Study on Multi-Element Coupled Hydrocarbon Migration Model of Cretaceous Qingshuihe Formation in Block 3,Central Junggar Basin
摘要
Abstract
The accumulation and differential distribution of hydrocarbon in the Cretaceous Qingshuihe formation in Block 3 in central Junggar Basin mainly depend on the three-dimensional spatial configuration of the compos-ite transport system of fault-weathering leach zone,sand-body and unconformity,in which the fault system and weathering leach zone dominate the vertical migration and multi-zone adjustment,while the sand-body and uncon-formity plane control the dominant lateral migration path.Based on the characterization and spatial configuration combination of transport systems such as bottom conglomerate,unconformity,weathering leach zone and fault,the spatial coupling relationship between storage layer(bottom conglomerate,unconformity plane,weathering leach zone)and reservoir forming elements are defined.Three hydrocarbon migration modes of Qingshuihe formation are established,including the A-type fault-assisted upper storage(fault-assisted,lateral escape,upper reservoir for-mation),B-type carpet sand storage(horizontal closure,carpet sand accumulation),C-type fault-assisted blanket sand storage(fault-assisted,lateral containment,blanket sand accumulation).These systematically elucidate the controlling effect of the migration mode on oil and gas,and the spatial evolution law.关键词
