Abstract: In order to analyze distribution rule of remaining oil controlled by interlayer,the reservoir architecture and numerical simulation analysis of interlayer were carried out in Bohai A oilfield with high water cut stage. The results show that foreset imbricate interlayers are mainly composed of shale interlayer and tight sandstone interlayer,which average thickness is less than one meter. The remaining oil is controlled by position and area of interlayer. The longer the horizontal extension length of interlayer is,the greater the enrichment area of remaining oil is in the bottom zone of interlayer. In the injection well,oil well and interlayer configuration,when the production well penetrated into interlayer,interlayer has greater effect on remaining oil,which will be more enriched in bottom zone of the interlayer. Under the control of interlayer and reservoir rhythmicity,the remaining oil distribution patterns were divided into three types:interlayer top enrichment type,interlayer top-bottom enrichment type and interlayer bottom enrichment type. The results provide decision basis for adjustment,tapping potential and stabilizing oil and controlling water measures in late stage of oilfield.

Key words: tight oil reservoirs, dissolved pores, formation mechanism, Lucaogou Formation, Jimsar Sag
