Annotation:
Tests of grouting compositions for well conditions are carried out in accordance with ISO 10426-2 "Oil and gas industry. Cements and materials for well cementing. Part 2. Testing of well cements". Analysis of the effect of shear stresses on the parameters of cement slurries showed that slurries prepared in accordance with ISO 10426-2 are characterized by complete deflocculation of the suspension. On the contrary, shear stresses during well cementing do not always ensure complete deflocculation of the suspension. Therefore, when selecting formulations for grouting compositions, this can lead, for example, to the introduction of an incorrect amount of a set retarder.
