Abstract

Nowadays in the construction of underground structures (oil and gas wells), exclusive standards to the strength of the cement stone and water permeability are demanded. It is essential significantly when casing string cementing of oil and gas wells (for intermediate and casing strings) at Drilling Department «Ukrburgas», especially when closely spaced productive and water-bearing horizons with different anomaly coefficients are present. One of the ways to improve the requirements ofcasing string cementing is the use of different chemical additives in cement that change the structure of well cement. One of them is hydrophobic additive «Silpan-Р».
