- Abstract
Rich shale oil resources are contained in the 7th Member of the Yanchang Formation (Chang 7 Member) in the Ordos Basin. The exploration and development of the Chang 7 Member sandstone interbedded shale oil has made substantial breakthroughs. The exploration and development potential of the shale oil, an important oil and gas replacement for Changqing Oilfield in the future, is huge. But its related geological basic re⁃ search is relatively weak. This paper gives elaborations and thinkings on basic science issues, including: Characteristics of mud shale, the significance of shale oil exploration, the restoration of the formation of paleo-environment, the organic matter enrichment effect of tuff and the catalysis of hydrocarbon generation, etc. It is believed that continuous attention should be paid to related geological basic research, such as pure mud shale-type shale oil, and modern lacustrine semi-deep lake-deep lake facies sedimentation investigations can provide valuable ideas and methods for the study of mud shale formation, paleoenvironment restoration and formation mechanism. Meanwhile, we should pay close attention to the research on the catalysis of tuff on the hydrocarbon generation of source rocks and carry out a series of thermal simulation experiments on the catalysis of enriched elements in the tuff, providing important basic geological parameters for the exploration and development of Chang 7 Member pure mud shale-type shale oil.
