Passage systems can be classified into fracture type, sand body type, unconformity type, and compound type by composition; into effective passage system, and high-effective passage system by validity; and into passage system, and subtle passage system by identification.
输导体系按构成分为断裂型、砂体型、不整合面型和复合型;按有效性分为有效输导体系和高效输导体系;按识别难易程度分为输导体系和隐蔽输导体系。
Based on fault,sand body and matching relationship of sand-fault,geological,seismic and geochemical data were used to study the oil resource,effective migration pathways and pool-forming model of Xindong area in Dongying depression.
以断层、砂体及断-砂组合关系分析为基础,结合地质、地震、地化等资料,对东营凹陷辛东地区的油气来源、有效输导体系和成藏模式进行了研究。
To ascertain transmit faults is the key factor to confirm the effective migration pathways which are consist of fault,sand body,unconformity,etc.
以渤海湾盆地东营凹陷中央隆起带为例,从油气地化特征、流体性质、油气显示、原油物性等方面入手,总结了断陷盆地油气有效输导体系的判识方法,明确了有效输导体系的分布特征。
