摘要

随着技术的进步和环保要求的日益提高，页岩气压裂施工采用传统柴油机驱动压裂泵车组施工噪声大、能耗高和占地面积广等不足逐步显现出来，电动压裂设备因其功率和排量大、噪声和能耗低、施工占地少等优势逐步得到规模应用。在系统总结分析国内外电动压裂技术的发展应用历程及特点的基础上，重点介绍了中国石化电动压裂技术的应用规模、时效和成本，剖析了存在的不足，提出了全面升级电动压裂系统、强化施工过程管理、大规模推广应用全电动压裂技术等建议，以期推动我国电动压裂技术发展和应用，为我国深层和常压页岩气开发提供经济高效的技术手段。

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.
