Abstract

В заявке описан способ введения добавок в нефтяные, газовые скважины, а также скважины для закачивания воды в пласты месторождений, а также в трубопроводы, в твердом виде в любые участки скважин, кроме дна. Способ применяется с использованием гранул, характеризующихся плотностью, достаточной для суспендирования гранул в верхней жидкой фазе, нижней жидкой фазе, а также на границе двух жидких фаз внутри ствола скважины. Гранулы готовятся из гранульной матрицы, такой, например, как этоксилированный воск, а также утяжеляющего агента и добавки. Посредством варьирования количества утяжеляющего агента, плотность гранулы также может варьироваться, что способствует ее временному нахождению в выбранном участке скважины в течение времени, достаточного для доставки добавки в выбранный участок внутри скважины.Международная заявка была опубликована вместе с отчетом о международном поиске.
