologically advanced and mature in the middle and high-end products. Most of them use large-tonnage two-side synthesis equipment to produce synthetic diamonds, and they have good corporate reputation and brand advantages in the international market.
China's composite superhard materials industry has a certain technological gap compared with advanced countries, especially high-end composite superhard materials. There are not many enterprises in the high-end composite super-hard materials industry. The main competitors are Sifangda, Shenzhen Haimingrun, Zhengzhou Xinya, Huanghe Cyclone, Henan Yalong and Zhengzhou Sanmao. These enterprises have the production of high-end diamond composites. The technology and technology of the film, the product quality is excellent, and has a good reputation and stable customers in the domestic and foreign markets. It is a high-quality enterprise in the field of composite superhard materials in China. However, due to many factors such as product quality, it has not yet entered the ranks of mainstream suppliers in the mid-to-high-end composite super-hard materials market. It is necessary to continuously increase capital investment and technology research and development, improve product quality, and compete fully with foreign large-scale manufacturers to compete for higher profit levels. The market for high-end composite superhard materials.
At this stage, the development of China's composite superhard materials industry has two advantages.
First, the industrial chain of China's composite superhard materials industry has formed a certain scale, and has a local advantage in the procurement of raw materials. The upstream synthetic diamond industry is the main raw material for the composite superhard industry and has a huge impact on the industry. China's diamond production has entered a period of rapid growth since the 1990s. In 2001, the annual output was 1.6 billion carats. In 2009, the output reached 5.4 billion carats. It has become the world's largest producer, consumer and exporter of superhard materials. More than 90% of the world's total annual output of synthetic diamonds has reached 11 billion carats in 2011. The rapid development of diamond production has laid a good foundation for the development of the diamond composite sheet industry.
Second, China has relatively low manufacturing costs, so products entering the international market have low-cost advantages and are easier to gain market share. With the continuous improvement of technology research and development and production technology, the cost performance of composite super-hard materials is gradually reflected. Cemented carbide and high-speed steel are gradually replaced by diamonds, and the market demand is expanding. The timing of industrialization and large-scale development of diamond composite sheets in China has matured.
