蒸汽驱是稠油油藏开采较为有效的技术，由于受诸多条件影响，为了较为全面地认识蒸汽驱这一开发方式，利用三维物模装置，以某油田稠油油藏为主要原型，通过蒸汽驱物理模拟方法研究注入压力、蒸汽干度、注汽速度等因素对稠油蒸汽驱的影响。通过研究发现注入压力大，采收率提高；当蒸汽干度大于50％，在蒸汽驱过程中，蒸汽干度越高，驱油效果就越明显。
蒸汽驅是稠油油藏開採較為有效的技術，由于受諸多條件影響，為瞭較為全麵地認識蒸汽驅這一開髮方式，利用三維物模裝置，以某油田稠油油藏為主要原型，通過蒸汽驅物理模擬方法研究註入壓力、蒸汽榦度、註汽速度等因素對稠油蒸汽驅的影響。通過研究髮現註入壓力大，採收率提高；噹蒸汽榦度大于50％，在蒸汽驅過程中，蒸汽榦度越高，驅油效果就越明顯。

Steam flooding is a relatively effective thermal technology for heavy oil reservoirs .The steam flooding is limited by many conditions .In order to understand the steam flooding development way more comprehensively , a three-dimensional model based on a certain oilfield is used in this paper to study the factors that influence heavy steam flooding , such as steam injection pressure , steam dryness , and steam injection rate , through the physical simulation methods of steam flooding .And it turns out that reservoir recovery efficiency can be increased with the increase of injection pressure; when the steam dryness is higher than 50%, the displacement efficiency will in-crease with the increase of steam dryness during the steam flooding .
