DOC-LET UL cement slurry system is the ultra low 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. DOC-LET UL system is mainly used in cementing under complicated geological conditions like high temperature and low pressure and easy-seeking and easy-lost.
System Advantages
1、High pressure resistance and small density change under high pressure.
2、Good sedimentary stability.
3、Cement stone is compact and with low permeability.
4、Good anti-channeling ability .
5、Strong corrosion resistance.
6、Cement stone possesses high strength and good lost circulation control ability.
System Features
1、Density : 0.9~1.3 g/cm3.
2、Temperature: 50~130℃.
3、Low fluid loss.
4、System can tolerate a pressure of 60MPa.
