珠江口盆地白云凹陷构造演化与油气系统的关系
|
摘要
白云凹陷是珠江口盆地的一个次级凹陷,蕴藏着丰富的油气资源,是珠江口盆地重要的油气探区之一。白云凹陷形成和演化过程经历了3个阶段:断陷、拗陷和差异升降阶段。多期构造运动叠加造成凹陷内地质构造非常复杂。从白云凹陷构造演化和构造特征研究出发,结合地震剖面、测井资料,初步探讨了白云凹陷构造对油气藏形成的控制作用,明确了构造演化、构造样式对油气生运聚的作用和影响。认为新生代以来的构造活动对盆地最终构造格局形成产生了极为重要的影响,且对油气的运聚成藏及分布起到了决定性的控制作用。
The Baiyun Sag,as one of the important hydrocarbon accumulation zones in the Pearl River Mouth basin,is a secondary depression.The formation and evolution of the sag could be divided into three phases: the rifting phase,the depressive phase and the differentiated uplifting-subsiding phase.The structure of the Baiyun Sag is very complicated because of the stacking of multiple tectonic movements.Based upon the basin tectonic evolutionary history,combined with seismic profiles and well logs,we discussed in this paper the tectonic control over the hydrocarbon generation,migration and accumulation in the sag.Data suggest that the tectonic activities since the Cenozoic have rendered strong influence on the formation of the final structural framework of the sag,and played an important role in the accumulation and distribution of oil and gas.
