China has successfully developed a 9000-meter AC frequency conversion ultra-deep well drilling rig

Invested by Xinjiang Petroleum Bureau, China's first 9000-meter AC frequency conversion ultra-deep well drilling rig developed by Shaanxi Baoji Petroleum Machinery Co., Ltd., passed the expert review and acceptance on December 9, making China a comprehensive country after the United States, Italy, Norway and other countries. One of the few countries that have mastered this technology.

The 9000-meter AC frequency conversion ultra-deep well drilling rig adopts advanced all-digital AC frequency conversion control technology to realize intelligent control. The overall layout of the modular design is reasonable and coordinated, and it is resistant to cold, high temperature, leakage, corrosion, explosion and sand. It has the characteristics of high reliability and strong adaptability. Its structure and technical performance have reached the international advanced level, and it can complete land and offshore oil and gas drilling operations with a depth of 9000 meters.

The 9000-meter ultra-deep drilling rig has won 5 national patents, and it is an independent innovation product with the most patents in domestic drilling rig development.
