Description

леной воде приводит к коагул ции глй Тйр тШ частиц, которые при этом не гидра тйру;ютс , в результате чего поWBrfSeTCH воэм вводить в сое тав боИШеё7 ем при э твбЬёнии на пресной воде, количество глины. Соетйв гййеет наЧаль ую растекаемость по конусу АзНИИ в пределах 16-18 см, что без бсложнений доста.вить раствор по 3аливочной колонне к зоне поглощени . На выходе из заливочной djf6HBbn раствор диспергируют, напримёр гидравлически, струйным методом, найрабл й со скоростью не менее 10бм/ поток раствора на экран. При этом коа гулировавшие во врем  заТ1в5рёйги  к слившиес  в крупные глоОулы глйнисайе частицы раздел ютс  и св зывают воду, образу  структуру , плаотическа  прочность которой через 2 ч достигает 70-аО гс/см. , 11реимуие:ство данного состава дл  изол ции зон поглощений и способа его получени  Зайлючйетс  в повЁлиенных тамдонирунмцих свойствах раствора, высокой в зкости и пластической прочности структуры.Технико-зконсжический эффект от использовани  изобретени  достигаё тс  путей увеличени  результативноеТИ изол ционных операций,снижени  их чйЬла: и уменьшени  расхода глины и peia гентов . Ожидаемый экономический эффект на 1 операцию с применением 10 м раствора 1 составл ет 2-2,5 тыс.рублей, а при максимальном использовании изобретени  годовой экономический эффект достигает около 1 млн. рублей. In the case of water, coagulation of particles, which are not hydrated, leads to coagulation of the amount of clay by fresh water in the course of fresh water. Soytyv gayet the beginning of the flow on the cone of AzNII within 16-18 cm, that without complications to get a solution on the bulk column to the absorption zone. At the outlet of the djf6HBbn casting solution, the solution is dispersed, for example, hydraulically, using a jet method, at a speed of at least 10 bpm / solution flow onto the screen. At the same time, the particles that coagulated during the T1 – 5yyyy to the fused into the large globes of the glacine are separated and bind water, forming a structure, the plasma strength of which after 2 hours reaches 70 aO gf / cm. , 11: This composition for isolating the absorption zones and the method of its production is contained in the retention properties of the solution, high viscosity and plastic strength of the structure. Technical effect of the invention achieves ways to increase the efficiency of insulation operations and reduce their effectiveness: and reducing clay and peia consumption. The expected economic effect on 1 operation using 10 m of solution 1 is 2-2.5 thousand rubles, and with the maximum use of the invention, the annual economic effect reaches about 1 million rubles.
