| 摘 要： | 以辽河油田某区块稠油油藏为例,通过数值模拟方法,系统研究了各种地质因素(地层倾角、渗透率、初始含油饱和度、油层厚度、油层深度和原油黏度)对水平井蒸汽吞吐转蒸汽驱的转驱时机以及对水平井蒸汽驱开发效果的影响。分析结果表明,影响较大的因素是初始含油饱和度、油层厚度以及原油黏度。该研究可为筛选稠油油藏水平井蒸汽驱开发的地质条件提供可靠的理论依据。

| Abstract: | The impacts of various geologic factors (stratigraphic dip, permeability, initial oil saturation, reservoir thickness, reservoir depth and crude oil viscosity) on the timing of converting to steam flooding after cyclic steam stimulation and the response of horizontal well steam flooding have been studied through numerical simulation for a heavy oil reservoir in Liaohe oilfield. The result indicates that the major influencing factors are initial oil saturation, reservoir thickness and oil viscosity. This stu... |
