Abstract
Отложение асфальтенов и/или нефтяных восков может быть ингибировано и/или асфальтены и/или нефтяные воски могут быть удалены из скважины, трубы или емкости путем контактирования асфальтена и/или нефтяного воска или скважины, трубы или емкости рядом с местом, где ожидают отложения асфальтена и/или нефтяного воска, с растворителем, содержащим, по меньшей мере, одно соединение формулы (I): R-(AO)-OOC-(CH)-Ph-(R), где Rозначает от Cдо Суглеводородную группу; АО означает алкиленоксигруппу и может варьироваться вдоль (поли)алкиленоксицепи; n равно 0 или от 1 до 100; m равно 0, 1 или 2; и Ph означает фенильную группу, которая может быть замещена группами (R), где каждый из Rнезависимо друг от друга означает от Cдо Салкильную или алкоксигруппу; и р равно 0, 1 или 2, и последующего удаления растворителя с размягченными, растворенными или диспергированными асфальтенами и/или нефтяными восками из скважин, труб или емкостей.Международная заявка была опубликована вместе с отчетом о международном поиске.
