大溫差專(zhuān)用緩凝劑 Special Retarder For Large Temperature Difference
簡(jiǎn)介Introduction
大溫差專(zhuān)用緩凝劑是一種專(zhuān)用于大溫差井固井的緩凝劑產(chǎn)品，適用溫度范圍廣，能實(shí)現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(diǎn)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(cháng)稠化時(shí)間，增加可泵時(shí)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.
