Deep-sea low-temperature and low-density oil well cement:
The deep sea water is of low temperature, high pressure, low formation fracture pressure, with commonly associated shallow flow and natural gas hydrate. In the past, the low-density foam cementing for deep sea cementing at a low temperature was adopted, which often involves with complicated construction processes, various changing factors and high cementing risk.
The deep-sea low-temperature and low-density oil well cement developed by our company mainly contributes to overcoming the deficiencies of slow strength development and high density of conventional oil well cement. At the temperature of 5 ℃, the strength can reach above 3.5MPa after 8 hours. Moreover, the slurry density is controlled within the range of 1.50±0.02g/cm3.
Main parameters:
