FIELD: oil and gas industry. ^ SUBSTANCE: suspension to be used in oil and gas wells, which contains the following components: aluminium silicate source, carrying fluid, activator of the group including metal silicate, metal aluminate, alkaline activator or their combinations. At that, suspension is capable of being pumped with the composition with such rheological properties that its viscosity is 300 CP or less, and suspension can be cured in well conditions. ^ EFFECT: obtaining geopolymer suspensions with possibility of monitoring the thickening and hardening periods of time for wide temperature intervals and density, which are capable of being pumped and used for well cementing. ^ 43 cl, 11 tbl, 4 ex |
