Study On Reasonable Development Index Of Water Flooding In Ultra-high Water Cut Stage In Lamadian Oilfield

Since ultra-high water cut stage,there are development differences in the well pattern of various water flooding layer systems.Changes are emerging for every development index.Research is urgently required to ensure sustainable water flooding exploitation without increased recoverable reserves.Therefore,this study proposes a framework for reasonable development Index of water flooding in ultra-high water cut stage,detailed research on geological characteristics of the study area,and identification of sedimentary characteristics.Through the use of multiple water flooding characteristic curve method,in combination with influence factor analysis of each development index,the reasonable development index is addressed,the exploiting effect of ultra-high water cut stage is evaluated,future water flooding and oil gathering scale and adjusting direction are identified,and thus a strong guidance is provided for the annual planning of water flooding in high water cut stage.
