| Abstract: | After 13 years' development,degree of oil recovery of Pinghu Oilfield has reached 41% and water cut is 96%.In view of complicated distribution of residual oil and no candidate reservoirs,some methods to improve oil recovery ratio was proposed in this paper including fine interbed analysis,geo-modelling,simulation,layer recombination,water shutoff,log re-interpretation for old well,well shut-in for deconing,etc.After using these methods on different oil wells,oil production rate increases in a period of time and production decline was slow down,and these methods can be used as reference for similar oil fields at extra high water cut period. |
| Keywords: | extra high water cut oil recovery interbed deconing |
