ни смеси 60 г каустического магнезита обрабатывают 60 г ортофосфорной кислоты при перемешивании.Neither a mixture of 60 g of caustic magnesite is treated with 60 g of orthophosphoric acid with stirring.
В соответствии с приведенным примером приготовл ют различные варианты раствора, отличающиес соотношением компонентов, результаты исследовани которых указаны Р таблице.In accordance with the example given, different solutions are prepared, differing in the ratio of components, the results of which are indicated by the P table.
Анализ приведенных данных показы- вает, что предлагаемый раствор по сравнению с известным обладает меньшими значени ми показател фильтраци и скорости коррозии, а также более высокой плотностью.The analysis of the presented data shows that the proposed solution in comparison with the known one has lower values of filtration index and corrosion rate, as well as a higher density.
Минимальное отклонение от соотношений каустический магнезит:орто- фосфорна кислота (1:1) составл ет 1:(1-0,8) (опыты 10,11).The minimum deviation from the ratios of caustic magnesite: orthophosphoric acid (1: 1) is 1: (1-0.8) (runs 10,11).
В опытах 7 и 8 улучшение свойств бурового раствора не наблюдаетс , в основном за счет изменени соотношени каустического магнезита и ортофосфорной кислоты, которое составл е 0,5 и 2,0 соответственно, в опытах 5 и 9 - из-за изменени пор дка ввода ингредиентов.In tests 7 and 8, improvement in the properties of the drilling fluid was not observed, mainly due to the change in the ratio of caustic magnesite and orthophosphoric acid, which was 0.5 and 2.0, respectively, in tests 5 and 9, due to the change in the order of input of ingredients .
Использование, например, КОИ в ка честве щелочи при заданных соотношени х компонентов не обеспечивает достижение поставленной цели.The use of, for example, KOI as an alkali at given ratios of the components does not ensure the achievement of the goal.
В опытах 1-4, 6, 1U, 11 показана возможность достижени цели изобретени при концентраци х ингредиентов во всем диапазоне их концентраций.Experiments 1-4, 6, 1U, 11 show the possibility of achieving the goal of the invention with concentrations of ingredients in the whole range of their concentrations.
