三叠系储层微裂缝发育，注水且具有明显的方向性，容易造成注入水沿微裂缝发育方向快速推进，而使油井水淹，采油三厂大部分三叠系油藏已经进入中高含水期，受储层微裂缝、高渗带、初期压裂规模较大、超前注水等综合因素影响，水淹井数呈逐年上升趋势，甚至迅速水淹，产能损失严重。针对这一生产矛盾，近年来采油三厂在充分调研各种堵剂体系的基础上，结合采油三厂低孔、低渗、微裂缝发育的油藏特征，研究剩余油分布规律，遵循“注的进、堵的住、安全性强”的原则，先后研发、引进智能弱凝胶、微纳米堵水凝胶、裂缝封堵剂等堵水材料进行油井堵水现场试验，并取得了较好效果，为后期油田高效开发提供了一定的借鉴。

Triassic reservoir micro crack development, water injection and has a clear direc- tion, easy to cause the injected water flow along the fracture direction of rapid advance, and make the water flooding, oil plant three most Triassic reservoir has entered into high water- cut stage, reservoir micro crack, high permeability zone, initial fracturing larger scale, ad- vanced water injection and other comprehensive factors effects of flooding well number, and a rising trend year by year, and even rapid flooding, severe loss of capacity. In view of this production contradiction, in recent years the three production plant in the full investigation of plugging agent system based on the combination of the three production plant, low porosi- ty, low permeability, fracture reservoir, deep study of residual oil distribution law, follow the ＂ injection inlet, blocking, and strong safety ＂ principle, has introduction of intelligent de- velopment, weak gel, micro nanometer blocking hydrogel, fracture sealing agent for water shutoff in oil well water shutoff material field test, obtained better result, later for efficient development of oil fields and provides reference.
