  • Analyses of seismic profile and fault assemblage indicate that the horizontal distribution char acteristics of faults in the east,center and west of Kongquehe region are different.The western faults are mainly EW oriented and arrayed in right enechelon formation.The central faults are mainly NNE oriented and arrayed in parallel formation.The eastern faults are mainly NW-EW oriented and arrayed in left en-echelon formation.Based on analyses of balanced cross section,the tectonic evolution histories of different zones of Kongquehe region were studied.Combined with typical accumulation characteristics,it was concluded that the region favorable for petroleum accumulation located in where Paleozoic was weakly eroded and Mesozoic uplifted,and the region should be neighboring to active faults which lead to petroleum sources.Favorable exploration targets were also pointed out.
