蒸汽驱开发是改善稠油油藏开发效果,提高原油采收率的有效手段。采用蒸汽驱开采使蒸汽冷凝前缘遗留的残余油饱和度,在蒸汽波及范围内降到很低,从而提高了驱油效率,达到提高采收率的目的。本文分析研究了锦45块于Ⅰ组油层吞吐中后期地下油藏的地质特征,应用筛选标准进行转驱方式筛选,并通过物模数模等手段分析研究,明确锦45块于Ⅰ组油层蒸汽吞吐中后期进行蒸汽驱试验的可行性。
Steam drive development is an effective means to improve the development effect of heavy oil reservoirs and enhance the recovery rate of crude oil. The residual oil saturation left by the steam condensing leading edge by steam flooding is reduced to a very low level within the range of the steam sweep, thereby improving the flooding efficiency and achieving the purpose of enhancing oil recovery. In this paper, the geologic characteristics of Jin 45 block in the middle and late period of reservoir stimulation in Block Ⅰ are analyzed and the screening methods are used to select the mode of rewinding. Through the analysis and study of the mode of module, Feasibility of steam flooding test in the middle and late period of throughput.
