“…During the Late Cretaceous, the OB was uplifted, resulting in a plateau (Zhang et al, 2017). However, due to large-scale strike-slip events during the Cenozoic Era, the OB was separated from the NCB, and numerous graben structures were formed around the basin (Zhang et al, 1998;Liu et al, 2020). The basin consists of six tectonic regions and five secondary structural regions characterized by fluctuations in the structure at the top surface of the basement (Wu et al, 2017).…”

“…The basin consists of six tectonic regions and five secondary structural regions characterized by fluctuations in the structure at the top surface of the basement (Wu et al, 2017). The six tectonic units include Weibei uplift, Yimeng uplift, Western edge overthrust belt, Jinxi flexural belt, Yishan ramp, and Tianhuan depression (Hao et al, 2007;Liu et al, 2020). The study area of Hangjinqi is situated at the junction of the Yishan ramp and Yimeng uplift.…”

“…From the west to east region of the study area, three main faults are disseminated named as Wulanjilinmiao fault, Sanyanjing fault, and Porjianghaizi fault (PF) (also referred to as Boerjianghaizi fault in the literature) (Wu et al, 2017). These three faults have W-E to SW-NE dipping orientations (Liu et al, 2020). The PF is the main and the largest fault that separated the Hangjinqi area into north and south regions.…”

“…Numerous faults were established, which made the study area more complicated. Former studies conducted within the study area were focused on the structural evolution (Yang et al, 2015a;Yang et al, 2015b), tectonic controls (Liu et al, 2020), channel identification (Anees et al, 2019;Anees et al, 2022), evaluation of genetic types and source of Upper Paleozoic tight gas (Wu et al, 2017), hydrothermal mineralization of uranium deposits (Zhang et al, 2017), and evaluation of clay mineral content, and type of reservoir properties (Wang et al, 2020).…”

The Hangjinqi area was explored for natural gas around 40 years ago, but the efficient consideration in this area was started around a decade ago for pure gas exploration. Many wells have been drilled, yet the Hangjinqi area remains an exploration area, and the potential zones are still unclear. The Lower Shihezi Formation is a proven reservoir in the northern Ordos Basin. This study focuses on the second and third members of the Lower Shihezi Formation to understand the controlling factors of faults and sedimentary facies distribution, aimed to identify the favorable zones of gas accumulation within the Hangjinqi area. The research is conducted on a regional level by incorporating the 3D seismic grid of about 2500 km2, 62 well logs, and several cores using seismic stratigraphy, geological modeling, seismic attribute analysis, and well logging for the delineation of gas accumulation zones. The integrated results of structural maps, thickness maps, sand-ratio maps, and root mean square map showed that the northwestern region was uplifted compared to the southern part. The natural gas accumulated in southern zones was migrated through Porjianghaizi fault toward the northern region. Well J45 from the north zone and J77 from the south zone were chosen to compare the favorable zones of pure gas accumulation, proving that J45 lies in the pure gas zone compared to J77. Based on the faults and sedimentary facies distribution research, we suggest that the favorable zones of gas accumulation lie toward the northern region within the Hangjinqi area.

“…After the Caledonian movement uplifted, Eastdipping gentle slope tectonic pattern continued until Jurassic. The uplift amplitude in the eastern part of the basin was stronger than that in the western part due to the Yanshan movement and Himalayan movement, then the western dipping monoclinal structural framework was formed and has been extended to the present day (Liu et al, 2020;Shu et al, 2019). The stratum are developed in the Lower Paleozoic Cambrian and Ordovician, the Upper Paleozoic Carboniferous and Permian, the Mesozoic Triassic, Jurassic, Cretaceous and the Cenozoic Quaternary, while the Silurian, Devonian, Paleogene and Neogene are missing.…”

Characteristics of complex gas-water distribution affect the efficient exploration of tight gas. The paper aims at tight sandstone gas-water distribution characteristics of He8 Member in Sulige Gas Province (SGP), describes thickness and TOC of source rocks from Benxi Formation in Carboniferous to the Second Member of Shanxi Formation in Permain, evaluates its hydrocarbon generation potential, discusses its controlling effect on tight sandstone gas-water distribution, and determines the threshold values of Ro and HGI of commercial gas flow wells. Research shows that the coal-measure source rock has the characteristics of extensive and superimposition. The coal seam and dark mudstone is the lithology of source rock, and its Ro is chiefly distributed 1.2% ∼ 2.1% in the stage of high mature thermal evolution, which is mainly type III kerogen. Among them, the thickness of coal seam is mainly ranged from 5 ∼ 15 m with an average of 9.32 m, and its average TOC is 64.08% and the distribution of HGI is (1∼36) ×108 m3/km2. No.8 and No.5 coal seams are relatively stable. The extent of thickness of dark mudstone is mainly between 10m and 30m with an average of 21.2m, and its average TOC is 2.11%, HGI is between (0.2∼10)×108m3/km2. Gas reservoir of He8 Member is tight sandstone lenticular reservoirs with the large-area quasi-continuous distribution. When the gas testing production is less than 1 × 104m3/d, the controlling effect of Ro and HGI are relatively obvious, and its controlling effect is obviously weakened with the increase of gas production. When Ro is more than 1.6%-1.7%, or HGI is larger than 15 × 108m3/km2, the decreasing trend of water/gas ratio is evident, especially in commercial gas flow wells (including high producing gas flow wells). In comparison, the controlling effect of HGI is stronger than Ro. 1.33% and 8 × 108 m3/km2 are the threshold values of Ro and HGI for commercial gas flow wells, respectively.
