Abstract: Hutubihe reservoir(K]h26~Kph2) of Wellblock Lu-9 in Luliang oilfield of Junggar basin is an edge-water reservoircharacterized by low amplitude structure, complicated oil-water relationship and intensive heterogeneity. Applying numerical simulationmethod,integrated with results of detailed reservoir description and reservoir engineering study,this paper presents technicallimitations of rational development of Hutubihe reservoir and determines that waterflooding process and inverse 9-spot pattern shouldbe adopted with the cut-offs such as rational production rate of 2.9%, reasonable injection-withdrawal ratio of 0.8, sound pressurelevel of 9.0MPa. It is indicated that these numerical simulation results are helpful to Luliang oilfield for high effective development.
