Turbidite fans, serving as good reservoirs for petroleum accumulation, are typically formed during deep faulting periods in continental basins, particularly in steep slope zones. However, gentle slope zones are also significant and unique for the formation of turbidite fans. These turbidite fans hold immense importance in exploring concealed lithological reservoirs. Taking the Chezhen Depression of Bohai Bay Basin as an example, we conducted a comprehensive study of the turbidite fan deposits in the gentle slope zone. Our results indicate that (1) small-scale distal-source turbidite fans are a common sedimentary type in the Chezhen Depression of the Bohai Bay Basin; (2) the study area is mainly characterized by seven lithofacies; (3) there are incomplete Bouma sequences in the study interval. This study is an important turbidite investigation into continental faulted basins, and it can also provide an important reference value for exploration and development in unconventional reservoirs of the same type.

“…It is bordering on Chenjiazhuang uplift to the north, central uplift belt to the south, Qingtouzi uplift to the east, and Shengtuo Oilfield to the west (Figure 1). During the deep rift period, under the control of paleoclimate and water body variation, three sets of effective source rock measures with different lithological combinations and stratigraphic development features are formed in Mingfeng subsag (upper Sha4 submember, lower Sha3 submember, and middle Sha3 submember) [19]. The primary production zone of the Yonganzhen oil and gas field is the glutenite reservoirs of Paleogene Sha2 member (Es2) and upper Sha4 submemer (Es4s), while the significant production zone of the Yanjia oil and gas field is the glutenite reservoir of Sha3 member (Es3) and Sha4 member (Es4).…”

The identification of the oil-source correlation plays a significant role in petroleum exploration and development. In this study, we identify the oil-source correlation by a hierarchical cluster analysis method combined with traditional methods. The results shed light on the oil-source correlation in Minfeng area and revealed the oil migration and accumulation process. The crude oil in different structural belts and different horizons has different geochemical characteristics. According to the four types of crude oil and their planner distribution, it was considered that the crude oil mainly migrates along with favorable sand bodies and unconformity surfaces in the lateral direction and then charged and accumulated in the glutenite of Sha3 and Sha4 members since the area from sag to Yan Jia Oil and the gas field was lacking of oil source faults. Further analysis shows that the traps of fault blocks in Yong’anzhen are formed in the same phase, while the crude oil generated in the early stage is charged and accumulated in the fault block of the near source. Along with increasing of the buried depth of source rocks, the overlying source rocks gradually entered into the hydrocarbon generation phase, when crude oil started to charge in the fault blocks farther away.

“…Petroleum exploration is committed to identifying the spatial and temporal distribution of petroleum system elements (such as source, reservoir and transportation, etc.) to identify more oil and gas resources (Hu et al 2016(Hu et al , 2018Li et al 2020;Zhu et al 2020). However, the diversity of the underground world and the nature of its difficulty to observe directly surely increase the complexity of this work.…”

Estimation of base level changes in geological records is an important topic for petroleum geologists. Taking the Paleocene Upper Lingfeng Member of Lishui Sag as an example, this paper conducted a base level reconstruction based on Basin Filling Modelling (BFM). The reconstruction was processed on the ground of a previously interpreted seismic stratigraphic framework with several assumptions and simplification. The BFM is implemented with a nonlinear diffusion equation solver written in R coding that excels in shallow marine stratigraphic simulation. The modeled results fit the original stratigraphy very well. The BFM is a powerful tool for reconstructing the base level, and is an effective way to check the reasonableness of previous interpretations. Although simulation solutions may not be unique, the BFM still provides us a chance to gain some insights into the mechanism and dynamic details of the stratigraphy of sedimentary basins.
