LEDOC-LET HT cement slurry system is the high temperature system of DOC-LET cement slurry system, it is composed of artificial glass beads DOC-P62 as weight lightening agent, DOC-BT1 and DOC-BT4 as enhancer and other materials as auxiliary agents. It is mainly used in long period cementing of high temperature deep well and cementing in lost circulation formation.
System Advantages
1、Strong temperature resistance and can be used in high temperature well.
2、High pressure resistance and small density change under high pressure.
3、Good sedimentary stability.
4、Cement stone is compact and with low permeability.
5、Good anti-channeling ability .
6、Strong corrosion resistance.
7、Cement stone possesses high strength and good lost circulation control ability.
System Features
1、Density : 1.5~1.7 g/cm3.
2、Temperature: 110~180℃.
3、Low fluid loss.
4、Almost right angle thickening.
