摘要致密油包含源储接触和源储紧邻两种典型源储配置关系，且致密油不包含页岩油，这明晰了致密油的定义和分类。从构造、岩石物性和流体性质3 个方面总结了致密油的储层特征。中国致密油资源潜力巨大，是目前中国非常规油气开发领域最为现实的选择。HiWAY 流道水力压裂技术在开发致密油方面极具潜力，已在全球10 个国家的40 多个非常规油气田成功作业，平均增产20%以上，并大幅度节约了用水量和支撑剂使用量，其技术的关键在于通过交替式间歇注入支撑剂和高强度凝胶压裂液在裂缝中产生流道，并利用一种新型的纤维添加物来使流道保持稳定分布。

Abstract：As shown by the actual reservoir development, for ideal tight oil reservoirs, we have two typical kinds of source-reservoir relationship, i.e., the source contacts with the reservoir and the source adjoins the reservoir, and the ideal shale oil is not included in the tight oil . Thus, the definition and the classification of the tight oil are clear. The characteristics of the tight oil reservoirs are summarized, including the aspects of the structure, the petrophysics, and the fluid property. In China, the tight oil has a huge resource potential, which is the most realistic alternative in the unconventional oil and gas development field. HiWAY flow-channel hydraulic fracturing technique has a huge potential in the development of the tight oil, which has been applied in more than forty unconventional oil and gas fields in ten countries successfully, increasing the production by more than 20% while saving plenty of water and proppant. The keys of this new technique are the alternative and intermittent injection of the proppant and the high intensive gelled fracturing fluid, and a patented fabric additive keeping the stable distribution of flow-channel. This technique has not been applied in China so far.

Key words： tight oil reservoir characteristic distribution and potential of resource HiWAY flow-channel hydraulic fracturing technique
