Abstract: The third member of Dongying Formation(E3d3) developed typical fan delta glutenite reservoirs in the northwestern margin of Bozhong Sag,however,the understanding of diagenetic evolution and controlling factors of the reservoirs are unclear. Based on the data of cores,wall cores,cast thin slice,scanning electron microscope, physical properties,combined with the burial history and hydrocarbon filling history,the diagenetic evolution and its influence on physical properties of fan delta glutenite reservoirs of E3d3 were studied. The results show that the reservoirs are macroscopically dominated by heterogeneously supported conglomerates,granular supporting conglomerates,conglomerate sandstones,medium-coarse sandstones,followed by fine sandstones; and are microscopically dominated by feldspar lithic sandstone and lithic feldspathic sandstone,with the lithic being mainly of volcanic rocks,followed by metamorphic rocks. The reservoirs have low permeability,and the reservoir space is composed of intergranular dissolved pores,followed by primary intergranular pores. The diagenetic environment underwent a change from neutral to acidic(meteoric water leaching),alkaline,acidic,alkaline,acidic to alkaline. Continuous compaction after meteoric water leaching and the cementation of carbonate and clay minerals under alkaline conditions are the fundamental reasons for the low permeability,whereas the meteoric water leaching and dissolution in acidic environments are the main reason for the formation of secondary pores,and the continuous hydrocarbon filling is conductive to the preservation of reservoir pores since 7 Ma. The alkaline fluid environment formed by organic acid decarboxylation since 1.5 Ma is easy to form carbonate cementation and illite filling,which is the ultimate cause for the formation of low permeability reservoirs.
