摘要
综合地震、测井、岩心及试油等资料,对廊固凹陷古近系沙三中下亚段深水期大兴砾岩体的成因类型、孔渗特征及油气产能进行研究。在沉积背景分析的基础上,依据岩心、地震相和测井相,建立了断槽重力流、颗粒流型近岸水下扇和泥石流型近岸水下扇3种砾岩体成因模式。断槽重力流砾岩体主要由杂基支撑的砾岩和颗粒支撑的砾岩组成,砾岩中各类次生孔隙发育;颗粒流型近岸水下扇砾岩体主要由颗粒支撑的砾岩组成,储集空间以砾内溶孔、晶间孔和裂缝为主;泥石流型近岸水下扇砾岩体主要由杂基支撑的砾岩组成,孔隙类型主要为砾内溶孔。不同成因的砾岩体,其储集层特征和油气产能存在明显差异,其中颗粒流型近岸水下扇砾岩体储集层的孔渗条件最好,油气产能最高,是勘探的重要目标。
The genetic types,porosity and permeability characteristics,as well as oil-gas production capacity of the Daxing conglomerate bodies in the lower and middle sections of Paleogene Sha 3 Member,in the Langgu Sag of the Bohai Bay Basin are studied by combining various data such as seismic,logging,core analysis and formation testing.Three genetic models of conglomerate bodies including faulted-trough gravity flow,grain flow dominated nearshore subaqueous fans,and debris flow dominated nearshore subaqueous fans are built based on core,seismic and logging phases figured out by analyzing the sedimentary settings.The conglomerate bodies generated due to faulted-trough flow are mainly composed of matrix supported conglomerates and grain supported conglomerates,in which various kinds of secondary pores are developed;the conglomerate bodies generated in grain flow dominated nearshore subaqueous fans primarily consist of grain supported conglomerates,of which the reservoir space is mainly dissolved pores within gravels,intercrystal pores and fractures;the conglomerate bodies generated in debris flow dominated nearshore subaqueous fans are mainly composed of matrix supported conglomerates and are dominated by dissolved pores within gravels.The conglomerate bodies with different genesis have different reservoir characteristics and oil/gas production capacities.Among them,the conglomerate bodies generated in grain flow dominated nearshore subaqueous fans have the best porosity,permeability and the highest oil/gas production,thus are the key targets for petroleum exploration.
