During the soaking process of shale gas reservoirs, due to the imbibition of fracturing fluid
and the dissolution of solid substances in the reservoir, the flowback rate is low, and the …

Spontaneous imbibition is significantly influenced by rock wettability, and it has been
extensively studied in core-based experiments and numerical simulations owing to its …

Previous research has confirmed that substantial yield has been recovered in the soaking
period after hydraulic fracturing. Spontaneous imbibition (SI) is the primary mechanism …

The heterogeneous-wet state within oil and gas reservoirs introduces complex fluid
distribution and flow dynamics, which significantly impacts enhanced oil recovery and geo …

Spontaneous imbibition plays an important role in many practical processes, such as oil
recovery, hydrology, and environmental engineering. The development in spontaneous …

渗吸驱油是裂缝性油藏的有效驱油方式, 但渗吸驱油的机理一直没有得到统一的认识,
应用相关知识对其进行深入研究, 取得以下认识. 渗吸有同向渗吸和逆向渗吸之分 …

The petrographic study of organic matter (OM) in fine-grained, shale and tight rocks can be
complicated by ambiguities in distinguishing primary kerogen (deposited OM) from …

Many naturally occurring porous media contain different types of grains with different
wettabilities, therefore, understanding the effect of wettability heterogeneity on multiphase …

The basic performance of a novel high-efficiency spontaneous imbibition agent (SXJ-2) was
investigated in this study. The mechanisms of spontaneous imbibition and wettability …

Mercury injection capillary pressure (MICP) analysis was used to study organic-matter-rich
Devonian shales varying in maturity from marginally mature to postmature to discuss …
