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 Long12 block of Longhupao oilfield is located in the western slope area of Qijia‐Gulong Sag, which lay in the central depression of Songliao basin. Recent exploration and development shows that Putaohua oil layer has great potential storage. However, the block is located in the ring concave fault zone, with complex geological background and extensive ...

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 ...

Geofluids, Volume 2021, Issue 1, 2021., 2021 The Qijia Sag, a secondary tectonic unit in the northern Songliao Basin, developed plentiful shale oil resources in the first member of the Cretaceous Qingshankou Formation (K2qn1) as its main target layer. However, the systematic study on the geological and geochemical characteristics of K2qn1 in the sag has not been carried out.
