摘要
针对胜利油区储层类型和油藏:河流相正韵律沉积、三角洲沉积及复杂断块油藏,开展了不稳定注水机理研究及现场先导试验并推广应用。实践证明不稳定注水能够提高注水波及系数,提高油藏最终采收率。该技术具有投资少、见效快、增油显著的特点,是一种深化二次采油、改善水驱油藏开发效果的有效技术手段。
In view of the heterogeneity and various types of reservoirs in Shengli oilfield(fluvial positive rhythm de-posit,delta deposit and complex fault block reservoirs),mechanism study,pilot and field application of unstable waterflooding were performed.Unstable waterflooding was verified to be able to enlarge sweep efficiency and en-hance the ultimate oil recovery.This technique has the outstanding advantages of small investment needed,rapid response speed and prominent increase of production and is an effective technological measure to deepen secondary recovery and improve development effects of waterflooding reservoirs.
