Description
II
Изобветение относитс к тампонажным растворам, предназначенным дл креплени скважин.The report relates to cement slurries designed to fix wells.
В насто щее врем известно много видов тампонажных растворов, содержащих комплексные добавки, регулирующие реологические, фильтрационные свойства и сроки схватывани цементных растворов.Currently, there are many types of cement slurries that contain complex additives that regulate the rheological, filtration properties and setting time of cement mortars.
Известны тампонажные растворы, состо 1дие из тампонажного цемента, воды и добавки, например натриевой соли пентаоксипимелиновой кислоты tQОднако такие добавки труднодоступны из-за отсутстви производства технического препарата и, следовательно , дорогосто щи.Cementing solutions are known, consisting of cement from cement, water and additives, for example sodium pentaoxypimelic acid tQ However, such additives are difficult to obtain due to the lack of production of a technical preparation and, therefore, are expensive.
Известен тампонажный раствор, содержащий , %: цемент 47,78, гематит 23,80, реагент 0,25 и вода 28,21 2.Known cement slurry containing,%: cement 47.78, hematite 23.80, reagent 0.25 and water 28.21 2.
Недостатками .этого раствора вл ютс плохие фильтрационные свойства , низка седиментационна устойчивость , кроме того, неудовлетворительна термо- и коррозионна стойкость .The disadvantages of this solution are poor filtration properties, low sedimentation stability, and, in addition, thermal and corrosion resistance are not satisfactory.
Известны тампонажные растворы, включающие тампонажный цемент, минеральную добавку, например глиеж, и воду 3.Known grouting solutions, including cement grouting cement, mineral additive, such as glial, and water 3.
Недостатками известного раствора вл ютс невозможность использовани его в услови х высоких температур , а значительные реологические The disadvantages of the known solution are the impossibility of using it in conditions of high temperatures, and considerable rheological
10 показатели раствора затрудн ют его прокачиваемость в течение длительного периода времени.10 solution performance makes it difficult to pump over a long period of time.
Цель изобретени - улучшение фильтрационных и реологических The purpose of the invention is to improve the filtration and rheological
s свойств и замедление схватывани в услови х высоких температур.s properties and slower setting in high temperature conditions.
Указанна цель достигаетс тем, что тампонажный раствор дополнительно содержит экстракт 3aranium rec20 tum при следующем соотношении компонентов, вес.%:This goal is achieved by the fact that the cement slurry additionally contains 3aranium rec20 tum extract with the following ratio of components, wt.%:
Тампонажный цемент 23-39 Глиеж23-29Grouting cement 23-39 Gliezh23-29
