“…1), Inner Mongolia, close to the border between China and Mongolia. It is an intracontinental basin formed during the Mesozoic continental extension of eastern Asia (Charles et al, 2013;Ren et al, 2002) and covering an area of approximately 130,000 km 2 (Dou and Chang, 2003;Wei et al, 2005). It is composed of five major sub-basins as following ( Fig.…”

“…It is composed of five major sub-basins as following ( Fig. 1): the Chuanjing Sub-basin to the West, the Wulanchabu Sub-basin in the central-west part, the Manite Sub-basin in the central-north, the Tengge'er Sub-basin in the southeastern part and the Wunite Sub-basin to the northeast (Dou and Chang, 2003;Dou et al, 1998;Wei et al, 2005). These sub-basins are framed by a series of horsts or ranges oriented ENE-WSW: the Daxing'anling Ranges to the East, the Bayinbaolige Horst to the North, the Suolunchan Horst more to the West and finally the Wendurmiao Horst to the South.…”

The Sunite Horst occupies the central part of the Erlian Basin and divides it into two different main parts (Dou et al, 1998;Wei et al, 2005), north and south (Dou and Chang, 2003). The Erlian Basin lies on a folded and metamorphized basement corresponding to the southern margin of the Xing'an or Xing Meng Mongolian Orogenic Belt (Dou and Chang, 2003).…”

“…The Sunite Horst occupies the central part of the Erlian Basin and divides it into two different main parts (Dou et al, 1998;Wei et al, 2005), north and south (Dou and Chang, 2003). The Erlian Basin lies on a folded and metamorphized basement corresponding to the southern margin of the Xing'an or Xing Meng Mongolian Orogenic Belt (Dou and Chang, 2003). This basement is mainly composed of both Paleozoic and early Mesozoic intermediate to felsic granitic plutons (Wu, G., et al, 2005;Wu et al, 2005a,b), mafic to felsic volcanic rocks (Chen and Chen, 1997;Ying et al, 2010) and Proterozoic to Paleozoic sedimentary or metasedimentary units (Wu, G., et al, 2005;Zhou et al, 2010).…”

“…This basin is divided into about 52 half-graben-shaped depressions (Dou and Chang, 2003;Meng et al, 2003) controlled by a normal-fault system and developed during three main stages: (i) a pre-rift stage mainly characterized by the emission of Late Jurassic to very Early Cretaceous volcanic rocks of the Qinganling Group (156.0-142.6 Ma; Chen and Chen, 1997;Graham et al, 2001;Wang et al, 2006), which corresponds to the initiation of the rifting; (ii) a syn-rift stage characterized by the deposition of Early Cretaceous sedimentary units (Cai et al, 1990;Gou et al, 1986;Sha, 2007): the Arshan Formation (K 1ba ) dominated by alluvial, fluvial and shallow lacustrine environments and the Tengge'er Formation (K 1bt ) dominated by deep to semi-deep lacustrine environment; and (iii) a post-rift stage characterized by a switch from tectonic to thermal subsidence and the deposition of the Early Cretaceous Saihan Formation (K 1bs ) mainly composed of sandstone and minor mudstone and the Late Cretaceous Erlian Formation (K 2e ) including a lower member dominated by sandstone and an upper member dominated by mudstone (Bonnetti et al, 2014). Sediments of both formations were deposited in fluvial and shallow lacustrine environments (Bonnetti et al, 2014;Currie and Eberth, 1993;Lin et al, 2001;Meng et al, 2003;Van Itterbeeck et al, 2005, 2007.…”

Relationship between source rock development and petroleum accumulation in the Erlian Basin, northern China

et al. 2018

View full text Add to dashboard Cite

The Wuli and Saihan sags in the Erlian Basin, the most petroliferous basin in northern China, were analysed with bulk geochemical analysis, carbon isotopic composition, microthermometry of fluid inclusions, and basin modelling to characterize the organic matter abundance and composition, to construct source rock development models, and to reveal the relationship between source rock development and hydrocarbon accumulation. The samples display wide variations in total organic carbon content and Rock‐Eval indices, suggesting heterogeneity of organic matter richness and type. The Wuli Sag has oxic depositional environment, high productivity, and high total organic carbon content; the effective oil source rocks are mainly distributed in the deep sag where the productivity is high; and there is plenty of organic matter left and preserved after degradation. In the Saihan Sag, there is a small amount of organic matter deposited because of low productivity; the effective oil source rocks are mainly distributed in the slope by the deep sag where the reducing degree is the strongest. The source rock development models controlled the geochemical characteristics and distribution of source rocks, which are the keys to hydrocarbon potential and accumulation. The oil of Wuli Sag is mainly distributed in the deep sag, whereas the oil of Saihan Sag is mainly distributed in the slope by deep sag, which is in agreement with the previously effective oil source rocks distribution. In the strong division sags, the region where source rock distributed is beneficial to hydrocarbon accumulation. The conclusions may have important implications for petroleum exploration in other small lacustrine depositional systems.

We conducted a study in the Wulan‐Hua Sag, a Mesozoic relic sag in the Erlian Basin to analyse and determine the period of its hydrocarbon accumulation. Estimation of erosional thickness is carried out from sonic well logs and seismic velocity data, followed by defining burial history of the Wulan‐Hua Sag together with thermal history through basin modelling. Fluid inclusions and pore fluid microthermometric data of 37 samples from clastic reservoir in the Wulan‐Hua Sag are available for detailed correlation and analysis. The reconstructed erosion thickness indicates that first of all, differential uplift that is characterized by seesaw uplift‐erosion initiated at the north sub‐sag. Secondly, largest erosion degree appears in Tumu'er and Saiwusu tectonic belts. Thirdly, the thickness of sedimentary rocks removed by erosion in the south sub‐sag progressively increases from its subsiding centre outwardly. Burial history of the Wulan‐Hua Sag belongs to type of late‐period intensive uplift‐erosion. Two types of fluid inclusion are recognized in the Wulan‐Hua Sag indicating two hydrocarbon accumulation periods for reservoirs in LK1bt1 (lower interval in first member of Tengge'er Formation), which is middle depositing period of K1bt1 (first member of Tengge'er Formation) to early depositing period of K1bt2 (second member of Tengge'er Formation) and early K1bt2 to middle K1bs (Saihantala Formation) depositing period, respectively. Reservoir in the K1ba and upper interval of K1bt1 appears to have experienced one hydrocarbon accumulation period, which is early K1bt1 to early K1bt2 depositing period. And reservoir in the UK1bt1 (upper interval in first member of Tengge'er Formation) also has one hydrocarbon accumulation period, which is late K1bt2 depositing period to the Late Cretaceous (K2). Hydrocarbon accumulation model of the Wulan‐Hua Sag consists of two oil‐reservoir types including “upward‐charging” and “self‐sourced.” Reservoir in lower interval of K1bt1 and reservoir in the upper interval of K1bt1 are considered to have more hydrocarbon exploration potential.
