Product details

Silica fume for shallow sea petroleum cementing can be added to concrete used for cementing shallow offshore oil wells to increase the life of the well. Microsilicon powder, also called silica ash for petroleum cementing or cohesive silicon ash, is ferroalloys in the smelting of ferrosilicon and industrial silicon (silicon metal), the mineral heat furnace produces a large number of volatile and strong SiO2 and Si gas, the gas is discharged with the air quickly oxidised condensation and precipitation. It is a by-product of large industrial smelting, and the whole process needs to be recovered with dust removal and environmental protection equipment, and because of the small density, it also needs to be encrypted with encryption equipment.
Microsilica powder is a new type of concrete admixture. The main component is si02, the average particle size of 0.1μm, 1% of the cement, the colour is light grey to carbon black, with volcanic ash reaction characteristics, can be hydrated to form a silica-rich gel, the strength is higher than the calcium hydroxide crystals, and the hydration of the cement gel C-S-H to work together, it is a very high activity of the water-hardened cementitious materials, mixed with it to make the concrete physical performance indexes improved substantially.

In recent years, micro-silica powder has also begun to be widely used in major oilfields. Especially in oilfield cementing, due to the use of microsilica powder, thus improving the mud curing body of high temperature resistance to strength decline performance. It is used in a large number of high temperature deep wells, geothermal wells and thermal recovery wells.
