ZOC-LET GR is the basic system of ZOC-LET system. It is composed of natural glass beads ZOC-P61 as weight lighting agent, ZOC-BT1/ZOC-BT4 as enhancer and other additives as auxiliary materials. ZOC-LET GR is suitable for cementing operation of low-pressure leakage well, long sealing section and under-balance drilling.
System Advantages
1、High early compressive strength, can be comparable with general density cement slurry
2、Good settlement stability of cement slurry.
3、Strong toughness and low permeability of cement paste.
4、Have a certain ability of anti-channeling.
5、Has a strong ability to resist corrosion
6、Has a good performance of lost circulation prevention.
7、Slurry can be mixed by sea water.
Basic Performance
1、Density range: 1.3~1.7g/cm3.
2、Applicable temperature: 27℃~110℃.
3、Low fluid loss.
4、Low free water.
5、Excellent comprehensive performance of cement slurry，thickening time can be adjusted.
6、System can tolerate a pressure of 30 MPa.
