Application of proportion pluming in fractured and vuy reservoirs,Tahe Oil Field

Water was found at the bottom of the Ordovician carbonate fractured and vuggy reservoirs.The bottom water migrated along fractures into wellbore,resulting in well water.Water content rapidlyincreased,and pressure system and reservoir generation model varied between different wells,hencethere was no regularity for water plugging in carbonate rocks.A new proportion plugging technologywas developed and applied in carbonate reservoirs of the Tahe Oil Field,providing new ideas for watercontrolling and plugging in the study area.
