China's first 9000-meter AC variable-frequency ultra-deep well oil drilling rig successfully developed by Baoji Petroleum Machinery Co., Ltd. passed the expert acceptance recently. The advent of the machine marks a major breakthrough in the development of ultra-deep oil rigs in China, breaking the foreign ultra-deep wells. The monopoly of oil rigs.
It is reported that this 9000-meter deep well oil drilling rig adopts the most advanced all-digital AC frequency conversion control technology, realizes intelligent control, has superior technical performance, and is resistant to cold, high temperature, leakage, corrosion, explosion and defense. Sand and other aspects have good reliability and adaptability, can fully meet the needs of 9000 meters deep land and offshore oil and gas drilling conditions, and will improve the oil and gas exploration and development of China's deep ocean oil and gas fields, large displacement wells and other complex oil and gas fields. New level. At the same time, the drilling rig has obtained 5 national patents, and it is an independent innovation product with the most patents in the development of drilling rigs in China.
The development of drilling technology of 9000 meters and above is relatively mature. The United States, Italy, Norway and other countries have produced DC-driven 9000-meter drilling rigs in the 1970s and 1980s, but this technology has been a blank in China. In order to meet China's development needs for deep oil and gas resources and improve the design and manufacture level of oil drilling equipment, the 9000-meter drilling rig research project applied by Baoji Petroleum Machinery Co., Ltd. was listed as the national "10th Five-Year" major technical equipment development project, and was again China National Petroleum Corporation was identified as a major science and technology project in 2005. The successful development of this product has set a new record for the year when China's major oil drilling equipment was established in the same year. As the largest oil drilling equipment R & D and manufacturing base in China, Baoji Petroleum Machinery Co., Ltd. has successively developed a series of oil drilling rigs of various specifications ranging from 1000 meters to 7000 meters, becoming one of the largest rig manufacturers in the world.
Calcium Fluoride Plano-Convex Lenses are ideal for demanding applications that require superior performance from the ultraviolet through the mid-wave infrared spectra.Calcium Fluoride PCX Lenses` low refractive index, high laser damage threshold, and low axial and radial-stress birefringence are highly suitable for use with Excimer lasers or for integration into infrared systems. Additionally, calcium fluoride features low solubility and offers superior hardness to comparable fluoride-based substrates, making these PCX lenses capable of withstanding harsh environments and exposure to the elements.
