Abstract:
As technology develops and the requirements for environmental protection rise, the disadvantages of traditional diesel-powered fracturing pumping units manifested themselves and they include loud construction noise, high energy consumption, and large space requirements for operations. As a result, electric fracturing equipment has gradually been adopted on a large scale owing to its advantages of high power, high pumping rate, low noise and energy consumption, and small space requirements for operations. The characteristics of electric fracturing technologies and their development and application history in China and abroad were studied and enumerated. The application scale, timeliness, and cost of Sinopec’s electric fracturing technologies were highlighted, and the shortages were analyzed. Multiple suggestions were proposed, including comprehensively upgrading the electric fracturing system, improving treatment process management, and conducting large-scale promotion and application of all-electric fracturing technologies. This research is expected to promote the development and application of fracturing technologies and provide economic technical means for the development of deep and normal-pressure shale gas in China.
