Water flooding timing is the research focus in the process of reservoir development, especially for offshore reservoir, reasonable water flooding timing can ensure better development effect, at the same time, it can save the investment cost in the process of reservoir development, so as to achieve sustainable and efficient development of offshore oilfield. At present, there are many researches on the flooding timing of conventional heavy oil reservoir, but few on the flooding timing of light oil reservoir. In order to clarify the development effect of light oil reservoir under different water flooding timing, taking offshore oilfield A as an example, combining with numerical simulation technology and reservoir engineering analysis method, the development effect under different water flooding timing is analyzed. The results show that when the reservoir pressure drops to half of the saturation pressure, the development effect of water flooding for light oil reservoir is the best. Therefore, the water flooding time can be postponed for the light oil reservoir with high porosity and permeability. The research results are applied to the actual development case of oilfield A. The practice shows that water flooding in the late development stage of light oil reservoir can effectively prolong the water-free oil production period, improve the initial oil recovery rate, reduce the initial development investment, thus effectively shorten the investment recovery period and improve the development effect of the reservoir in the whole life production cycle.
