Prospects of exploring palaeozoic primary oil and gas pools in southern area of north china cratonic basin 华北古生代克拉通盆地南部原生油气藏勘探前景
3.
The analysis of primary oil distribution shows the base - level controlled oil distribution in reservoir . in this paper , subjects as following are discussed in detail 而构成储层的则主要是沟道、沟道间和席状砂体。
4.
The causes are discussed from aspects of oil - gas source beds , trapping and storing space , oil - gas migration channel and thick proofing layers , oil - gas maturity stage and allocation of effective trapping stage , suggesting the searching of primary oil - gas pool of the cambrian and lower ordovician at the relatively shallow layers and surrounding places with faults developed 从油气源层、圈闭与储集空间、油气运移通道与巨厚隔层、油气成熟期与圈闭有效期配置等四个方面探讨了未获油气之原因，提示在满加尔坳陷腹地，相对较浅部位及周边断裂发育部位寻找寒武系和下奥陶统的原生油气藏。
