Tectonic evolution and oil and gas of Tarim basin

Thermal evolution and maturation of lower Paleozoic source rocks in the Tarim Basin, northwest China

“…The basin is bounded by the Tian Shan Mountains to the north, the Kulugetake Mountains to the northeast, the Kunlun Mountains to the southwest and the Altun Mountains to the southeast (Figure 1). Numerous publications on the regional geologic setting of the Tarim Basin exist (Kang and Kang, 1996;Li et al, 1996;Jia and Wei, 2002;Dai et al, 2009;Yang et al, 2009). The basin has been divided into several structural zones, including four depressions and three uplift regions, that is, the Kuqa depression, the Northern depression, the Southwest depression, the Southeastern depression, the Northern uplift, the Central uplift, and the Southern uplift ( Figure 1).…”

“…These sediments have higher thermal conductivities than sandstone and mudstone and result in the relatively lower thermal gradients in these successions. The overlying Ordovician section is primarily composed of platform dolomite and marginal slope-shelf carbonate sediments (Kang and Kang, 1996;Jin et al, 2008). The upper Paleozoic marine and continental transitional sediments were accumulated after deposition of the Silurian and Devonian fine-grained red beds and sandstones.…”

“…The Tarim basin extends over an area of near to 0.8 × 10 6 km 2 , (Lithospheric Dynamic Atlas 1989). The Precambrian to Phanerozoic strata locally exceed 15 km in thickness (Yuzhu and Zhihong 1996; Jia et al . 1998; Guo et al .…”

“…The Tarim basin extends over an area of near to 0.8 × 10 6 km 2 , (Lithospheric Dynamic Atlas 1989). The Precambrian to Phanerozoic strata locally exceed 15 km in thickness (Yuzhu and Zhihong 1996;Jia et al 1998;Guo et al 2005). The basin is underlain by a 45 km deep Moho (data base of the Chinese Academy of Sciences, Institute of Geodesy and Geophysics), which deepens towards the northern, eastern and southern margins of the basin.…”

Oil charging history and pathways of the Ordovician carbonate reservoir in the Tuoputai region, Tarim Basin, NW China

“…1). The Tabei Uplift has undergone multistage tectonic events, including (1) the formation of the pre-Sinian basement and rift during the Sinian to Ordovician, (2) the formation of a paleo-uplift during the Silurian to Permian and its evolution (250-290 Ma), (3) the formation of a foreland basin during the Triassic to Jurassic period, (4) the extension of the basin during the Cretaceous to Neogene and (5) the rapid subsidence from the late Neogene to Quaternary (Kang and Kang 1996;Jia and Wei 2002;Jin et al 2008;Zhu et al 2011Zhu et al , 2013Fang et al 2016). The sedimentary successions of the Tabei Uplift are marine sediments (Sinian to Ordovician), marine-terrestrial transitional successions (Carboniferous to Permian) and terrestrial sequences (Triassic to Quaternary).…”
