Abstract

Изобретение относится к полиамидным бусинкам или гранулам и к способу производства таких бусинок, а также к их применению в качестве поддерживающего материала для подземных природных или искусственных трещин земной коры, особенно используемых для добычи углеводородов, таких как нефть или природный газ. Изобретение относится к полиамидным бусинкам, имеющим сферическую или эллипсоидную форму и имеющим поверхность без вогнутых частей, преимущественно имеющих одинаковую форму, средний диаметр менее чем или равный 1,7 мм и пористость менее чем 0,1 мл/г. Изобретение также относится к способу производства таких бусинок с использованием сопутствующего приспособления для резки.
