ABSTRACT:
Disclosed is a low-viscosity cement composition, useful in the field of oil drilling, comprising cement, water and an additive obtained by salifying into the alkali-metal, alkali-earth metal, or ammonium salt, the sulphonated and oxidated products derived from the reaction between sulphur trioxide and cookery tar or sulphur trioxide and fuel oil from steam cracking; the cement composition is endowed with improved rheological characteristics such as a low-viscosity value without substantial changes in the pumping times, even at high temperatures and pressures.
