【摘要】 油气输导体系研究是油气藏成藏机理研究的重要内容之一。本次采取宏观和微观相结合的研究思路,综合应用录井、测井、地震、分析测试资料,识别江汉盆地江陵凹陷油气运移范围和路径,指出了油气运移的优势通道,分析了江陵凹陷输导体系的特征及其控藏作用。综合研究表明,江陵凹陷中的砂体和断层是油气运移优势通道,以连通砂体为主要运移通道的油气藏常形成于距烃源层较近或相邻的层位;而以断层为垂向运移通道的油气藏多在断层带附近多层叠置。更多还原

【Abstract】 Petroleum-conduct system is an important part of the reservoir mechanism research.Based on the data of drilling core,well-logging,seismic and analyzed testing,pathway and scope of hydrocarbon migration is identified,the perferential pathway is pointed out,the characteristic of conduct system and its control on hydrocarbon accumulation are analyzed in jiangling sag through macro and micro method.According to comprehensive research,sandbodies and faults are the main migration paths which construct petroleum-conduct system.The reservoir which takes sandbodies as the main paths always is formed near the horizon which is close to the source rock,and the reservoir which takes faults as the main paths always overlays near the faultzone.更多还原
