摘要
通过对美国、独联体、西德和法国等国家在高温、高盐和低ＰＨ值的恶劣油藏条件下运用新型生物聚合物进行注水井调剖的现场实例分析，发现利用黄胞胶凝胶、新型生物聚合物Ｓｉｍｕｓａｎ／硅酸盐凝胶以及由产碱杆菌所产生的胞外聚糖ＡＧＢＰ新型生物聚合物进行调剖，效果好，成本低。
The field application cases of new biopolymers for water injection and profile control were analyzed in oil reservoirs with stern conditions as high temperature, high salinity and low pH value conducted in the United States, the commonwealth of Soviet Union, Western Germany and France. It is discovered that good results of profile control have been obtained cost effectively by xanthan/Cr +3 gelant solution, Simusan Silicate, and AGBP. Therefore, they are ideal agents for water control and profile control in high temperature oil reservoir with high salinity.
