The 24th China International Petroleum and Petrochemical Technology and Equipment Exhibition (cippe) is held in Beijing as scheduled. The organizing committee has specially invited academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering and the most influential senior experts in the industry to form a review committee, the committee selecting "New Energy Automated Workover Equipment" as the cippe Innovation Gold Award" from nearly 10,000 exhibits of more than 10,000 exhibitors.

This "New Energy Automated Workover Equipment" was accomplished by SINOPEC OILFIELD EQUIPMENT CORPORATION (Short for “SOFE”), and was assessed by academicians and experts invited by Sinopec Science and Technology Management Department to reach the international advanced level as a whole, with the "DC Micro-grid Energy Balance Control and Full-Electric Drive Technology for the Workover Equipment" being the international leading level.

The total number of oil and gas Wells in China has exceeded 350,000 and it is still on the rise. Efficient and green workover operations are an important means to ensure energy security, and there is a huge demand for high-end and intelligent equipment. Currently, most of the active-service workover equipment in the world are of diesel engine drive, featuring high energy consumption, high emission, high noise, low working efficiency and high working intensity, so there is an urgent demand for automated electric drive equipment. The project of "New Energy Automated Workover Equipment Development and Application" has lasted for ten years, and developed some core technologies such as energy management and control technology for new energy workover operations, workover string automatic handling and whole-process control technology, and development and integration technology for high-efficiency workover equipment & components. Four major categories and seven series electric drive automatic workover equipment have been developed and put into operation in major domestic oil fields and more than 30 countries and regions in oversea market, meeting the requirement for low carbon, environmental protection, safety & cost reduction, efficiency and other essential requirements for workover operation. The promotion and application of these technologies are so remarkable, thus establishing the SOFE workover equipment and technology as the global leader in the market, and promoting the automation and green revolution of workover operations, boosting the continuous stable oil and gas production, high efficiency and green development, and providing solid support for ensuring national energy security.

This technology has been granted 47 patents and 12 software copyrights, leading to the revision of 9 industry standards and publication of 7 theses.

From 2013 to 2024, this project technologies have been applied in 703 sets of equipment in domestic and oversea market. In the recent three years, 120 electric drive energy storage automatic workover rigs have been promoted and applied, achieving zero emissions in the operation process, reducing energy consumption by more than 68%, lowering the labor intensity and reducing 2-3 operators per shift. The safety and reliability are improved, and the promotion prospect is broadening. New energy automated workover equipment is a new milestone in the field of workover equipment development, laying a solid foundation for China to achieve world-leading workover operation technology.
