大溫差專用緩凝劑 Special Retarder For Large Temperature Difference

簡介Introduction

大溫差專用緩凝劑是一種專用于大溫差井固井的緩凝劑產(chǎn)品，適用溫度范圍廣，能實現(xiàn)50~200℃溫差范圍全覆蓋。

The special retarder for large temperature difference is a kind of retarder product specially used for cementing in large temperature difference wells. It is suitable for a wide temperature range and can achieve a full coverage of 50 ~ 200℃temperature difference range.

性能及優(yōu)點Performance and advantages

l 在90℃-210℃（BHCT）井溫下使用效果較好；

l 在深井、超深井中使用，能有效延長稠化時間，增加可泵時間。

l It has good application effect at 90℃ ~ 210℃ ( BHCT ) well temperature;

l It can effectively prolong the thickening time and increase the pumpable time when used in deep and ultra-deep wells.
