L oilfield entered the stage of high water cut development, because the high water flooded zone in infill wells was not used in the early stage, the relationship between subsurface injection and production in some horizons was imperfect, and the remaining oil showed a distribution pattern of "overall dispersion and local relative enrichment", which affected the oilfield development effect. By filling holes in infill wells in time and perfecting the local injection-production relationship, the remaining oil in the imperfect injection-production parts can be effectively used and the oilfield development effect can be improved. In this paper, through the comprehensive analysis of previous hole-patching effects, the original well-selecting and layer-selecting standards are re-evaluated, the hole-patching and layer-selecting standards are further improved, and the oilfield hole-patching potential is implemented, which is of great significance for guiding the oilfield to tap the potential remaining oil.
