【摘要】 介绍一种新的油井水泥复合早强剂—NSC,列举了NSC水泥浆各种性能的实验数据,描述了分别用NSC和CaCl₂水泥浆滤液浸泡人造岩芯的实验情况及数据分析,它的早强效果优于CaCl₂,特别是用NSC和CaCl₂处理的水泥浆滤液浸泡人造岩芯做渗透率测试的结果表明,NSC对储层损害小于CaCl₂ 还对NSC的促凝早强机理及水泥浆滤液对地层的损害机理作了初步探讨。更多还原

【Abstract】 We introduce a new kind of cement compounded accelerator-NSC, list variousproperties’ experimental data for NSC cement slurry and describe the experimental con-ditions and data analysis using both NSC and CaCl₂ filter liquor of cement slurry for arti-ficial rock core. NSC’s accelerated effect is better than CaCl₂’s. Especially the experi-ment above shows NSC’s harm is less than CaCl₂’s to reservoir. We also make furtherstudy for NSC’s accelerated principle and harm principle of filter liquor of cement slurryto the earth layer.更多还原
