Abstract: Research and development of China’s fracturing equipment is committed to the engineering demands and based on the national science and technology major projects and integration of “industry, universities, research and application”. The enterprise is taken as the innovation backbone while the R&D team makes collaboration for innovation. The project management model is adopted to establish the target-oriented examination mechanism and make transformation of achievements on the basis of in-depth integration. As a result, the research efforts led to the fracturing pump technology with high reliability and long service life, the high-efficiency sand-mixing technology with a large displacement capacity, the super-high pressure manifold technology, and the high powered electric motor and frequency converting technology. Innovation also led to manufacture of the 5000-type electrically-powered fracturing assemblage, construction of the production line for electrically-powered fracturing units and the experiment platform, and establishment of the new service model. The systematic super-high powered electric fracturing units were put into large-scale application in the national major oil and gas engineering projects in Peiling, Weirong and Wulong, reducing the comprehensive cost by 30 percent. With the advantages of high power, high efficiency and low noise, the units ensured high-efficiency and cost-effective development of unconventional oil and gas in China.
