摘要： 通过物理模拟和数值模拟,总结出“水平压裂”辅助蒸汽驱技术特点和增油机理,即利用水平裂缝控制蒸汽超覆速度、推迟蒸汽突破时间,有效提高了纵向波及系数。针对油藏特点,优化注汽参数,采用双裂缝、密集射孔、蒸汽压裂等技术,确保矿场试验在关键技术上获得了成功,使浅薄层超稠油蒸汽驱采油速度、累计油汽比和最终采收率分别达到了 17.4%、0.21 和 37.7%.

Abstract: By physical modeling and numerical simulation, the characters of horizontal fracturing-assisted steam flooding technology and oil incremental mechanism is summarized, that is, using horizontal fracture to control the steam overlaying rate and delay the steam breakthrough time can be effectively enhance the vertical sweep efficiency.According to characteristics of the reservoir, some new technologies and methods have been successfully applied in the pilot test, such as reasonable optimization of steam injection parameters, dual-fracture technology, dense perforation technology and steam fracturing technology.These critical technologies and methods allow the production rate, the cumulative oil-steam ratio and ultimate recovery factor of the shallow-thin and extra-heavy oil by steam flooding process to reach 17.4%, 0.21 and 37.7%, respectively.

Key words: Gucheng oilfield, extra-heavy oil, horizontal fracture, steam flooding, numerical simulation, physical modeling
