Description
Известны тампонажные материалы дл закреплени калий-магниевых солевых пород на основе каустического магнезита и-хлормагниевого или сульфатномагниевого рассола . Предлагаемый тампонажный материал отличаетс тем, что к каустическому магнезиту , затворенному на хлормагниевом или сульфатномагниевом рассоле, добавл ют медный купорос в количестве 4-6 вес. ед. от веса каустического магнезита. Это позвол ет замедлить схватывание тампонажного материала и повысить механическую прочность и устойчивость в агрессивных средах, какими вл ютс рассолы в скважинах , пересекающих надсолевые породы и породы продуктивной калийно-магниевой толщи . Тампонажный материал был испытан в скважинах, расположенных на шахтных пол х Соликамского и 1-го Березниковского калийных рудников. Материал имел следующий состав: Каустический магнезит II кл. (з-д «Магнезит г. Сатка) 100 вес. ед. Хлормагниевый 28о/о-ный 60-80 вес. ед. рассол Медный купорос 2-5 вес. ед. (CuSOi-SHaO) В результате испытаний было установлено, что тампонажный раствор твердеет в течение 30-72 час после тампонировани с образованием прочного цементного камн (предел прочности на сжатие 80-100 кг/см). Кроме того, сокращаетс врем на производство тампонажа в 2,5 раза и повышаетс качество тампонажных работ. Предмет изобретени Тампонажный материал дл закреплени калий-магниевых солевых пород на основе каустического магнезита и хлормагциевого или сульфатномагниевого рассола, отличающийс тем, что, с целью повышени коррозионной устойчивости тампонажного материала и качества тампоналсных работ в агрессивных средах, в него введена добавка медного купороса в количестве 4-6 вес. ед. от веса каустического магнезита.Cementing materials for fixing potassium-magnesium salt rocks based on caustic magnesite and chlorine magnesium or magnesium sulphate brine are known. The proposed grouting material is distinguished by the fact that copper sulphate in an amount of 4-6 wt. Is added to caustic magnesite shuttered on chlorine-magnesium or sulfate-magnesium brine. units from the weight of caustic magnesite. This makes it possible to slow down the setting of the cement material and to increase the mechanical strength and stability in aggressive media, such as brines in wells crossing the over-salt and productive potassium-magnesium strata. Cement material was tested in wells located on the mine fields of Solikamsky and the 1st Berezniki potash mines. The material had the following composition: Caustic magnesite II cl. (zd “Magnesite Satka”) 100 weight. units Chloromagnesium 28o / o-ny 60-80 weight. units brine Blue sulphate 2-5 wt. units (CuSOi-SHaO) As a result of the tests, it was found that the cement slurry hardens within 30-72 hours after tamping to form a durable cement stone (compressive strength of 80-100 kg / cm). In addition, the time for production of the grouting is reduced by 2.5 times and the quality of the grouting works is improved. Subject of the invention Cement material for fixing potassium-magnesium salt rocks based on caustic magnesite and chlorine-magnesium or magnesium sulphate brine, characterized in that in order to increase the corrosion resistance of the cement material and the quality of tamponal works in corrosive media, the addition of copper vitriol in the amount of 4 -6 weight units from the weight of caustic magnesite.
