On Apr 22nd, 2011, the technical outcome appraisal conference for Sichuan Honghua’s Research and Application of AC Variable Frequency Direct Driven Top Drive and Its Key Technologies was held in Guanghuan, organized by Sichuan Science and Technology Bureau. The appraisal committee comprised of prominent experts and professors in the realm inspected the manufacturing site, listened to the report by the project team, reviewed related materials, and performed provisional Q&A, discussion, and evaluations; they came to a consensus that “Sichuan Honghua’s direct driven top drive firstly adopts the technical design concept of electromechanical integration, and the integrated performance outweighs the international standards, hence acquiring the authentication”. Zhao Guozhen, Ma Jiaji, Meng yingfeng, Xu Mingheng and other 7 experts and professors were among the committee; also experts from CNPC Chuanqing, GWDC, Zhongyuan Sinopec, and Shengli participated the authentication. Officials from Sichuan Science and Technology Bureau, and Economy and Information Committee anchored the conference. All senior executives from Honghua , including Zhang Mi, Zhao Ping, Ren Jie, were presented.

Direct driven top drive is contemporarily the most important product of standard sets among the oilfield equipment. It replaces the custom pieces, and now widely adopted in oil & gas exploration and production. Honghua’s direct driven top drive integrates mechanic, electric, and hydraulic design, and armed with AC variable frequency motor with a high torque that suits severe environment. It adopts a rack and pinion locking mechanism, with the guide rail equipped with a single pin locking mechanism; therefore the top drive is hardly malfunctioned, highly reliable, convenient for maintenance, strong for overload, widely adaptable, and so on. The main parameters are in accordance with the state standards and the API technical criteria. 14 items were applied for the national patents, among which 5 were invention ones. By far all the patents have gone public, and the ones of practical value have received official endorsement. Recently two Honghua top drives were successfully in commission in Novy Urengoy, Russia, accomplishing directional and horizontal wells up to 13, accumulating footage 45000m, and enduring the test of -30. Further, more models of direct driven top drives were under processing trial. The technical breakthrough and tapping into international markets of Honghua’s direct driven top drive will cast positive effect on China’s status in oilfield equipment industry, and will enhance the competitiveness of China’s top drive products in upscale market.
