对于稠油油藏的开发,蒸汽驱能有效提升采收率。本文主要是从蒸汽驱的机理出发,探讨适合采用蒸汽驱的油藏条件。影响蒸汽驱效果的因素主要包括油层有效厚度、油层净总比、油藏埋深、含油饱和度、原油黏度和组分两个方面。选取某油藏进行效果分析,能获得较好的开发效果,可在稠油油藏开发中进行推广。
For the development of heavy oil reservoirs, steam flooding can effectively enhance oil recovery. Based on the mechanism of steam flooding, this paper discusses the conditions of reservoirs suitable for steam flooding. The factors affecting the steam flooding effect include the effective thickness of the oil layer, the net ratio of the oil layer, the depth of the oil reservoir, the oil saturation, the viscosity of the crude oil and the composition of the two aspects. Select a reservoir for effect analysis, can get better development results, can be developed in the heavy oil reservoir development.
