摘要:

针对意大利南亚平宁地区复杂逆冲构造使地震成像质量差、圈闭落实难度大、油气成藏特征不清楚的问题,
开展了构造对油气成藏要素的控制作用研究。研究认为,构造演化控制着优质烃源岩的展布;稳定的构造环境对烃源
岩发育起建设作用;剧烈的构造运动起一定的抑制作用;构造带控制储层、圈闭类型以及成藏组合的分布样式。逆冲

砂岩和中新统碳酸盐岩为主,前隆带主力储层则为中新统白垩系碳酸盐岩。构造古地理控制油气系统的分布。中
生代裂陷拉张阶段,古隆拗分布格局控制了油和伴生气系统。新生代碰撞阶段,前渊带的快速沉降控制了热成因气系

Abstract:

The complex structural condition in the Southern Apennine region of Italy results in poor seismic imaging quality,
great difficulty in defining traps,and unclear character of petroleum entrapment. We believe that the structural evolution controls
the distribution of high quality source rocks. The stable structural environment plays a constructive role in the development of
source rocks. The intense structural evolution plays an inhibition role in the distribution and development of source rocks. The
structural belt controls the type of reservoirs,traps and the distribution pattern. The primary reservoir in the thrust fold belt
is Cretaceous carbonatite;the primary reservoir in the internal foredeep belt is turbidite sandstones of Pliocene–Pleistocene;
the primary reservoir in the external foredeep belt is Pliocene turbidite sandstones and Miocene carbonatite,and the primary
reservoir in the forebulge belt is Miocene–Cretaceous carbonatite. The structural paleogeography controls the distribution of
petroleum systems. During the syn-rift stage in Mesozoic,the distribution pattern of paleo-uplift and depression controlled the
oil and associated gas. During the collision stage in Cenozoic,the rapid subsidence of foredeep belt controlled the thermorgenic
gas system. The biogas system migrated outward gradually along with the migration of depocenter in foreland basin during
Quaternary.

Key words: structural belt, petroleum entrapment elements, structural paleogeography, foreland Bbasin, southern Apennine
region
