FIELD: exploring drilling.
SUBSTANCE: invention relates to the plugging composition used in cementing drilling wells that comprises caustic magnesite, double superphosphate, starch reagent, sodium tripolyphosphate and water, and a waste-slag in manufacturing magnesium as a cementing base in the following ratio of components, mass. p. p.: indicated waste in manufacturing magnesium, 1.0; caustic magnesite, 0.14-0.76; double superphosphate, 0.2; starch reagent, 0.007; sodium tripolyphosphate, 0.06, and water, 0.6-1.0. Invention can be used in manufacturing cementing conducting agents and technical columns in petroleum and gaseous wells. Invention provides decreasing cost in producing the cementing deep wells based on using mixtures from waste in magnesium manufacturing as components of plugging mixture, and partial solving the ecological problem for utilizing waste in magnesium manufacturing also.
EFFECT: improved and valuable properties of plugging composition.
