FIELD: construction.
SUBSTANCE: invention relates to the method for cementing a pipe or a shell in a gas well, which includes: (a) introducing into the wellbore cementing grout comprising water, cement and methylhydroxyethylcellulose (MHEC), wherein the MHEC amount is in the range of 0.05 to 1.50 percent by weight of cement, the grout density being in the range of 0.72 g/cm3 (6.0 ppg) to 1.74 g/cm3 (14.5 ppg), and (b) allowing the grout to solidify into a solid mass. Invention is developed in the dependent claims of the invention formula.
EFFECT: preventing slippage or migration of gas into the wellbore and improving the cementing grout stability.
