Geological and Geochemical Characteristics of the First Member of the Cretaceous Qingshankou Formation in the Qijia Sag, Northern Songliao Basin, Northeast China: Implication for Its Shale Oil Enrichment

open access: yesGeofluids, 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.

Study on Hydraulic Fracture Propagation of Strong Heterogeneous Shale Based on Stress‐Seepage Damage Coupling Model

open access: yesEnergy Science &Engineering, Volume 13, Issue 1, Page 309-322, January 2025.
The stress model of rock in the hydraulic fracturing process is developed to study the behavior of hydraulic fracture propagation in strong heterogeneous shale under the coupled action of stress and seepage. In heterogeneous shale reservoirs, strong heterogeneity is the main factor limiting the height propagation of hydraulic fractures.
