摘要 为了加深对桩海地区馆陶组上段沉积相的认识,根据测井资料、地震剖面资料、等时地层切片资料等,通过古地貌及砂岩百分含量等值线图,分析馆陶组上段物源供应特征和沉积特征,对沉积相平面展布特征进行刻画,并对储层有利区进行预测。结果表明,研究区存在来自西南和东南两个方向的物源;馆陶组上段早期发育了三角洲相,三角洲平原不发育,三角洲前缘较发育,以水下分流河道、河口砂坝和支流间湾等微相为主;有利区位于发育河口砂坝和水下分流河道的中部和南部区域。 To deepen our understanding of the sedimentary facies of the upper section of the Guantao Formation in the Zhuanghe area,we analyzed the sediment supply characteristics and sedimentary features through contour maps of paleogeography and sandstone percentage based on well logging data,seismic profiles,and isochronous stratigraphic slice data.The spatial distribution characteristics of the sedimentary facies were also characterized,and favorable reservoir areas were predicted.The results show that there are two sources of sediment supply from the southwest and southeast in the study area.The early stage of the upper section of the Guantao Formation was dominated by deltaic facies,dominated by microfacies such as underwater distributary channels,estuary sand bars and tributary bays.The favorable reservoir areas are located in the central and southern parts of the developing estuary sand barriers and underwater distributary channels.
