摘要： 针对高温高盐的严重非均质油藏,提出了交联—预交联复合调驱的技术设想,以进-步挖掘开发中后期高含水油藏的剩余油潜力，交联-预交联复合调驱结合了两种调驱剂不同的驱油机理，以实现驱替过程中的调堵协同作用。为验证技术可行性,复合调驱技术首先在文25东块实施,试验共选择了9个井组,实施完成7个井组,共注各种调驱剂7.922 6x10 m',总体效果实现了注入压力升高、改善波及体积的目的,试验累积增油8305t,是单纯预交联调驱增油效果的13倍。

Abstract: In light of reservoirs with high temperature, high salinity and high heterogeneity, this paper proposed the techrique of using crosslinked polymer and pre crosslinked gel agent for complex displacement to further exploit remaining oil potential during high water-cut stage. These two profile control agents are of diferent oil displacement mechanisms and act as coordination of fooding and plugging.In order to testify the validity of the technique, field tests have been made in selected 9 well groups in Wenliu-25 east block, of which 7 have been fufilled, injecting agents of 7.922 6x10* m' in total. The results show higher injection pressure and improved sweep eficiency.The amount of cumulatively increased oil reaches 8305t, corresponding to 13 times that of simply using pre-crosslinked agent in effctiveness.
