Sifangda: A new chapter in the wind and wave breaking spectrum

Polycrystalline diamond composite sheets were first used in oilfield mining and coalfield drilling. With the continuous improvement of the performance of the composite sheet and the design level of the drill bit, the range of the drill bit that can be adapted to the drill bit is wider and wider, and the application of the polycrystalline diamond composite drill bit is more and more wide, and is no longer limited to ordinary geological, oilfield exploration, etc. Traditional fields, and widely used in new fields such as natural gas, shale gas, and marine drilling, strongly promote the development of industrial technology.

After nearly five years of efforts, China's oil companies took the lead in obtaining breakthroughs in shale gas exploration in the Sichuan Basin, and explored the first 100 billion cubic meters of shale gas field. The exploration and development technology was basically localized and began to enter the initial stage of large-scale development. China's shale gas resources are buried deeper than the US shale gas resources, and the terrain is more complicated. In addition, the number of wells at home and abroad is increasing year by year, and the difficulty of drilling is gradually increasing. Although a large part of the deep exploration well accounts for 20% of the well depth of the whole well, it consumes 80% of the drilling cost of drilling the whole well. At the same time, with the development of oil exploration industry and offshore drilling platform technology, the market demand for drilling polycrystalline diamond composite sheets is greater, but in the face of diverse complex formations, the difficulty of drilling is improved, and the performance of composite sheets is higher. Requirements, therefore, the development of high-end polycrystalline diamond compacts for complex formations is a key factor in reducing the cost of drilling in the entire well.

Domestic drill manufacturers still focus on the middle and low-end teeth for drilling. The characteristics of China's oil/natural gas drill bit polycrystalline diamond composite sheet industry are “more than perfect”, which is mainly reflected in the low-end market, which is difficult to break through. The performance of composite film barriers, the domestic and international high-end composite film market is still occupied by foreign bit manufacturers. For example, polycrystalline diamond composite sheets suitable for drilling in hard formations, complex formations, deep formations, etc., are mostly occupied by foreign manufacturers. There are three main indicators affecting the quality of polycrystalline diamond compacts: impact resistance, wear resistance, and thermal stability. Develop high-performance polycrystalline diamond compacts to improve their performance indexes, study the influencing factors of residual stress and the drilling process of drill bits, improve drilling speed, reduce drilling costs, and reduce the number of drill bits used. Has important practical significance. Sifangda focuses on composite superhard materials, focuses on high-end polycrystalline diamond composite sheets, increases the research and development of high-end drilling composite sheet products, and constantly breaks high-end technical barriers, and has already gained in the international drill supply system.

With the continuous decline in international oil prices in recent years, the market for polycrystalline diamond compacts for international drilling has also shown a downturn. Sifangda relies on continuous technological advancement and customer development to enable the company to have international advanced technology and good past performance, which creates conditions for the company to break down brand barriers. At the same time, the decline in crude oil prices has forced downstream customers to pay more attention to cost control and enhance their replacement. The power of low-cost suppliers has made the company's cost advantage stand out. Once it enters the international supply chain and the oil price rebounds, the oil film market will usher in rapid development. At the same time, we provide technical guidance on-site services to customers, set up marketing service outlets in the local area, and gradually strengthen strategic cooperation, which can better promote the research and development of other high-end petroleum composite sheets, and greatly promote the product share of domestic and foreign markets.
