Study on Wax Deposition Law in Daqing Gulong Shale Oil [PDF]

E3S Web of Conferences
Daqing Gulong shale oil exhibits elevated wax content, a high wax precipitation point, and a high freezing point. However, its oil density and viscosity are relatively low, making it susceptible to wax crystal precipitation. The risk of pipeline clogging

Optimizing Graphene Oxide Interlayer Spacing for Zeolitic Imidazolate Framework-8 Growth Toward Enhanced Shale Oil Separation. [PDF]

Adv Sci (Weinh)
Quaternary ammonium salts are used to control the spacing between GO layers, enabling in situ growth of ZIF‐8. The resulting ZIF‐8‐GO membrane exhibits nearly complete rejection of n‐docosane in n‐hexane, solvent permeance of 16.4 ± 0.8 L m−2 h−1 bar−1, and enriches alkanes and aromatics with a molecular weight cut‐off of 310 g mol−1 in shale oil ...

Evolution of Fractal Pore Structure in Sedimentary Rocks

Earth and Space Science, Volume 9, Issue 6, June 2022., 2022
Abstract Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure and fluid flow of rocks over time. This study presents experimental evidence to illustrate that the pore fractal structure evolves with sedimentation, carbonate cementation, clay growth, and dissolution.

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 ...
