FIELD: chemistry.
SUBSTANCE: invention relates to a method for production of an aqueous cementing suspension, method for manufacture of an oil well structure, to an aqueous cementiting composition. This invention is based at least in part on the water-separated particles used as additives for the compositions. The particles are activated to regulate rheology when the water-soluble parts of the particles are released in the presence of water. The invention is developed in subclaims.
EFFECT: improved control of water loss, hydration, precipitation and separation of aqueous cementing compositions in wide temperature and time intervals.
