Abstract
Предлагаются искусственные частицы, содержащие химические реагенты, пригодные для применения в скважинах. Преимущество частиц заключается в их способности к химической обработке скважины, например, для удаления фильтрационной корки на стенках скважины. Варианты осуществления настоящего изобретения повышают производительность скважины посредством борьбы с поступлением песка в скважину и/или повышения проницаемости гравийной набивки. Предлагаются также способы применения частиц и гравийной набивки, содержащей упомянутые частицы.
