Description
Известны тампонажные безобжиговые цементы, которые имеют Низкую температуру схватывани , а поэтому малопригодны дл тамнонажных работ в сверхглубоких скважинах.Known for cementing bezbigovye cements, which have a low setting temperature, and therefore unsuitable for cement work in ultra-deep wells.
Предлагаемый тампонажный цемент может быть применен дл изол ционных работ в скважинах с температурами на забое 200-300° и давлением более 500 атм. Такие свойства цемента достигнуты путем применени нового в жущего вещества, состо щего из смеси тонкоизмельченных 1СИСЛОГО граиилурованного металлургического шлака и кварцево-магнетитового песка с содержанием магнетнта 18-20%.The proposed cementing cement can be used for insulation works in wells with bottomhole temperatures of 200-300 ° C and pressure over 500 atm. Such properties of cement are achieved by applying a new essential substance consisting of a mixture of finely divided 1 SILICATE metallurgical slag and quartz-magnetite sand with a magnet content of 18-20%.
Сроки и прочность схватывани регулируютс в широких иределах путем изменени отношени кислого шлака (от 80 до 20%) к кварцевомагнетитовому песку.The timing and strength of the setting are regulated in wide ranges by changing the ratio of acidic slag (from 80 to 20%) to quartz-magnetite sand.
Предлагаемый цемент при тверденни увеличиваетс в объеме и прочно схватываетс с металлом. При хранении в обычных услови х цемент длительное врем не гидратирует.The proposed cement during solidification increases in volume and firmly adheres to the metal. When stored under normal conditions, the cement does not hydrate for a long time.
Предмет изобретени Subject invention
Тампонажиый безобжиговый цемент, -дл -скважин, отли-чающи и с - тем, что, с целью иснользовани его в скважинах;, с забойной температурой 200-300° и давлением более 500 атм, в его состав введены измельченный кислый гранулированный .металлургический шлак и кварцево-магнетитовый песок, содержащий в своем составе 18-20% магнетита, причем компоненты введены в соотношении от 80 до 20% щлака,Tamponage unburned cement, dl-well, distinguishing and with the fact that, in order to use it in wells, with a bottomhole temperature of 200-300 ° and pressure over 500 atm, crushed acidic granulated metallurgical slag was added to its structure and quartz-magnetite sand, containing in its composition 18-20% magnetite, and the components are introduced in the ratio from 80 to 20% sclac,
