“…The ancient redox conditions are mainly related to the content of free oxygen in the lake water, and the redox properties of the water are mainly characterized by the ratio of V/(V + Ni), Ni/Co and U/Th elements (Flemming, 2000;Nwaezeapu et al, 2018). The V/(V + Ni) ratios of this sample all ranged from 0.69 to 0.76, with an average of 0.73.…”

“…In the sequence framework, fine-grained sediments often develop in the transgressive system tract (TST) or the early highstand system tract (LHST) and have different differences in different system tracts. The lithofacies characteristics (Cather et al, 2021;Lapidus, Kerimov, Mustaev, Movsumzade, & Zakharchenko, 2018;Leven, 2013;Nwaezeapu et al, 2018;Zhang, Bai, Jin, & Wang, 2016). Hemmesch, Harris, Mnich, and Selby (2014) studied the distribution characteristics of the minerals and lithofacies of the Woodford Shale in the Permian Basin and found that the high stand system tract (HST) developed mudstone and carbonate interbeds, and the TST developed organic-rich shale (Hemmesch et al, 2014).…”

“…With the development of reservoir characterization and special mining techniques, the characteristics of fine‐grained sedimentary rocks as reservoirs have been revealed, and their huge oil and gas resource potential has been confirmed. Therefore, fine‐grained sedimentary rocks, especially organic‐rich shales with integrated source and storage rock has received increasing attention from industry and academia (Aplin & Macquaker, 2011; Bechtel et al, 2012; Birdwell & Washburn, 2015; Liu et al, 2020; Mussa, Kalkreuth, Pimentel Mizusaki, & Bicca, 2021). Fine‐grained sedimentary rock refers to clay‐grade and silt‐grade sediments (particle size less than 65 μm), Usually contains mudstone, shale, argillaceous siltstone, and siltstone (Bechtel et al, 2012; Cichon‐Pupienis et al, 2021; Li & Schieber, 2018; Ross & Bustin, 2008; Trabucho‐Alexandre, Dirkx, Veld, Klaver, & De Boer, 2012).…”

The second Member of the Funing Formation in the Haian Sag of the Subei Basin is a set of organic-rich fine-grained sedimentary rocks, which is a key interval for shale oil exploration. Under the premise of establishing a high-frequency sequence framework, the fine description of the lithofacies change characteristics of the continental fine-grained sedimentary rocks is the basis for the prediction of shale oil favourable areas and the optimization of the production horizons. This study is established through wavelet transformation of the natural gamma curve of the high-frequency sequence framework of the second Member of the Funing Formation, using thinsection observation, total organic carbon analysis, and X-ray diffraction experiments to study the lithofacies types and characteristics of fine-grained sedimentary rocks, and discuss the combination of lithofacies under the high-frequency sequence framework Mode and influencing factors. The results show that the second Member of Funing Formation is composed of three-level sequence of low-level system tract (LST), transgressive system tract (TST), and early high-level system tract (EHST), corresponding to 6 fourth-level sequences and 10 fifth-level sequences. According to the division scheme of "abundance of organic matter + mineral composition + sedimentary structure", it is found that 12 types of lithofacies were developed in the fine-grained sedimentary rocks of the second Member of Funing Formation. The lithofacies type is affected by the palaeoenvironment. The organic matter facies are mainly controlled by palaeo-water depth and palaeo-redox conditions, the components are mainly controlled by palaeo-water depth and palaeo-salinity, and the tectonic facies are mainly controlled by palaeo-redox and palaeo-salinity. The lithofacies are regularly superimposed in the high-frequency sequence framework, and three combination modes of A, B, and C are developed. Among them, the type A lithofacies are developed in the low-stand system tract, and the type B lithofacies are developed in the transgressive system. The C-type lithofacies assemblage developed near the largest flooding surface and the early highstand system tract, and combined with palaeoenvironment analysis to establish a lithofacies sedimentary model.

Formation water (FW) and fracturing fluid (FF) significantly affect the adsorption rules of CH4 on a shale surface. To clarify the impact rules and micromechanisms of FW and FF on CH4 adsorption, isothermal adsorption experiments of CH4 on different shale minerals with different equilibrium water were conducted. Then, the corresponding adsorption models were constructed by Grand Canonical Monte Carlo (GCMC) simulation to perform adsorption simulation after matching experiments. Finally, molecular dynamic (MD) simulation was carried out to study the micromechanisms of FW and FF affecting CH4 adsorption on different shale minerals. The results show that the adsorption capacity of organic matter to CH4 is much stronger than that of other minerals. Compared to dry conditions, the adsorption capacity of organic matter, smectite, illite, and total shale with FW (S w ≈ 15%) decreases to 65, 45, 70, and 55%, respectively. The impact of FF on CH4 adsorption capacity is more significant than FW. The adsorption capacity decreases to 45, 30, 50, and 45% for organic matter, smectite, illite, and total shale with FF (S w ≈ 15%), respectively. FW molecules inhibit CH4 adsorption by occupying adsorption sites on mineral surfaces. However, the HPAM in FF completely covers the mineral surface to compress adsorption space and hinder CH4 adsorption. Although water molecules in both FW and FF occupy part of the adsorption sites on organic matter, the left sites can still absorb large amounts of CH4. It provides theoretical guidance for the efficient development of shale gas.
