Abstract: the high angle tectonic fracture and bedding distribution of diagenetic fracture are developed in Anpeng deep layer extra-porous,extra-low permeability glutamate reservoir.Main structural fractures includes four groups as near east-westward,north eastward,north westward and south northward groups.The east-westward fracture is devel-oped better,then the north eastward,the north westward and south northward are worse.The influence of current ground stress to north eastward made the largest oneness in north eastward fracture,best connectivity,and highest per-meability,which are main permeable fracture of the area.The fracture development degree affected oil well production capacity,water content change and water absorption in water injection well.Developed well pattern does not match the fracture,which is currently the main reason for the poor effect.According to the characteristics of the development of fracture and its influence to the development,the current fivepoint well pattern of east westward well collocation can be converted to parallel north eastward to main permeable fracture row injection-production patterns,which have good development effect.
