ZOC-LET LT cement slurry system is the low temperature system of ZOC-LET cement slurry system, it is composed of artificial glass beads ZOC-P62 as weight lightening agent, ZOC-BT1 and ZOC-BT4 as enhancer and other low temperature materials as auxiliary agents. ZOC-LET LT system is mainly used in deepwater surface cementing and loosen and lost circulation formation cementing when the temperature is below 30℃.
1、High early compressive strength under low temperature.
2、Good sedimentary stability.
3、Cement stone is compact and with low permeability.
4、Strong anti-channeling ability which helps to prevent shallow flow.
5、Low hydration heat which helps prevent gas hydration.
6、Slurry an be mixed by both seawater and freshwater.
1、Density : 1.5~1.7 g/cm3.
3、Low fluid loss.
4、Strength can reach a 3.5 MPa under low temperature.
5、Materials influence slurry performance regularly.
6、System can tolerate a pressure of 60MPa.
