摘　　要：为解决塔河油田碳酸盐缝洞型油藏在水驱开发过程中,因储层的非均质性较强,高渗透裂缝通道易发生水窜,整体水驱采收率偏低的问题,通过水驱流道调整,以颗粒药剂体系对水窜通道进行封堵调整,可以提高油藏采收率。通过深化油藏认识,形成缩缝分流、卡缝转向两种调流思路。同时,丰富调流药剂,主要包含复合颗粒体系和高黏液体系,形成一套针对塔河油田缝洞型油藏流道调整技术体系,在现场取得较好应用效果。The reservoir space of carbonate fracture-vug reservoirs in Tahe oilfield is featured with dissolved pores,caves and fractures.In the process of water flood development,high-permeability fracture channels are prone to water channeling because of the strong heterogeneity of the reservoir,so the overall water flood recovery rate is relatively low.Through the adjustment of water drive flow channel,the oil recovery can be improved by the plugging adjustment of water channeling channel with the application of granular medicament system.By deepening the understanding of the reservoir,two types of flow adjustment ideas are formed,namely shrinkage diversion and seizure steering.Meanwhile,the flow control agent is enriched,including the composite particle system and the high viscosity liquid system.A set of technical system is formed to adjust the flow channel of fracture-cavity reservoir in Tahe oilfield,and has gained good application effect on site.
