Title: Remained Oil Distribution and Its Potential Exploitation Technology in Wenliu Oilfield
Abstract: Remaining oil distribution in high water cut stage of Wenliu oilfield is studied using a number of data of production,log and testing.It points out the remaining oil is enriched in interlayer low-permeability section;formations with large difference between interlamination and poor physical property;the position of bad dynamic injection-production correlation in plane,lag area influenced by inter well percolating properties and macroscopic high position,low resistivity reservoirs are reinterpreted and discovered.The main methods of tapping the potential of remaining oil in old oilfield are discussed.It includes well pattern recombination,technology of target directional well,sidetracking,updating water injector,adjusting displacement by profile control of water injection wells,the horizontal well drilling technology,which have direct significance in field application.
