Since the 1990s, China's marine economy has developed rapidly at a double-digit annual growth rate. The scope of activities has expanded in many directions, and the economic aggregate has increased rapidly. The growth rate is faster than the national economic growth and the growth of the coastal developed areas that have been in the leading position. The development of the marine industry is faster than the development of the industry as a whole. In 2006, the added value of the marine industry was 828.6 billion yuan, equivalent to 4% of the national GDP. In 2011, the total value of marine production reached 4.56 trillion yuan, an increase of about 4 times compared with 0.93 trillion yuan in 2001. The contribution of the national economy is growing. 
Figure 1 In 2011, China's marine industry added value (100 million yuan) and the proportion of total marine production value and marine high-tech research and development simultaneously developed high-input, high-output, high-risk, high-tech marine high-tech industry The rapid development of marine high technology has led to the expansion of the marine industry cluster. Marine high technology mainly includes marine oil and gas exploration and development technology and its industry, marine monitoring technology and marine instrument manufacturing. With China's marine high technology as the eighth high-tech research and development plan (863 plan), the annual output value of the marine high-tech industry has gradually increased. 
Figure 2: The busy ocean terminal has experts pointed out that the 21st century is the ocean century. How to develop marine resources reasonably and effectively has become the development strategy of all countries and regions in the world, especially for the country with the coastline with the fourth largest country in the world. It is especially important to rationally develop and utilize this valuable wealth. Today, with the increasing energy shortage, the focus of marine development has naturally shifted to the exploration and exploitation of oil. At present, the proven reserves of offshore oil in the world are more than 20 billion tons, and natural gas reserves are 80 trillion cubic meters. More than 100 countries and regions are engaged in offshore oil exploration and development, with an annual investment of 85 billion US dollars. In 2000, offshore oil production was about 1.3 billion tons, accounting for 40% of the world's total oil and gas production, with an output value of about 300 billion US dollars. According to authoritative analysis, marine oil and gas production in the middle of the 21st century will exceed terrestrial oil and gas production. Since the 1970s, the birth of polycrystalline composite sheets has promoted the application of diamonds in the field of drilling tools, and diamond drill bits have been rapidly promoted. Since the 1990s, the total amount of geological and petroleum drill bits in the world has accounted for 70% of the work of diamond drill bits. Table 1 Application of Diamond Drills in Different Rock Formations Advantages Diamond drill bits have absolute advantages over traditional carbide drills: 1. The total cost of drilling is significantly lower than that of carbide drills, generally reduced by 30% to 40%; The ability to drill into the hardest rock formations that traditional drill bits are difficult to drill into; 3. Faster drilling: more visible when drilling hard and dense rock, such as drilling into a particularly hard grade 10 rock, small diameter diamond drilling Up to 1~2m/h, while the steel drill is only 0.2~0.3m/h. 
Figure 3 Diamond composite drill bit According to the “General Plan for High-tech Industrial Chain of Regional Superhard Materials and Products of Henan Provinceâ€, the consumption of petroleum geological drill bit in China reached 3 billion yuan in 2006, and the oil production is approximately proportional to the amount of petroleum geological bit consumed. (Of course, considering the different strata consumption of different drills, the two are not absolutely proportional, and here are approximated). It is predicted that in 2012 and 2013, the output of single wells for oil exploitation will decrease year by year, which means that the number of drill bits consumed by tons of crude oil has increased year by year, and the growth of the oil drill bit market is around 5%. The continuously optimized marine industry structure has improved the international competitiveness of China's marine industry. China's self-built drilling platforms, geophysical vessels, and pipelaying vessels with world-class technological levels have been put into use one after another; in 2010, marine oil and gas production exceeded 50 million tons of oil equivalent for the first time, and truly entered the ranks of large oil and gas producing countries.
