【摘要】 利用高精度三维地震资料解释成果,分析了济阳坳陷南部中、新生代不同构造运动期与多位态主断裂(系)相伴生的横向变换带特征。研究表明,印支运动期横向变换带为NNE向展布,由侧向挤压褶皱和侧断坡组成;燕山运动期横向变换带走向为NEE向,由传递断层和横向凸起构成;而喜马拉雅运动期横向变换带则表现为NW向,由走向斜坡和传递断层组成。横向变换带构造演化使其不同构造部位具有叠加与迁移演化的差异性变化,从而形成不同的构造背景,造成了油气的差异聚集,其中变换带叠加可形成复式油气聚集带,变换带迁移则造成"满洼含油"的油气分布格局。更多还原

【Abstract】 Using interpretation results of high-precision three-dimensional seismic data,the lateral transitional zone associated with faults of different occurrence are analyzed,which are from different tectonic movements since the Mesozoic in southern Jiyang Depression,Bohai Bay Basin.Research shows that the lateral transitional zone in NNE direction is composed of lateral compressive fold and lateral fault ramp in Indosinian movement.In Yanshanian movement,the lateral transitional zone is in NEE direction,which is assembled by the transfer fault and lateral uplift.The lateral transitional zone is NW,which is made up of the relay ramps and transfer zone in Himalayan movement.The different tectonic parts of lateral transitional zone possess unequal changes in evolution of superposition and migration respectively,creating different tectonic settings,which causes different migration and accumulation of hydrocarbon.Superimposed transitional zone can form composite zones of hydrocarbon accumulations.Migrated transitional zone can result in "sag-wide oil-bearing" hydrocarbon distribution.更多还原
