摘要: 非常规储层渗透率极低,采用常规压裂工艺仅能形成单一的对称裂缝,难以实现非常规油气资源的经济高效开发,必须强制扩大压裂改造体积,提高裂缝的发育程度,提高单井产量。暂堵是提高裂缝复杂程度的有效方法,为此,总结了国内外页岩等非常规储层压裂改造过程中暂堵球、常规类暂堵剂、纤维类暂堵剂以及其他新型合成暂堵剂的研究现状及应用效果,阐述了各类型暂堵剂的适用条件、优缺点等,指出了暂堵剂的发展方向。研究成果对未来非常规储层压裂改造暂堵剂的相关研究具有重要参考价值和指导意义。

Abstract: It is difficult to achieve economic and efficient development of unconventional resources by conventional fracturing technologies which only make single symmetric fractures due to extremely low permeability, so it is necessary to forcibly expand the stimulated reservoir volume by fracturing and make the fracture network more developed to enhance the produce of a single well. Temporary plugging is an effective method to improve fracture complexity. In this paper, a summarization was conducted on the existing studies and application effects of temporary plugging balls, conventional temporary plugging agents, fiber temporary plugging agents and other new synthetic temporary plugging agents used in the fracturing stimulation of unconventional reservoirs such as shale at home and abroad. Moreover, applicable conditions, advantages and disadvantages of the temporary plugging agents were explained, and the future development of temporary plugging agents was also stated clearly. The study results provide a significant reference and guidance for the studies on temporary plugging agents for fracturing stimulation of unconventional reservoirs in the future.

Key words: temporary plugging agent, fracture, unconventional reservoir, fracturing, shale.
