摘要
微细水泥可用作９０℃以上高温地层的堵剂。水泥浆凝结时间直接影响堵剂注入能力。本文报道水灰比（０．６—３．０）、温度（８０—１２０℃）及缓凝剂ＮＰ３加量对平均粒径５μｍ的微细水泥浆凝结时间影响的实验研究结果。
The influences of water to cement ratio (0.6—3.0), temperature (80—120℃) and retarder (NP 3) use level upon setting time of finely particulated cement (with particle size 5 μm in average) slurries as water shutoff/profile modification agent are investigated experimentally. The setting time temperature relationship of these slurries is that of Arrhenius type.
