辽东湾地区油气运移输导体系特征及意义

砂体、断层、不整合面是辽东湾地区油气运移的基本要素，它们之间相互配合形成三类油气运移输导体系。以断层为垂向运移通道的油气藏常在断层带附近多层叠置，且断层多具有同生性质

THE CHARACTER AND SIGNIFICANCE OF HYDROCARBON TRANSFERING SYSTEM IN LIAODONG BAY

The faults，san bodies and unconformities，which are basic elements of hydrocarbon migration in Liaodong Bay,form three kinds of transferring systems by mating.The oil reservoirs whose hydrocarbon migrated vertically along the faults often have multiple oil beds over lapped near the faults，and the faults are dominated by syndepositional characteristic.The oil reservoirs whose hydrocarbon migrates mainly along the connected sand bodies and faults mainly take shape in the highly porous and high permeable beds nearby the sides of faults， the key factors affecting transfering capability are special distribution and mating of faults and sand bodies.Hydrocarbon through the unconformity belts and sand bodies can migrate in a long distance and forms stratigraphic reservoirs，affecting transferring capability are porosity and lateral connectedness.The oilgas transferring systems determine types and distribution of reservoirs.In the north of Liaodong Bay,unconformities are common，which are favorable location for lithologic hydrocarbon reservoirs.In the middlesouth of Liaodong Bay，faults and sand bodes are abundance in number，which are favorable location for of structural hydrocarbon reservoirs.
