Abstract: Current situations and study achievements in polymer for heat tolerate and salt resistant flooding and flooding with surfactant have been summarized home. The performance of heat tolerate and salt resistant functions is often improved through the ways of copolymerizing monomer or controlling the structure of some special molecules in polymer flooding. Up to now, multicomponent copolymerization includes associating type, zwitterionic type, block structure, star structure, and crosslinked structure. A series of products have been applied which include

oxyneurine surfactant, anion and non-ionic ampholytics and Gemini surfactant by optimizing the raw materials and improving the molecular structure in surfactants oil driving. The performance and applied feasibility of different new type of chemical agents for oil driving are deeply analysized in this article, and the next goal for chemicals with heat tolerate and salt resistance flooding is pointed out.

Key words:

chemical flooding, polymer, surfactants, heat tolerate and salt resistance, molecular structure
