Изобретение касается области бурения нефтяных и газовых скважин, в частности цементирования обсадных колонн. Целью изобретения является получение устойчивой прочности цементного камня и снижение стоимости проведения технологических операций. Поставленная цель достигается тем, что в тампонажный раствор, содержащий тампонажный портландцемент, пластификатор НТФ и воду, добавляется пыль-унос керамзитового производства при следующем соотношении компонентов, мас.%: тампонажный портландцемент - 52,6 - 55,5, пыль-унос керамзитового производства - 16,7 - 21,0, пластификатор НТФ - 0,02 - 0,022, вода 26,3 - 27,8.The invention relates to the field of drilling oil and gas wells, in particular cementing casing strings. The aim of the invention is to obtain a stable strength of cement stone and reduce the cost of technological operations. This goal is achieved by the fact that in the grouting cement containing grouting Portland cement, NTF plasticizer and water, dust-expanded clay dust is added in the following ratio of components, wt.%: Grouting Portland cement - 52.6 - 55.5, dust-fly-away claydite production - 16.7 - 21.0, plasticizer NTF - 0.02 - 0.022, water 26.3 - 27.8.
