摘要
根据国内外不同有效厚度、不同开发阶段蒸汽吞吐引效的成功实例 ,推断出轻质油油藏蒸汽吞吐引效能够扩大油藏供液半径 ,提高油藏开发效果。该文对轻质油油藏注蒸汽吞吐引效机理进行了分析 ,对比了不同原油增产措施所消耗的费用 ,探讨了轻质油油藏注蒸汽吞吐引效的可行性 ,并结合油田挖潜的需要 ,提出了对套管进行热力保护或预引力完井的要求。采用该项技术将提高浅层轻质 (稀油 )油藏的开发效果。
It is inferred that the effect of steam stimulation in light crude reservoirs ca n enlarge the fluid supply radius and improve the development effect of such res ervoirs according to the successful cases for different effective thickness at d ifferent development phases both at home and abroad. In this paper, the mechanis m of the effect of the steam stimulation in the reservoirs is analyzed, the feasi bility of the effect discussed through the comparison among the costs consumed b y various crude oil stimulations and the claim of thermal protection to casing or well completion by pre-gravitations raised, combined with the need of tapping the potential in the oilfield. Adopting this technique, the development effect of the shallow light crude reservoirs will be improved.
