Дл изучени вли ни композиции на антифрикционные свойства буровых растворов проводилось испытание смесей разного состава. Испытание проводили на приборе, аналогичном КТК-2 по коэффициенту трени пары (сталь-глиниста корка). Композици вводилась в исходный буровой растворе количестве 0,1 об.%. Результаты испытаний за вл ем ых смесей, а также To study the effect of the composition on the antifriction properties of drilling fluids, mixtures of different compositions were tested. The test was carried out on a device similar to KTK-2 in terms of friction coefficient of a pair (steel-clay peel). The composition was introduced into the original drilling fluid in an amount of 0.1 vol%. Test results for inventive mixtures as well as
