CASING HEAD ОКК1, ОКК2

The casing head OKK are intended for binding of two or more columns and check of pressure in inter-column space. Column bindings are produced at operating pressure of 21 and 35 MPa. Depending on the structure of downhole environment, bindings are produced as the following: Usual - for media containing petroleum, gas, gas-condensate, flush fluid, cement slurry, particles of bored soil, water and their mixtures. Corrosion-resistant (K2 and K2i)- for media containing oil, gas, gas-condesate, flush fluid, cement slurry, particles of bored soil, water and their mixtures containing H2O and C2O up to 6 % in volume.
