DOC-SMART SL cement slurry system is composed of fluid loss additive DOC-G83L, retarder DOC-H21L、DOC-H100L、DOC-H42L、DOC-H50L and defoamers DOC-X60L、DOC-X63L. DOC-G83L used in this system is kind of salt water(sea water) fluid loss additive, it has strong salt resistance and is applied to cementing of seawater mixed slurry and ntermediate casing and tail pipe cementing on gypsum-salt bed.
System Advantages
1、Excellent salt resistance.
2、Can be mixed with seawater, high efficiency of construction.
3、Good mobility of cement slurry.
4、Strong fluid loss and free fluid control ability.
5、Well strength development of cement stone.
System Features
1、Slurry can be mixed with seawater.
2、Applying to gypsum-salt bed cementing.
3、Can be used under circumstance temperature ranges from -10 to 40℃.
4、Can be used in cementing construction both on offshore platform and in the land.
5、API fluid loss below 50ml.
