摘　　要：流线模型作为一种新兴的工具被广泛应用于油田开发方案编制、效果评价与指标预测等方面。通过建立深部调剖流线模型,对比分析了注入调剖剂前后流线变化规律,提出了相应的渗流场变化模式。在流线模型的基础上,分析了调剖位置、调剖时机、封堵率、注入浓度对调剖效果的影响,进而引申出深部调剖矿场试验中的关键指标。结合某试验区实际井组评价了影响矿场试验效果的决定性因素,对同类区块开展深部调剖有一定的借鉴意义。The streamline model has been used to make oil field development program, to evaluate the effectiveness of adjustment and to forecast the indices of production as a burgeoning tool. We analyze the changing regularity of streamline before and after in-depth profile control agent injection, reveal the corresponding seepage field changing mode by building the deep profile-controlling streamline model. Based on the streamline model, the influence of position, timing, stemming ratio and the injection concentration on the effect of profile-controlling have been analyzed, and then the key indices of deep profile- controlling pilot site are proposed. The conclusive influence factors of the effectiveness of the test have been found from two well groups in WLW pilot site, which can be definitely used as reference for the application of deep profile control agent in similar oil fields.
