FIELD: oil and gas industry.
SUBSTANCE: invention refers to the area of oil and gas industry, namely to construction of oil and gas wells and can be used for manufacturing of cementing slurry used for wells fixation. Cementing slurry contains cement, hydroxyethyl cellulose, plasticizing agent, foam suppressant and additionally contains synthetic fibers with diameter 0.001-0.1 and length 1-20 mm, expansion admixture with the following ratio, weight ratio: cement - 100; hydroxyethyl cellulose- 0.2-0.4; plasticizing agent - 0.1-0.5; foam suppressant - 0.2; synthetic fibers - 0.1-4; expansion admixture -0.1-20; water - 49-51.
EFFECT: increased surface of full contact of hardened cementing slurry with ground and casing string.
