Study on the Wettability and Spontaneous Imbibition Characteristics of Lacustrine Shale
Geofluids, Volume 2022, Issue 1, 2022., 2022 Wettability plays a significant role in the exploration and development of shale oil. The wettability affects the oil enrichment and restricts the selection of fracturing fluids. Shale is composed of complex minerals and organic matter. The pores composed of inorganic minerals have water wettability, while the pores composed of organic matter show the ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 The Chang 7 member in Ordos Basin is an important shale oil exploration layer, with new shale‐oil discoveries in recent years. The Chang 73 submember is rich in organic shale, which is the main source rock of shale oil in the Yanchang Formation. In order to clarify the lamina structure, composition, types, and distribution characteristics in Chang 73 ...
