传递构造带对油气分布的控制作用分析

Analysis of control effects of transfer zone on petroleum and gas distribution

传递构造带对沉积作用的影响是通过控制地表水系来间接实现的,具有不同几何形态的不同类型的传递构造带,表现出对地表水流域的不同控制作用.这些受传递构造带控制的水系往往在传递构造带的凹陷内汇集并影响冲积扇-扇三角洲-浊积扇等扇状砂体的发育.这些扇状砂体由于靠近凹陷内部的生油岩系,或受传递断层的持续作用将其与生油岩系连通,而成为油气储集的有利场所,最终,在传递构造带内同时期形成的各种圈闭中聚集成,所以,传递构造带常常是油气的富集带.

The influence of transfer zone to sedimentation is indirectly achieved through controling the surface rivers.But the control effect of transfer zone on the surface rivers may be different for different geometry configuration.These surface rivers which are controlled by transform zone usually bind in the depression of transfer zone and affect the growth of alluvial fan,fan-delta and turbidite fan.These dene fans often become the profitable field of reservoir of petroleum and gas because they are adjacent to the oil-forming rock formation and connected with oil-forming rock formation by late transform fault.As a consequence,they are getting together in the various traps who formed in the same period in the transfer zone.Thus,transfer zone usually is the abundance zone of petroleum and gas.
