在充分研究靖安油田大路沟二区和白于山区油井含水上升快（或裂缝水淹）原因的基础上，通过室内实验对“预交联颗粒+PL调剖剂+缔合聚合物+水驱流向改变剂”复合深部调剖体系的主要成分“水驱流向改变剂”和“缔合聚合物”在不同环境下的膨胀特性、稳定性以及剖面改善能力等性能进行了研究，并把复合深部调剖体系用于现场试验，结果表明该体系既可以有效封堵高渗通道，又可以使深部液流转向，同时具有见效快、有效期长、施工工艺简单、环境污染小等优点。该复合深部调剖体系解决了大路沟二区、白于山区油藏油井含水上升快（或水淹）、采收率低的问题，为今后治理大孔道或裂缝见水油藏提供了技术支撑。

On the basis of studying the reasons of oil wells′ water rise rapidly in the second area of Dalugou and Baiyushan area of Jing′an oilfield, the paper studies the expansion characteristics, stability, and profiles improve ability in different environment of the “Water Flowing Direction Changing Agent” and “Associated Polymer”, which are the main components of the “pre-cross linked particle + PL profile control agent + Associating Polymer + Water flooding the flow of change agent” profile control system. This profile control system is used in field experiments too. The application and evaluation show that the system can effectively block permeability path and make deep flow shifted. It also has characteristics of long valid period, simple construction process and little environmental pollution. The systems can solve the problems of the reservoirs′ well-water rise fast (or flooding) and low recovery in second area of Dalugou and Baiyushan area, and provide technical support for the management of large pores or cracks reservoirs which produce water.
