“…NNE-and NNW-trending conjugate-slip faults have developed in the Tabei Uplift that cut each other like a checkerboard lattice, north to the Luntai Fault and south to the Shunbei No.1 Fault (Lv et al, 2017;Zhang et al, 2020). Combined with previous studies and seismic profile analysis, NNE-and NNW-trending conjugate-slip faults dominate the Tuoputai region.…”

Exploration potential is huge and the oil resources are rich in the Ordovician reservoirs of the Tarim Basin. However, the mechanism of hydrocarbon accumulation is complex and not yet fully understood. In the Tuoputai area, the hydrocarbon migration pathways and characteristics of deep hydrocarbon accumulation are revealed through analyses of the physical data of rich oil and gas, the geochemical parameters of oil, and fluid inclusions. The results show that the Ordovician oils in the Tuoputai area have the same geochemical characteristics as the mixed oil from the Lower Cambrian source rock and the Middle–Upper Ordovician source rock. The Ordovician reservoirs have been charged three times: in the late Caledonian, late Hercynian, and Himalayan stages. Oil charging occurred in the Hercynian stage, in particular, as it is the main filling period of hydrocarbon. The north‐northeast (NNE)‐trending TP12CX major fault, active in in these times and is dominant migration channel of hydrocarbon, but there is segmentation affected by the difference of activities. Oil maturity is higher in the south than in the north and is abnormally high near the major fault. Parameters related to migration indicate that oil migrated northeastward along the NNE‐trending TP12CX major fault and adjusted laterally along the secondary faults and weathering crust, forming the present characteristics of oil and gas distribution.

“…Currently, the most mature methods for studying the characteristics of fault activity are the paleo-drop method and the growth index method [40][41][42] . The balanced cross-section and structural physical simulation methods are frequently utilized to investigate tectonic evolution and genetic mechanism [43][44][45][46] .…”

This study used the growth index, fault activity rate and fault distance burial depth curve methods to analyze the characteristics of fault activity in the central area of Dongying depression. Using typical fault evolution and dynamic analysis to study the stages of fault evolution in the area, and using physical simulation experiments to study the mechanism and evolution process of fault formation. According to the results, the faults in the study area can be classified into four types. The Shicun fault and the pre-existing faults in the basin developed in the Paleogene Kongdian to Es4 period. Es3x and Es3z stages were characterized by strong extensional fault activities. The effect of strike-slip transformation from the Es3s to Es1 period was strengthened. The extensional fault continued to be active in Dongying period, and the strike-slip fault was basically stopped. The study area has been in the depression stage since Neogene. The physical simulation experiments show that the northern He 125 fault system is a fault combination composed of a main fault and broom-shaped branches formed by normal fault activities in the early stages and dextral strike slip processes in the late periods. The central en echelon fault system is a fault combination composed of three R fractures inherited the NE-SW basement fault and regulated by the later dextral strike-slip activities. The southern Wangjiagang fault system is a complex fault combination composed of Wangjiagang structure (P fracture) and Bamianhe structure (R fracture) developed from the Tanlu concealed branch strike-slip fault. This paper provided important reference for further research on the tectonic evolution and hydrocarbon accumulation in Dongying depression.

“…The Tazhong Uplift mainly underwent mixed accumulation of high-over mature cracking gas and early reservoirs. The NE-trending strike slip fault was the main transportation system (Zhang et al, 2020), particularly affecting the migration and distribution of the late cracking gas. Furthermore, the NEtrending strike slip fault connected the hydrocarbon sources and reservoirs of the Lower Ordovician-Cambrian dolomite and granular beach, thereby constructing another favorable deep exploration field around the platform margin.…”

The Tarim Basin is the only petroliferous basin in China where marine industrial petroleum has been explored and developed. After 30 years of exploration, the marine reserves have reached more than the equivalent of 4.68 billion tons of oil, with an annual production capacity equivalent to 12.8 million tons of oil (Yang et al., 2020). The Tarim Basin has been promoted as the most important production base of marine petroleum in China. Since the exploration breakthrough of Well SC-2 in the Tabei Uplift, commercial reserves have been discovered in eight strata from the Cambrian to the Cretaceous. The hydrocarbon reservoirs were mainly accumulated in the Ordovician, including dry gas, condensates, light oil, waxy oil, heavy oil and oil sand.A large number of geochemical studies show that ∈-O 1 and O 2-3 are the main marine source rocks (SRs) of the Tarim Craton Zhang et al., 2004).According to the oil-source correlation of the specific biomarkers, such as dinosterane, 4-methyl-24 ethylcholestane and 24-norcholestane, it was determined that the genesis of most reservoirs in the uplift was mainly related to O 2-3 SRs (Zhang et al., 2000Ma et al., 2006;Li et al., 2010). Only some hydrocarbon reservoirs, such as the heavy oil reservoir in Well TD-2 (∈), condensate reservoirs in Well YN-2 (J) and normal oil reservoirs in Wells-TZ62 (S) and Th904 (O) possess geochemical characteristics similar to Cambrian SRs. Due to the light hydrocarbon fingerprints, tricyclic and tetracyclic terpanes, aromatic isoprenoids and sulfur isotopes, some researchers believe that most marine oils in the Tarim Basin more closely resemble ∈-O 1 SRs (Zhao and Huang, 1995;Sun et al., 2003;Cai et al., 2015).With the constant expansion of exploration, newly discovered reservoirs have mainly been found in the slope
