Abstract

Multilayer heterogeneous sandstone oilfield in high water cut stage, the longitudinal upper sand body heterogeneity, each layer there is a big difference to use, the interlayer interference law is not clear. The research on subdivision water injection for different types of reservoir boundaries. In different high and low permeability core combination of series and parallel experiments, clarified the EOR effect to improve the core combination of different subdivision water injection. Application of grey correlation method, the main factors affecting the breakdown of water to control. Through the pilot test statistics X, Y reservoir, define reasonable subdivision water injection adjustment limit, guide the injection wells scheme can better segment measuring and adjusting control work, high water horizon invalid circulation, strengthen the use of low water flooding zones, alleviate the contradiction between layers.
