Differences in Reservoir Formation and Main Control Factors of Bozhong 34-A Structure in Huanghekou Depression
In order to analyze the regional structure,reservoir distribution characteristics and their relationships based on drilling,3D seismic and logging data in BZ34-A oilfield,the control effects of fault combination pattern,fault activity and sand coupling on oil and gas distribution are systematically analyzed.First of all,the fault combination style and the activity control trap evolution characteristics;Secondly,the activity of the fracture system and the"time-space-source"coupling of hydrocarbon accumulation control hydrocarbon migration and accumulation.Finally,the fault-sand coupling controls the hydrocarbon differential distribution.
