Non-poisonous or non-odor.
It is compounded by foamer, foam stabilizer and fluid loss control additive.
Normal dosage: 0.3%～0.6% (BWOC).
Suitable temperature: 25～150℃.
It can produce little and well-distributed foam steadily, moreover, the foaming time is controllable.
No harmful on thickening time, rheological properies and free fluid control of cement slurry. Enhance compression strength obviously.
Suitable for cement slurry with normal and low density.
Particularly, it is suitable for boreholes which have irregular or enlarged hole diameter. It can also apply to well control and anti-migration in pressure balanced cementing of deep wells and adjusted wells, as well as cementing wells with high pressure and active oil and gas.
More ideal expanding result can be achieved by mixing it without water instead of mixing with water.
