摘要：

针对塔河油田碳酸盐岩缝洞型油藏缝洞结构复杂导致开发中后期剩余油分布认识不清的问题,从油藏实际出发,在油藏精细描述、测试及生产动态资料分析的基础之上,提出了碳酸盐岩缝洞型油藏7大类13亚类剩余油分布模式。井点剩余油有3大类8亚类,即阁楼型、致密段遮挡型及底水上升封挡型;井间剩余油有4大类5亚类,即低幅残丘型、支流河道型、分隔缝洞型及高导流通道附近孔缝型。结合生产实践,针对不同剩余油分布模式提出了剩余油挖潜对策:对井距较大的井间未井控缝洞中各类剩余油,通过部署新井或利用老井侧钻进行挖潜;对于井距较小的各类剩余油则利用常规措施有针对性地进行挖潜;大型酸压、水力扩容和排水采油、注气替油分别是分隔缝洞型及阁楼型剩余油独具特色的有效挖潜措施。在塔河油田开发生产过程中针对各类剩余油分布模式的挖潜工作取得了较好增产效果,为同类油藏的剩余油挖潜提供了思路和方法借鉴。

Abstract:

The distribution of remaining oil in Tahe oilfield during the middle and later stages of development is not well understood, mainly due to highly complex fracture-cavity structure of carbonate reservoirs. This study starts from the practical situation of oil reservoirs and lays an emphasis on detailed reservoir description and testing and dynamic production data analysis. Seven types and thirteen sub-types of remaining oil distribution patterns are put forward. These include three types and eight sub-types of wellhole-adjacent remaining oil, i.e., attic type, screened dense layer type, and blocked type due to rise of bottom water. Additionally, there are four types and five sub-types of interwell remaining oil, i.e., low-amplitude monadnock type, branch channel type, separated fracture-cave type, and pore-fracture type near the high diversion channel. Combined with production practices, potential-tapping countermeasures are proposed for different remaining oil distribution patterns. On the one hand, drilling new wells or sidetracking from the existing wells are recommended for all kinds of remaining oil existing in non-well-controlled fractured-cave with relatively large well spacing. On the other hand, routine targeted potential-tapping measures are chosen for those with relatively small well spacing. Large-scale acid fracturing-hydraulic dilation and drainage process-displacing oil with gas are unique and effective measures for separated fracture-cave and attic patterns, respectively. Good results of increasing production have been gained by tapping the potential of all kinds of remaining oil during the development of Tahe oilfield. This study provides new thinking and reference measures for remaining oil digging in similar oil reservoirs.
