【摘要】：致密油可划分为源储互层型、源下储上型、源上储下型和源储一体型4种类型。通过中美致密油形成条件、资源潜力和开发现状对比,提出美国致密油大多为海相,技术可采资源主要分布在前陆盆地的二叠系、白垩系和泥盆系,主要富集在Permian、Western Gulf和Williston 3个盆地,主要储层为碳酸盐岩;中国已发现的致密油均为陆相,技术可采资源主要分布在克拉通盆地和裂谷盆地的三叠系、白垩系和古近系,主要富集在鄂尔多斯、松辽和渤海湾3个盆地,主要储层为砂岩。中国致密油资源潜力大、分布范围广,但地质与地表条件复杂,规模开发需要较长时间理论认识和工程技术准备,应给予适当的政策扶持。预测2030年我国致密油年产量有望达到(1 500~2 500)×10~4t,将成为石油生产的重要补充。
[Abstract]:Dense oil can be divided into four types: source reservoir interlayer type, source bottom storage type, source upper storage type and source storage type.Based on the comparison of the formation conditions, resource potential and development status of dense oil between China and the United States, it is suggested that most of the dense oil in the United States is marine, and the technically recoverable resources are mainly distributed in Permian, Cretaceous and Devonian systems in Foreland basins.The main reservoirs are carbonate rocks, and the dense oil found in China are all continental facies, and the technically recoverable resources are mainly distributed in the Triassic, Cretaceous and Paleogene systems in the craton basin and rift basin.It is mainly concentrated in Ordos, Songliao and Bohai Bay basins, and the main reservoir is sandstone.China has a large potential and wide distribution of dense oil resources, but the geological and surface conditions are complex, and the development of scale requires a long time of theoretical understanding and engineering technical preparation, which should be given appropriate policy support.It is predicted that the annual production of dense oil in China is expected to reach 1 500 ~ 2 500 脳 10 ~ (4) t by 2030, which will be an important supplement to petroleum production.
