摘　　要：针对高温油藏层间层内矛盾、水驱开发效果差的问题,进行了深部复合调剖技术研究。通过物理模拟实验研究了复合调剖剂不同粒径、不同注入次序和注入强度下的调剖效果。结果表明:预交联水膨体颗粒+微球组合体系可使非均质地层采收率提高20%以上;高温可动凝胶+微球组合体系能启动低渗透层的原油,实现调剖和驱油的双重效果;高温可动凝胶按先弱后强的强度注入顺序可获得较高的波及体积和采收率。研究结果可为高温油藏控水增油提供一定的参考依据。The deep composite profile control technology of high-temperature reservoir is studied in order to solve the interlayer and inlayer contradiction of high-temperature reservoir and improve the poor water flooding result of high-temperature reservoir. The profile control results under the composite profile control agents of different grain-size,different injection order and different injection amount are studied by physical simulation experiments. The results show that the compound profile control system of pre-crosslinked swellable particles with microsphere can make the recovery factor of heterogeneous reservoir increase by more than 20%; the compound profile control system of high-temperature movable gel with microsphere can activate the crude oil in low permeability reservoirs,which realizes the dual effect of profile control and oil displacement; injecting high-temperature movable microsphere gel in the order of firstly strong and then weak injection intensity can enhance the swept volume and recovery factor. The deep composite profile control technology of high-temperature reservoir can provide technical support for the water controlling and oil increasing of high temperature reservoirs.
