G202 Early Strength Additive for Oil Well Cementing
description1
Product Description
G202 can change ion concentration to accelerate dissolving of the components while cement hydrating, to speed acting ofC3A and forming of calcium aluminous stone, therefore it can densify the structure of cement and enhance the early strengthening.
Characteristics
Suitable for oil/gas wells whose temperature is between 28℃~200℃ (BHCT).
Modified from inorganic early-strength materials.
Normal dosage: 0.8%~1.5% (BWOC), and it is not confined in a particular case.
No chlorine ion, so it will not corrode the casing.
Increases early strengthening of cement effectively and has no harmful influence on increasing the strengthening.
Slight expanding effects can compensate the volume contraction of cement and can thereby improve the cementing quality of cement sheath.
Suitable for normal and low density cement slurry.
It can be used in shallow or middle-deep wells.
It can be mixed without water or with water.
Technical Specification
The ingredients of cement slurry in the table are: JiaHua G class cement, W/C: 0.44; Water quality: distilled water; Dosage of G202:1.5% (BWOC).
