Discussion on efficient exploitation technology of tight glutenite reservoir in Daqing

IOP Conference Series: Earth and Environmental Science, 2021
Abstract In XuShen gas field, due to the big lateral change of reservoir, accurately find the glutenite reservoir dessert area is difficult, Reservoir density and physical property is poor. Vertical Wells are the main wells in developed gas Wells, Inconsistent activity appeared in the process of mining action: high Shut-in pressure.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...
