摘要
本文简要地介绍了含油气系统的内涵、研究内容和几个新概念，分析万安盆地的油气地质特征，认为该盆中发育了渐新统－中新统含油气系统（！），讨论了其生成子系统和油气运移－捕集子系统，最后指出油气勘探的有利地区。
The concept, investigation method and several terms of oil- & gas-bearng system are introduced in this paper. Based 'on the studied petroleum geology of Wan' an basin, the valu- able Oligocene-Miocene petroleum system in this basin may be divided into three petroleum subsystems, i.e.central-northern, southern and eastern Wan'an Basin subsystems. After comprehesively analysing the petroleum generating system and migration-entrapment system, the author pointing out finally the regions suitable for exploration in this basin are: the central- northern subsystem ranks fairly good whereas the southern and earstern subsystems be valued relatively poor.
