Abstract

В заявке описан способ электромагнитной телеметрии, включающий кодирование скважинных данных в единый поток данных; разделение единого потока данных на множество отдельных потоков данных; преобразование каждого отдельного потока данных в соответствующее отдельное колебание с использованием заданной схемы цифровой модуляции, причем фазе и/или частоте каждого колебания присваивается уникальная величина или уникальный неперекрывающийся диапазон величин; суммирование всех отдельных колебаний для формирования суммарного колебания и передачу из забоя скважины несущей волны электромагнитной телеметрии, содержащей суммарное колебание.
