This is a cement system that allows you to create a reliable barrier when cementing steam injection wells, where the temperature of the working agent exceeds 300 ° C. The unique composition allows it to withstand cyclic temperature loads, preventing cracking and, as a result, a leakageof the annulus.
Physical form: powder, gray to dark gray color
Water solubility: partial
PROPERTIES OF CEMENT STONE
Slurry density – from 1,8 g/cm3 to 2 g/cm3
Compression strength at 60°C after 48 hours is not less than 19 MPa
Thickening time – adjustable
PACKAGING AND STORAGE CONDITIONS
SteamJetCem is packed in soft containers weighing up to 1 ton, equipped with a triple polyethylene liner. The product should be stored in a dry place on pallets, away from moisture, open flames and heating appliances. After the bag has been opened, it must be carefully closed to avoid damage to the product.
The shelf life of the product is not less than 12 months.
SteamJetCem is a multi-component mixture of materials, predominantly of inorganic origin
The stone can maintain temperature differences in the radial and axial directions.
The absence of cracks in the cement stone, as a result, there is no heat loss during steam injection into the formation.
The trouble-free life of the well has been increased.
RESTRICTIONS CONCERNING THE USAGE
Operating temperature range: from 15°С to 400°С
