摘要: 热力采油技术在水驱油藏中的应用已引起国内外专家的兴趣。为确定水驱后油藏适宜转注蒸汽的油藏条件,应用油藏数值模拟方法,研究了水驱后剩余油饱和度、油层厚度、净总厚度比、油层的非均质性、原油粘度等主要油藏参数对水驱后油藏转注蒸汽开发效果的影响规律,给出了水驱油藏适宜注蒸汽开发的油藏条件。水驱后的剩余油饱和度是影响水驱油藏能否转注蒸汽开发的主要因素,当剩余油饱和度不小于0. 4时,水驱后油藏可转注蒸汽开发。应用该油藏条件可对水驱后油藏能否转注蒸汽开发作粗筛选。

Abstract: The application ofThermal oilRecovery in reservoirs after waterflooding made the experts interesting at domestic and abroad. To determine the suitable reservoir conditions for steam injection, the effect of remaining oil saturation, formation thickness, heterogeneity and oilviscosity on the performance of steam injection inwater flooded reservoirwas studiedwith the reservoir
numerical simulation, and suitable reservoir conditionswere given in this paper. Remaining oil saturation afterwaterfloodingwas themain factor affectingwhether the waterflooding reservoir can be converted into steam injection. When the remaining oil saturation was not less than 0. 4, the waterflooding reservoir can be changed into steam injection. Using these reservoir conditions could basically be screened out the suitable reservoir afterwaterflooding converted into steam injection.

Key words: waterflooding reservoir, steam injection, thermal recovery, feasibility
