摘要:

总结了中国页岩油气储层改造理论与技术的发展历程及演进路径,为今后的高效勘探开发提供理论指导与技术支撑。通过对比中美页岩储层地质参数特征及差异分析,采用文献追踪方法,系统梳理压裂理念、理论模型及关键技术的演进路径,提出中国页岩油气储层改造技术的整体发展框架。中国通过“高强度改造”弥补储层劣势,压裂液黏度逐步降低至滑溜水主导(占比 > 90%),支撑剂向多级微支撑演进,裂缝监测实现高精度处理与解释,最终形成复杂缝网压裂技术体系及调控闭环系统。揭示了中国特色页岩油气储层改造技术演进规律,提出了地质-工程一体化、少水环保技术和智能化装备等发展方向,对实现页岩油气革命及国家能源战略目标具有重要指导意义。

Abstract:

This study presents a comprehensive review of the development process and evolutionary paths of the theories and technologies for China’s shale oil and gas resevoir stimulation, aiming to provide theoretical guidance and technical support for the efficient exploration and exploitation of shale resources in the future. By comparing the geological parameters and characteristics of shale reservoirs in China and the United States, we systematically organize the evolutionary paths of fracturing concepts, as well as theoretical models and critical technologies for reservoir stimulation, using the citation tracking method. Accordingly, an overall development framework of techniques for China’s shale oil and gas reservoir stimulation is established. China has adopted “intensive stimulation” techniques to overcome the disadvantages of its shale reservoirs. Consequently, the viscosity of fracturing fluids has been gradually reduced, with slickwater predominating presently (accounting for more than 90%). Meanwhile, proppants have evolved toward micro-proppants for supporting multi-scale fractures, and high-precision processing and interpretation have been achieved for fracture monitoring. These advancements have collectively contributed to the development of a fracturing technology system capable of generating complex fracture networks and the establishment of a closed-loop control system. The evolutionary pattern of the shale reservoir simulation technologies with Chinese characteristics is thus revealed, and future development directions, including geological-engineering integration, water-saving and environmentally friendly technologies, and intelligent equipment, are proposed. This study can serve as a valuable guide for advancing the shale oil and gas revolution and achieving national energy strategic goals.
