Description
Предлагаетс способ замедлени схватывани цементного раствора, предназначенный дл производства тампонажных работ в глубоких нефт ных и газовых скважинах.A method for slowing down the setting of cement slurry is proposed, designed to perform cement works in deep oil and gas wells.
В качестве замедлител сроков схватывани цементных растворов примен ют кислую калиевую соль виннокаменной кислоты (винный камень ), котора вл етс побочным продуктом винного производства ц составл ет до 60% бочкового остатка на производстве бочковый остаток в тоМ же количестве.Acid potassium salt of tartaric acid (tartar), which is a by-product of wine production, accounts for up to 60% of the barrel residue in the production of barrel residue in the same quantity as a retarder for the setting time of cement mortars.
Отличительна особенность способа заключаетс s том, что с целью замедлени схватывани при температуре не ниже 80°, используетс кисла калиева соль виннокаменной кислоты KHC-sHiOi; (винный камень) г, количестве 0,1-0,5% веса расчетного количества сухого цемента.A distinctive feature of the method is that in order to slow down the setting at a temperature of at least 80 ° C, the acid potassium tartaric acid salt KHC-sHiOi is used; (cream of tartar), an amount of 0.1-0.5% by weight of the calculated amount of dry cement.
Положительным фактором способа вл етс то, что винный камень эффективно действует как замедлитель сроков схватывани цементных растворов и одновременно увеличивает прочность цементного камн . Винный камень, вл сь отходом винного производства, недефицитен и сгоимость его значительно ниже стоимости виннокаменной кислоты.A positive factor of the method is that tartar effectively acts as a time delay for the setting of cement mortars and at the same time increases the strength of the cement stone. Tartar, which is a waste of wine production, is not deficient and its cost is significantly lower than the cost of tartaric acid.
