“…The upper Carboniferous Taiyuan Formation is composed of coal-bearing strata deposited in a marine-continental transitional environment. The distribution of this formation is controlled by the Porjianghaizi fault, Sanyanjing fault and Wulanjilinmiao fault, and the formation is exposed mainly to the south of these faults in areas that include the Yishan slope and Tianhuan depression (Yang et al, 2015).…”

Collapsed reflections of lower Ordovician carbonates and upper Carboniferous-lower Permian coal-bearing strata occur below the middle Permian lower Shihezi Formation in the Hangjinqi area, northern Ordos Basin. This study takes advantage of three-dimensional seismic data, logging data, core data and well-testing data to investigate the genesis of the collapsed reflections and their implications for hydrocarbon potential. These collapse structures have a subcircular appearance in map view. The columnar reflections in the basement and the volcanic tuff in the lower Shihezi Formation around collapse structures indicate that the formation of these structures are related to magmatic activity. Most of the collapse structures terminate upward in the H1 member of the lower Shihezi Formation, which explains its greater thickness and supports the hypothesis that magmatic activity occurred during the depositional stage of the lower Shihezi Formation in the early middle Permian. The collapse structures can increase the thickness and space of the reservoirs, and the collapse of magma conduit can also increase the thickness of the regional sedimentary cap rock above the collapse structures and improve the sealing capacity of the cap rock. These results provide insights into the magmatic activity and hydrocarbon potential of Paleozoic rocks in the Ordos Basin.

“…The geological reserves of tight gas in the Hangjinqi area are higher than 700 × 10 9 m 3 , and the Upper Paleozoic tight gas reservoirs are characterized by the lithological traps, large gas-bearing area, and low abundance of reserves [31]. Previous studies have been conducted on the Mesozoic tectonic evolution [32], segmentation of the faults [33], geochemical characteristics of the source rocks [34,35], and the origin of natural gas [36]. Moreover, Hao et al [31] demonstrated the forming conditions of the gas reservoirs, and Wang et al [37] proposed the accumulating mechanism of natural gas based on the analysis of trap conditions.…”

The molecular and stable isotopic compositions of the Upper Paleozoic tight gas in the Hangjinqi area in northern Ordos Basin were investigated to study the geochemical characteristics. The tight gas is mainly wet with the dryness coefficient (C 1 /C 1-5 ) of 0.853-0.951, and 13 C 1 and 2 H-C 1 values are ranging from −36.2‰ to −32.0‰ and from −199‰ to −174‰, respectively, with generally positive carbon and hydrogen isotopic series. Identification of gas origin indicates that tight gas is mainly coal-type gas, and it has been affected by mixing of oil-type gas in the wells from the Shilijiahan and Gongkahan zones adjacent to the Wulanjilinmiao and Borjianghaizi faults. Gas-source correlation indicates that coal-type gas in the Shiguhao zone displays distalsource accumulation. It was mainly derived from the coal-measure source rocks in the Upper Carboniferous Taiyuan Formation (C 3 t) and Lower Permian Shanxi Formation (P 1 s), probably with a minor contribution from P 1 s coal measures from in situ Shiguhao zone. Natural gas in the Shilijiahan and Gongkahan zones mainly displays near-source accumulation. The coal-type gas component was derived from in situ C 3 t-P 1 s source rocks, whereas the oil-type gas component might be derived from the carbonate rocks in the Lower Ordovician Majiagou Formation (O 1 m).
