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...
