Layers Subdivision and Waterflooding Timing in Low Permeability Offshore Reservoirs with Thin Interbedding
Conducted by the results of numerical simulation and reservoir engineering method, the limit of layers combination and the optimum starting time of water injection are present in this paper. It was shown that in order to improve the development effect of relatively low permeability formation and increase economic efficiency of this kind of field, the reasonable multiple factor after subdividing layers should be less than 5, which means that the permeability difference should be less than 8. Meanwhile, in view of the actual situations and difficulties of offshore development, the injection and production project should be started synchronously.
