摘　　要：黄陵地区S区块长6油藏储层低孔低渗透,油水同层较多,无明显油水边界,开发初期油藏高含水期,产量低、递减快、油井含水上升快,导致油井稳产难度加大,因此,对该油藏进行开发动态分析十分必要。采用注水参数运行、注水方式、存水率变化、水驱效果等方面评价指标进行动态开发分析,发现该区块水井利用率低,注水强度小;注水方式采用超前温和注水;注采比较低,需要加强注水;存水率随着采出程度增大而增大,需加强注水;长6水驱控制平均值为24.74%。Chang 6 reservoir in S block in Huangling area has low porosity and low permeability,more oil-water layers and no obvious oil-water boundary.In the high water cut period of the reservoir at the initial stage of exploitation,the production is low,the decline is fast and the water cut of the oil well rises rapidly,which makes it more difficult to stabilize the production of the oil well.Therefore,it is necessary to conduct a dynamic analysis for the reservoir.In this paper,the dynamic analysis of water injection development effect is carried out in the aspects of water injection parameter operation evaluation,water injection mode evaluation,water storage rate change index and water drive effect evaluation.At present,the utilization rate of water wells in this block is low and the water injection intensity is small;The water injection mode adopts advanced mild water injection;Injection production is relatively low,and water injection needs to be strengthened;The water storage rate increases along with recovery degree,so it is necessary to strengthen water injection;The average control value of Chang 6 water drive is 24.74%.
