Beijing Petroleum Machinery Factory (BPMF) under the CNPC (China National Petroleum Corporation) signed an agreement with an US company on Thursday to provide top-drive oil-drilling equipment which China independently developed and which represents the most advanced level of oil-drilling technology and electromechanical equipment for oil industry. This is China's first export of major oil-drilling equipment to the US.

Top-drive oil-drilling equipment is one of the front technologies in oil-drilling engineering, said Ding Shubai, vice president of the Petrochemical Engineering Research Institute. By far only a few companies are able to produce top-drive oil-drilling equipment. The BPMF top-drive oil-drilling equipment is the first export of China-made top drive which is of independent intellectual property rights. It indicates that China's independently developed oil-drilling equipment has had the ability and level to compete internationally. Direct entry into the high-end market of international oil-drilling equipment is a good beginning for the moving of China's oil equipment toward the world.

David Russell, president of the US company, said that after conducting survey and analysis the BPMF's top drive has proved technologically advanced, qualitatively reliable and the best among all the companies. We are willing to establish long-term cooperation with the BPMF in oil-drilling equipment.

Experts in the industry believe the BPMF' top drive adopts the AC frequency conversion drive technology which represents the direction of world top drive development. It has the excellent performance of speed control and torque control automatic conversion. In particular the topper computer supervising and control system can show the operating condition of the mechanical, electrical and hydraulic systems in real time visual. It has supervising and control and mutual-locking function for the electrical control system as well as self-diagnosis and protection function, which can effectively prevent failures resulting from operation errors. The integration control technology of the mechanical, electrical and hydraulic information for the system as a whole has reached a very high level of automation. It can meet the requirements on rotate speed and torque under various working conditions.

As learned the BPMF's top drive has been used in drilling at the Horgos 001 well in Xinjiang, Gaoquan 1# well and Pakistan's SPA-2 well. Its good price/performance ratio, stable and reliable operation and complete maintenance service are highly appraised by clients.
