摘要

运用成藏动力学系统理论和方法, 根据德南洼陷下第三系沉积、构造及异常压力等特征, 重点剖析了泥岩层的欠压实特点, 将其划分为3 个成藏动力学系统即下部高压它源封闭成藏动力学系统、中部高压自源封闭成藏动力学系统和上部常压它源半封闭成藏动力学系统。同时分析了本区以泥灰岩裂缝、砂岩、不整合面以及断层等组成的流体输导体系,并初步探讨了该区有利的油气成藏模式, 即陡坡带成藏模式、洼中垒成藏模式和缓坡带成藏模式。

Abstract

With the theory and method of the dynamic systemfor pool-forming ,

Denan depression has been classified into three kinds of

dynamic systems and four kinds of link systems , based on the

analysis of the sediment , structure , uncompaction and abnormal

pressure. The dynamic system for pool-forming of Eogene is

divided into lower part high pressure else-sourced closed dynamic

system, middle part high pressure self-sourced closed dynamic

system, upper part normal pressure else2sourced semi-closed

dynamic system. And the liquid link systems consist of marl

fissure , sandstone , unconformity surface and fault. Finally , the

favorable pool2forming models including actic region model , horst

model and ramp region model are discussed and the former two

kinds are principal.
