摘　　要：中原油田采油三厂 1 987年开始调剖 ,先后经历了纸浆废液、石灰泥、水泥浆单液调剖到钠土 +聚丙烯酰胺、盐酸 +水玻璃等双液调剖 ,其费用、投入材料的价值逐渐提高 ,多次重复调剖后增油量逐渐下降 ,吸水剖面并未得到明显改善 ,针对以上情况 ,我们合理优选调堵剂 ,加强油气层保护 ,降低调剖施工对油气层的伤害 ,改善吸水剖面 ,从而达到调剖增油的目的。Profile control has been applied in the No.3 Recovery Plant of Zhongyan Oil Field since 1987,which was experienced from single agent , paper slurry exhausted liquid ,lime slurry , cement slurry to double agents , bentonite and PAM , hydrochloric acid and water glass . The cost becomes more and more high and the production increment obtained by stimulation of profile control becomes more and more lower , at the same time ,the input profile are not improved distinctly . Aimed at these facts , the method of op...
