Abstract

AbstractIn view of the development characteristics of the tertiary oil recovery wells near the injection well row of the basic well pattern, such as low proportion of effective wells, low water cut reduction and low cumulative oil production per unit thickness, this paper makes an in-depth analysis on the potential and distribution characteristics of remaining oil near the injection well row of basic well pattern in depth. The effective characteristics, influencing factors and potential tapping technology of tertiary oil recovery wells near water injection well row in basic well pattern are also studied. It will have important guiding significance for the well pattern arrangement and potentiality exploration adjustment near the injection well row of the basic well pattern in the subsequent tertiary oil recovery block.KeywordsNear the injection well rowTertiary recoverWell pattern and well wpacing
