摘要
分析了塔河油田深井盐膏层的固井难点,优选出了高温抗盐降滤失剂RD221,分散剂DZS和缓凝剂RD441,评价了加入这些添加剂所形成的高温抗盐水泥浆体系的性能。室内试验和现场应用表明高温抗盐水泥浆体系能满足塔河油田深井盐膏层的固井要求。
The paper discusses the difficulties of cementing in deep salt-gypsum beds, optimizes additives (filtrate reducer RD221, dispersant DZS and retarder RD411), evaluates properties of cement slurries added with such additives under high temperature and salt conditions. Lab tests and field applications show that the cement slurry systems can meet demands for deep salt-gypsum beds cementing in Tahe Oilfield.
