In order to meet China's development needs for deep oil and gas resources, improve the design and manufacturing level of China's oil drilling equipment and the competitiveness of the drilling team, Baoji Petroleum Machinery Co., Ltd. applied for the research project of 9000 meters drilling rig in September 2001, and the project was subsequently listed as National “Tenth Five-Year Plan†major technical equipment development project. After the project was confirmed, Gem Machinery Company immediately entered the development process, and the product has been successfully developed.
The 9000-meter rig developed by Baoji Petroleum Machinery Co., Ltd. has superior technical performance. The rig adopts the most advanced all-digital AC frequency conversion control technology to realize intelligent control. Its modular design has a reasonable overall layout and is resistant. It has complete design in cold, high temperature resistance, anti-leakage, anti-corrosion, explosion-proof and sand-proof. It has good reliability and adaptability, and can fully meet the needs of land and offshore oil and gas drilling conditions below 9000 meters. A number of independent innovation technologies of the drilling rig have filled the domestic gap, and successively overcome the technical problems of key components such as high-power AC frequency conversion control system, high-power gear transmission single-axis winch, high-power high-pressure drilling pump and large-load derrick base. It is the first 9000-meter drilling rig with independent intellectual property rights developed by China. It has obtained 5 national patents. It is an independent innovation product with the most patents in China.
China's first ultra-deep well oil rig was successfully developed in Shaanxi
China's first 9000-meter AC variable-frequency ultra-deep well drilling rig was successfully developed in Shaanxi Baoji Petroleum Machinery Co., Ltd., and passed the expert acceptance on the 9th. This scientific research broke the monopoly of foreign enterprises on ultra-deep oil rigs.
