POOL-FORMING MECHANISM OF THE XIAKOU FAULTED ZONE IN THE HUIMIN DEPRESSION

Based on the analysis of burial history,tectonic evolutionary history and stress-field evolutionary history,the contamination factors of mudstone and the normal stress of sections for different strike segments and different periods in the Xiakou faulted zone were calculated.Combined with the mechanical properties of faults and the relationship between fault moving periods and hydrocarbon migration periods,the fault sealing history of the Xiakou faulted zone was studied,and the pool-forming mechanism of the Xiakou faulted zone was remolded.
