摘　　要：介绍了一种应用于高温油藏调驱的新型调驱荆体系。该调驱体系由耐温聚合物、交联剂及矿物质PRT组成。重点描述了耐温调驱剂体系中耐温聚合物的合成、交联剂的优选及矿物质PRT对体系耐温性的影响，并对该耐温调驱荆的调驱性能进行了评价。评价结果表明，该体系在温度90—130℃、矿化度150000mg／L以下具有稳定的成胶性能，静态成胶时间在8—15h内可控，成胶强度大于35000mPa·s，对中高低渗及大孔道油藏均具有良好的堵塞性，在高温油藏调驱领域具有良好的应用前景。A new profile/displacement control system adequate to high temperature reservoir is introduced.It is composed of endure high temperature polymer,cross linking agent and PRT mineral mater.Synthesis of endure temperature polymer,optimize of cross linking agent and effect of PRT are also introduced.After evaluate of this system shows it has excellent gel capacity at condition of temperature below 130℃ and salinity below 150000mg/L,the time of static gel is controllable and the intensity of gel great than 35000 mPa·s.it has well block up ability for big narrow passage and all permeability reservoirs,and it has favorable application foreground in high temperature reservoir.
