“…A lot of research has focused on pore-throat structures, development environments, and distributions of tight oil reservoirs in multiple regions (Liang et al 2011;Kuang et al 2012;Zhou and Yang 2012;Yang et al 2013;Zhang et al 2013;Pang et al 2015). However, scholars have showed less concern about tight oil plays, since they believe that tight oil accumulated near or in source formations (Jia et al 2012;Zou et al 2014).…”

Multiple-stacked Hybrid Plays of lacustrine source rock intervals: Case studies from lacustrine basins in China

Hydrocarbon-producing lacustrine basins are widely developed in the world, and China has a large number of lacustrine basins that have developed since the early Permian. The organic-rich shale-dominated heterogeneous source rock intervals in Chinese lacustrine basins generally contain frequent thin interbeds of stratigraphically associated sandstone, siltstone, marl, dolomite, and limestone. The concept of ''Hybrid Plays'' as put forth in this article recognizes this pattern of alternating organicrich shale and organic-lean interbeds and existence of mixed unconventional and conventional plays. Hybrid Plays in lacustrine source rock intervals present a unique closed petroleum system hosting continuous hydrocarbons. The interbedded organic-lean siliciclastic and/or carbonate plays are efficiently charged with hydrocarbons via short migration pathways from the adjacent organic-rich shale that is often also a self-sourced play. We assert ''Hybrid Plays'' provide the most realistic exploration model for targeting multiple-stacked and genetically related very tight shale, tight and conventional plays together in the entire source rock interval rather than individual plays only. The Hybrid Play model has been proven and works for a wide variety of lacustrine rift, sag and foreland basins in China.

“…It is a main supply area of traditional energy such as oil and gas and an important area of unconventional energy such as shale gas and tight oil in China (Jia, Zheng, & Zhang, ; Jin & Cai, ; Kang, ; Li, Santosh, & Jahn, ; Zhao, Zheng, & Zhang, ; Zou et al, ). Currently, several oil and gas exploration, exploitation, and production bases are constructed in the Ordos Basin, such as Mesozoic tight oil field (Guo et al, ; Jia, Zou, Li, Li, & Zheng, ; Lai, Wang, Ran, Zhou, & Cui, ; Li et al, ; Li, Guo, Yang, & Wang, ; Ren et al, ; Yang, Li, & Liu, ; Yao et al, ; Yao et al, ; Zhao et al, ), Upper Paleozoic tight oil field (Chen et al, ; Fu, Wei, Ren, & Zhou, ; Hu, Li, Shan, & Han, ; Li, Di, & Xi, ; Liu et al, ; Liu, Sun, Zhao, Wang, & Wu, ; Ren, Zhang, Ezekiel, Ren, & Meng, ; Yang & Wei, ), and Shaanxi shale gas demonstration base (Guo et al, ; Ji et al, ; Tang et al, ; Wang, ; Wang et al, ; Xu & Bao, ). The Ordos Basin enriches Mesozoic oil resources and Paleozoic natural gas resources, so it has a great exploration and exploitation potential (Chen et al, ; Li et al, ; Liu et al, ; Ren, ; Wang & Wang, ).…”

Tectonothermal evolution has an important control on maturity and hydrocarbon‐generation of source rocks. On the basis of analysis of the present‐day geothermal gradient, rock thermophysical parameters and heat flow, the thickness contour and vitrinite reflectance can be identified, and the distribution of thermal anomaly was discussed. The paleogeotemperature and paleogeothermal gradients are calculated after the recovery of the erosional thickness. With the theory of the recovering of the superposed and modified sedimentary basin, the evolutionary history since the end of Triassic, the end of Jurassic, the Late Early Cretaceous is presented for two sets of source rocks recovered in various perspectives of plans, cross‐sections, important wells, and typical areas. The impact of tectonothermal evolution on the maturity and hydrocarbon‐generation history of the source rocks is discussed. The paleogeothermal gradient (4.0 °C/100 m on average) is higher than the present one (2.9 °C/100 m on average). With the slightly continuous increase since the Late Paleozoic, the paleogeotemperature of the Ordos Basin reached its maximum in Late Early Cretaceous and decreased continuously from then on. The paleogeotemperature and maturity of the source rocks continuously increased before Late Early Cretaceous. The tectonothermal event during Late Jurassic to Early Cretaceous controlled the source rocks with the high temperature and maturity in the Wuqi‐Qingyang‐Fuxian. The temperature decreased, and the maturity hardly changed after the Late Cretaceous. The source rocks of the Shanxi Formation reached maturity, high maturity and over‐maturity at the Late Triassic, the Late Jurassic, and the Early Cretaceous, respectively. The source rocks of the Yanchang Formation reached low maturity and maturity sequentially all in the Early Cretaceous.
