摘要
揭阳凹陷A区位于珠江口盆地东南部与台西南盆地西南部过渡区,属于中-新生代形成的断陷盆地。受制于缺乏基础资料(仅有二维地震),该研究区勘探工作一直未有进展。研究工作中充分利用新采集的三维地震资料,以层序地层学理论为指、结合构造分析与烃源岩压力预测技术,完成区内地层发育、洼陷结构特征、烃源发育以及构造目标、岩性目标发育情况总结,综合分析认为:研究区具备形成石油天然气的基本地质条件,勘探前景评价认为,研究区域具有可观的石油地质储量,是油气藏勘探的重要场所。
The area A of Jieyang Depression,as a Mesozoic and Cenozoic fault depression basin,is located in the transitional zone between the southeast Pear River Estuary Basin and the Southwest Taiwan Basin.Due to lack of basic data(only 2D seismic data is available),the progress of hydrocarbon exploration is lagged behind other regions.Based on newly acquired 3D seismic data,under the guidance of sequence stratigraphy,by using the new technology for seismic data interpretation and pressure prediction technology for hydrocarbon source rock evaluation,we made a comprehensive summarization in this paper on stratigraphy,tectonic framework,source rocks and exploration targets for further research.The results suggest that the depression has favorable conditions for hydrocarbon generation and accumulation.Further exploration is recommended and required.
