  ABSTRACT: Oilfield Q is a typical heavy oil reservoir, characterized by high porosity, high permeability, high crude oil viscosity, active edge and bottom water, and loose reservoirs that are prone to sand production. Since it was put into production in 2001, good development results have been achieved through comprehensive management measures such as optimized water flooding, infill well adjustment, separate-layer series development, and well pattern modification. It has now entered the late stage of development, showing characteristics such as rapid water cut rise, significant production decline, and low water flooding efficiency. Through the study of mechanism models, this paper screens out suitable blocks and optimizes the cyclic water injection parameters, achieving good results. It can provide a theoretical basis and reference for improving the development effect of heavy oil reservoirs in the ultra-high water cut stage.
