摘要:
东海陆架盆地西湖凹陷北部渐新统花港组巨厚湿地扇砂体蕴藏着丰富的油气资源,其岩相属性关系到油气勘探中的储层认识。研究区北部G构造G-2井百米岩心所展示的丰富内容,揭示了花港组构造旋回底部湿地扇雏型期、建设期、消亡期的微相变化,以及不同微相碎屑粒度特征所反映的水力学行为。岩心所揭示的水道、坝滩沉积学特征差异,丰富了湿地扇沉积学特征、层序演化以及控相机制的内涵,为深层储层的分析与研究奠定了基础。
Abstract:
Thick humid fan sandbodies of Oligocene Huagang Formation are rich in oil and gas resources in the north of Xihu Sag,the East China Sea Shelf Basin.And their petrographic properties are related to the recognition of hydrocarbon reservoir exploration.The hundred-meter long cores,which were taken from G-2 well in G construct of the northern Xihu Sag,revealed the microfacies change from the humid fan embryonic period to the construction period,and then to the extinction period at the bottom of the Huagang Formation tectonic cycle,and the hydraulics behaviors reflected by grain-size characteristics of clastic rocks of different microfacies.The cores also revealed the sedimentary characteristics difference between channel and bar,which enriches the content of sedimentary characteristics,sequence evolution,and mechanism of controlling sedimentary facies,and then deepens the understanding of deep reservoirs.
