| 摘 要： | 珠江口盆地珠一坳陷在中始新世裂陷期文昌组沉积早、晚期之间存在明显的构造转换,该构造事件对古近系源-汇体系的形成和演变有重大影响。基于研究区地震、钻井、测井等资料的综合分析,本文认为构造转换控制了裂陷期源-汇体系的盆山地貌、物源供给、搬运方向及沉积样式等基本要素,并影响深层古近系储层条件。而且在构造转换的制约下,研究区发育物源迁移型和断裂转换型两种源-汇模式,前者的主物源在构造转换影响下发生变化,沉积边界、可容空间及沉积样式也随之改变,形成叠合连片的有利储集区;后者物源供给、搬运、堆积等在时空上发生有序变化,形成扇-洲-滩共存的复合沉积体系,储层条件分带性较强。因此,探讨构造转换控制下的源-汇体系特征及控砂模式,对寻找古近系优质储层有重要经济价值。

| Abstract: | An obvious structural transformation between the early and the late stages of the middle Eocene rifting in the ZhuⅠDepression,which has a significant impact on the formation and evolution of the Paleogene source-to-sink system,has recently been found.Based on comprehensive analysis of seismic,drilling and logging data in the study area,we argue that the structural transformation controls the basic elements of source-to-sink system,such as basin landscape,material source supply,transportation direction and sedimentary style,and affects the deep Paleogene reservoir conditions.Under the restriction of structural transformation,there are two typical source-to-sink models:source migration and fault transformation.Hydrocarbon accumulation related to structural transformation is commonly interpreted by two typical source-to sink models:source migration and fault transformation.The main source of the source migration model migrates under the influence of structural transformation,and the sedimentary boundary,accommodation space and depositional style change accordingly,forming a favorable superimposed and contiguous reservoir target;the supply,transportation and accumulation of provenance in the fault transformation model change orderly in time and space,forming the compound of co-existing fan-delta-beach sedimentary system and reservoir conditions have strong zonation.It is of great significance to explore the characteristics of source to sink system and sand-controlling model under the control of structural transformation in order to find high-quality reservoirs in Paleogene. |
