东海平湖油气田平湖组沉积相研究
|
摘要
平湖油气田是东海陆架盆地投入开发最早的油气田,平湖组是其主要的产层之一。长期以来,由于对平湖组沉积相认识一直存在分歧,影响了对其油气分布规律的认识。综合古生物、地化、岩心、录井、地震等资料,分析认为平湖组的沉积相为受潮汐作用影响的辫状河三角洲相,发育的主要微相类型包括有水下分流河道、河口砂坝、水下天然堤、分流间湾微相。这为油田下一步勘探开发提供了有益的指导。
Pinghu oil and gas field is the first field which has been put into production in East China Sea Basin,and Pinghu Formation is one of the major production layers.For a long time,due to different opinions on sedimentary facies of Pinghu Formation,the understanding about the distribution regularity of oil and gas has been affected greatly.In this study,with paleontology data,geochemistry data,coring data,logging data and seismic data,sedimentary facies of Pinghu Formation have been analyzed thoroughly.Through comprehensive study,it is believed that sedimentary facies of Pinghu Formation is dominated by braid river-delta affected by tide.The sedimentary microfacies include mainly subaqueous distributary channel,subaqueous levee,subaqueous inter-distributary channel,the mouth bar.The study will provide useful guidance for the exploration and development of Pinghu oil and gas field.
