Fluid loss additives(OBC-G80S)

الوصف

OBC-G*0S 1.Summary OBC-G*0S is a kind of sulfonic fluid loss additive. It has characters like: anti high temperature, anti-salt, quick strength development, few free water. The product is appropriate to be used in different kinds of water and cement. It is also a kind of widespread use product, which can be used in different kinds of cement slurry systems.
OBC-G*0S is not only applicable in freshwater cement slurry , but also applicable in salt water cement slurry . 2.Functions It decreases the fluid loss obviously. In general, less than *0ml.If add the dosage, fluid loss will less than *0mL.
Effective salt resistance. It can be used in saturated salt water.
In the temperature of *0°C to *0°C,with the increase of temperature, the thickening time will increase too. It has no influence on muds strength.
Not sensitive to dosage, no catastrophe point, can be used in variable density cement slurry system. 3. Usage range Temperature: *0°C~**0°C(BHCT).
Recommended dosage: 0.6%*0.8% (w/c=0.*4).
Applicable in every kind of cement slurry systems, which are composed by every grade of oil-well cement (defined by GB****8 or APISpec*0A) and other additives (just like silicon powder, drift beads, fly ash, bentonite, barite powder and hematite.).
OBC-G*0S can be used together with medium temperature retarder (PC-H*1L),high temperature retarder (PC-H*1L), early strength agent (PC-A*0S) and disperser (PC-F*1L). 4. Technical data
