Analysis of the dominant seepage in high water-cut reservoirs by oilfield dynamic analysis and optimization software
Geological Research Institute of The Fourth Oil Production Plant of Daqing Oilfield Company Limited, Heilongjiang, Daqing 163511, China
The advantages of seepage is in the middle and later periods of the oilfield development, long-term injection water flushing formed under the change of reservoir pore permeability structure, increase the reservoir heterogeneity of change, in order to weaken the advantage of seepage affects the development effect, this paper use of high water cut oilfield adjustment and optimization software, the dynamic analysis for modeling is used to identify the advantages of seepage of the R D oilfield blocks. The static parameters and dynamic parameters are analyzed respectively, and different discriminant indexes are used to calculate water injection well and production well. The determination index of dominant seepage layer is determined for small layer in development block. The probability classification statistics and comprehensive score of daily water injection volume of water injection well are carried out to find the well layer with dominant seepage development, which is also a research direction of fine geological research.
Key words: Dominant seepage / Probability statistics / Discriminant index / Discriminant index of dominant seepage layer
