Cementing Expansion Agent

Dr.Nzyme® Cementing Expansion Agent can form slight bubbles which distribute uniformly in cement slurry to compensate pressure decrease which results from jellification weightlessness and hydrating volume contraction, and enhance cementing strength of cement. Therefore, it can prevent oil, gas and water from migrating efficiently.
●Appearance: small particles or power, non-poisonous and non-odor.
●It is compounded by foamer, foam stabilizer and fluid loss control additive.
●Normal dosage: 0.3%～0.6% (BWOC).
●The suitable temperature is 77℉～302℉.
●It can produce little and well-distributed foam steadily, moreover, the foaming time is controllable.
●Not harmful in respect of thickening time, rheological properties and free fluid control of cement slurry. Enhances compression strength effectively.
●Suitable for cement slurry with normal and low density.
●Particularly suitable for boreholes which have irregular or enlarged hole diameter. It can also be applied for 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 streams.
●Better expanding results can be achieved by mixing it without water instead of mixing with water.
