Turbidite Fan Deposits in Gentle Slope Zones of Continental Faulted Basins: A Case Study from the Chezhen Depression, Bohai Bay Basin

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