FIELD: oil and gas production. ^ SUBSTANCE: invention aims at hardening (inertisation) neutralisation of drilling waste (spent clay mud and drilling sludge, and other core boring), containing mineral oil, heavy metals, surfactants and other contaminants. The drilling waste inertisation composition contains, wt %: cement 40-80; natural silica gel 20-60; 20% liquid glass 10-20 of a dry setting material. ^ EFFECT: lower labour input for preparing the drilling waste inertisation composition for neutralisation and recycling. ^ 3 tbl, 3 ex |
