摘要
针对树脂类凝胶堵剂易受温度和盐度限制的缺点,本文研制出一种耐盐耐高温的改性聚丙烯酰胺凝胶堵剂(YN-1),是由改性聚丙烯酰胺与矿化度为10g/L的水配置而成的凝胶体。该堵剂具有较好的耐盐性能和耐温性能,不受地层渗透率的影响,同时还具有较强的耐冲刷性和封堵性,可满足某些高温高盐油田的堵水需要。
To solve the problem of many resin gel blocking agents are limited in the use of temperature and salinity,a modified polyacrylamide gel blocking agent(YN-1) with salt-tolerant and heat-resistant was prepared.It is compose of the modified polyacrylamide and salinity 10 g/L of water.The blocking agent is of better salt tolerance and heat resistance,without the impact of formation permeability.It also has a strong resistance to erosion and sealing.
