Imbibition and Oil Recovery Mechanism of Fracturing Fluids in Tight Sandstone Reservoirs [PDF]
ACS Omega, 2021 The fracturing fluid residing in a reservoir undergoes spontaneous imbibition. Here, to explore the mechanism of fracturing fluid imbibition and oil displacement, experiments on the spontaneous imbibition of fracturing fluid under different influencing factors were conducted on a core sample from the Ordos Basin of the Chang 8 formation.

Analysis of pore throat characteristics of tight sandstone reservoirs [PDF]
Open Geosciences, 2020 Abstract The characterization of pore throat structure in tight reservoirs is the basis for the effective development of tight oil. In order to effectively characterize the pore -throat structure of tight sandstone in E Basin, China, this study used high-pressure mercury intrusion (HPMI) testing technology and thin section (TS ...

Optimization of fracturing parameters for tight sandstone gas reservoirs
IOP Conference Series: Earth and Environmental Science, 2021 Due to the poor physical properties of tight sandstone, the pore throat is small and the connectivity is poor. In the process of development, fracturing construction is often needed. Reasonable fracturing construction parameters are the key and difficult points of fracturing design, and also the key factor to determine the success of fracturing. Aiming

The impacts of diagenetic facies on reservoir quality in tight sandstones [PDF]
Open Geosciences, 2020 Abstract The impact of diagenetic minerals and the characteristics of pore structures on reservoir qualities has been studied separately in the past years. However, the difference in the reservoir quality with different pore structures and having same or similar content of diagenesis minerals has not been ascertained.
