北美致密油延续页岩气革命，产量出现大幅度增长，有效带动了水平井钻井技术、压裂技术和配套工具的发展，前景良好。致密油与常规油藏差异较大，但与页岩气在储层特征、产能特点和开发方式方面有很多相似性。通过充分调研国外，尤其是北美地区致密油增产技术进展，对直井特别是水平井致密油钻井技术、分段压裂技术及多井同步压裂等技术进行系统梳理和深入剖析，给出了国外致密油增产技术发展的潜力和优势，为正处于起步阶段的中国致密油开发提供建议。

North America is experiencing a tight oil evolution following the previous shale gas evolution, while petroleum production has increased greatly, which effectively promotes the development of horizontal well drilling technology, fracturing technology and matching tools. Tight oil is quite different from conventional oil reservoirs, but has many similarities with shale gas in reservoir characteristics, production features and development methods. In this paper, through investigation on foreign tight oil technologies, tight oil drilling technology in both vertical and horizontal wells, staged fracturing technology and multi-well fracturing technology were researched and analyzed. The potential and advantages of overseas tight oil well-stimulation method were discussed, and some recommendations for the development of Chinese tight oil in the initial stage were put forward.
