Formation changes and structural mutation were found in part of adjacent wells in the production process of Chang 9 reservoir in Jiyuan Oilfield. By seismic interpretation, strata correlation and core observation, 21 NWW normal faults developed in Jiyuan area were found. The time and space of Tianhuan Depression and hydrocarbon-generating peak of Chang 7 hydrocarbon-generating rocks are matched, which promotes the hydrocarbon lateral migration and accumulation, so the reservoir is relatively enriched in eastern part of the depression. The reservoir was readjusted after fault formation, which results in the destruction of reservoir belowthe faults.
