页岩油资源是重要石油接替资源。夹层型页岩油富集主控因素为储集物性、排烃强度和异常压力，开发关键技术是薄层分布预测和压裂改造工艺。在调研相关文献的基础上，介绍了中国夹层型页岩油油气藏分布、勘探历程及勘探开发现状。从夹层型页岩油基础理论、理论技术、勘探技术、工程技术等方面分析了夹层型页岩油藏勘探开发面临的挑战。展望了中国夹层型页岩油藏勘探开发前景。

Shale oil resources are the important oil replacement resources. The main factors controlling the enrichment of sandwich-type shale oil include reservoir physical property, hydrocarbon expulsion intensity and abnormal pressure, and its key development technologies lie in thin bed distribution prediction and fracturing stimulation process. The distribution situation, exploration history and exploration & development status of sandwich-type shale oil reservoirs in China were introduced after the related literatures were investigated. Then, the challenges to the exploration & development of sandwich-type shale oil reservoirs were analyzed based on the bottlenecks of basic theory, theoretical technology, exploration technology and engineering technology. Finally, the exploration & development prospect of sandwich-type shale oil reservoirs in China was forecasted.
