“…The natural gas is sourced coal gas with a heavier carbon isotope [23]. Zhu et al [24] regarded the Dibei gas field as a condensate gas reservoir with normal temperature (approximately 116-135 ∘ C) and overpressure (pressure coefficient of about 1.43-1.87 reactive to hydrostatic pressure).…”

“…With the development of petroleum exploration and exploitation, deep (3500–4500 m) to ultra-deep (> 4500 m) tight sandstone has been paid more attention because of its abundant oil and gas resources 1 , 2 . The deep and ultra deep clastic reservoir is characterized by strong reservoir heterogeneity and complicated reservoir-forming characteristics for its high degree of diagenetic stage and the complexity of diagenesis 3 5 . Considerable efforts have been made to understand the spatial and temporal distribution of diagenesis in clastic rocks, maily due to the realization that these alterations exert profound controls on reservoir quality 6 – 9 .…”

“…. In BP1 stage, the CUB I has the fastest burial rate with 163 5. 202.2 m/Ma, followed by CUB II with 145.8 m/Ma and WS with 114.3-174.1 m/Ma, and WSB and CUB III have the slowest burial rate, with 119.1-142.8 m/Ma and 55.3-165.1 m/Ma respectively; In BP2 stage, WS burial rate is 332.4-501.3 m/Ma, followed by CUB I with 300.8-442.3 m/Ma, and WSB with 329.7 to − 472.8 m/Ma, and CUB II and CUB III have the slowest burial rate, with 356.9 m/Ma and 297.9-356.9 m/ Ma respectively; In BP3 stage, CUB uplift rate is − 202.3 to − 281.8 m/Ma, followed by CUB III with − 170.5 to − 178.3 m/Ma.…”

“…The Kuqa Depression, which is located in the north part of the Tarim Basin, north western China, is an area with hydrocarbon-rich resources and broad prospects. Large gas fields, such as Kela 2, Dabei, Keshen, and Bozi have been recently exploited in Cretaceous and Paleogene sandstone reservoirs (Gao et al., 2018; Wei et al., 2019; Zhang et al., 2011; Zhu et al., 2015). The latest explorations indicate that the ultra-deep layer (burial depth > 6000 m) of the Kuqa Depression shows the potential of trillion cubic meters of natural gas, which is one of the most realistic areas for increasing reserves and production in the Tarim Basin (Yu et al., 2019).…”

“…The Dabei Gas Field is located in the western portion of the Kuqa Depression; the geochemical features and origins of hydrocarbon in this area have been widely studied (Dai et al., 2001; Guo et al., 2016a; Zhu et al., 2015). Natural gases are dominated by methane (>85%) and also contain a minor content of heavy hydrocarbon (C 2+ ), and the other components are mainly N 2 and CO 2 .…”
