НЕФТЯНАЯ ПРОВИНЦИЯ

Abstract

​

The article presents the results of studies of expanding grouting material with a density of 1700 kg/m3, which allows cementing casing strings for the entire length with a single composition, without exceeding the pressure of hydraulic fracturing of weak layers, while ensuring a high rate of structure formation and strength gain, which in turn will significantly reduce the time of WOC. The solution from the proposed grouting material has: zero water separation, reduced fluid loss, and the stone has improved physical and mechanical properties, the presence of an expansion effect. The specified properties of the mortar and stone allow to increase the tightness of the casing annulus.

Key words:

​

well cementing, lightweight cement slurry; cement stone expansion; annulus integrity
