Paleo-heat flow evolution of the Tabei Uplift in Tarim Basin, northwest China

Stratigraphic thermohistory and its implications for regional geoevolution in the Tarim Basin, NW China

“…On the other hand, considering the variation of telluric heat flow with time over geological history, BasinMod-1D numerical modeling software can be used to reconstruct the burial and thermal histories of both the wells. This method has yielded the denuded thicknesses of 4000 and 4100 m for the same interface [13]. Although there are some differences between the two methods, both indicate that the denuded thickness of the C 1 b/O 3 unconformity interface should exceed 4000 m, similarly questioning the paleouplift-depression relationship between the Tabei Uplift and Manjiaer Depression.…”

Estimation of subsurface formation temperature in the Tarim Basin, northwest China: implications for hydrocarbon generation and preservation

“…Although most area of the Tarim Basin is covered by the Cenozoic Taklamakan Desert, with only limited outcrops available along its margins, several important tectonic and thermal events have been identified Li et al 2010;Shu et al 2011;Zhang et al 2013), among which the early Permian intraplate basaltic magmatism is regarded as the largest one in terms of volume and spatial distribution, covering most of the basin with a total extent of over 250,000 km 2 ). However, this magma activity not only accelerated the thermal evolution of the Lower Paleozoic source rocks from mature into overmature, but also introduced enormous magmatic emplacement and eruption, which had destroyed the previously formed oil and gas reservoirs (Wang et al 1992b;Chen et al 1997).…”

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

“…5, Table 1), indicating that they derived from a different oil family. Previous reports showed that oils in these wells derived from Cambrian-Lower Ordovician source rocks (e.g., Li et al 2010aLi et al , b, 2012Li et al , 2015Song et al 2016). …”

“…Two typical oil samples collected from Wells TD2 and T904 were also analyzed for comparison. Oils in these two wells are considered to be sourced from Cambrian-Lower Ordovician source rocks (Ma et al 2005;Zhang and Huang 2005;Li et al 2010aLi et al , b, 2012Li et al , 2015Song et al 2016). …”
