FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and gas production industry, namely to expanding oil wells, and can be used for cementing inter-column space in oil and gas wells, and also to the construction sphere for fastening elements of building structures, anchor bolts, decor elements. Composition of the plugging action contains a mixture of portland cement and cementing portland cement, quartz sand with grain size no more than 2.5 mm, pre-treated with a stream of accelerated electrons with an absorbed dose of 600 kGy, at the following components ratio, mass%: Portland cement 24–29, plugging Portland cement 3–5, specified quartz sand with grain size not more than 2.5 mm 68–71.
EFFECT: increase in linear expansion, compressive strength.
