Impact of fracturing fluid retention and flowback on development effect after large scale fracturing in shale oil wells: A case study from the shale oil of Chang 7 Member, Yanchang Formation, Ordos Basin Open
In order to reveal the impact of fracturing fluid retention and flowback on the development effect after large-scale fracturing in shale oil wells, and to formulate a reasonable flowback policy, this paper employs a combination of core phy…

A Form of Non-Volatile Solid-like Hexadecane Found in Micron-Scale Silica Microtubule Open
Anomalous solid-like liquids at the solid–liquid interface have been recently reported. The mechanistic factors contributing to these anomalous liquids and whether they can stably exist at high vacuum are interesting, yet unexplored, quest…

Experimental study on the effect of tube diameter on gas–liquid wettability in silica microtubules Open
In this paper, the gas–liquid static contact angles in silica microtubes (inner diameter range of 5–700 μm) are measured by optical microscope. The experimental results show that the gas–liquid contact angles in the microtube have microsca…

Applicability Analysis of Klinkenberg Slip Theory in the Measurement of Tight Core Permeability Open
The Klinkenberg slippage theory has widely been used to obtain gas permeability in low-permeability porous media. However, recent research shows that there is a deviation from the Klinkenberg slippage theory for tight reservoir cores under…
