Abstract
1. Способ передачи информации по электромагнитному каналу связи, включающий возбуждение электрического тока в породе, окружающей нижнюю часть колонны бурильных труб (колонна) при помощи ЭДС автономного генератора, подключенного к колонне и изолированному от колонны коаксиальному кольцу, кодирование забойной информации, отличающийся тем, что в верхнюю компоновку колонны вводят дополнительное изолированное от колонны коаксиальное кольцо и с этого кольца осуществляют съем величины переменного потенциала напряжения, наводимого в породе текущим током, генерируемым излучающим кольцом, при этом величину указанного потенциала модулируют управляемой в соответствии с кодированной забойной информацией ЭДС автономного генератора.2. Устройство для передачи информации по электромагнитному каналу связи, содержащее автономный генератор, проводящее коаксиальное изолированное от колонны бурильных труб (колонна) кольцо, установленное в нижней части колонны, и устройство кодирования и управления ЭДС автономного генератора, а также блок регистрации и декодирования получаемой информации возбуждения электрического тока в колонне и в породе, окружающей колонну, отличающееся тем, что в верхнюю компоновку колонны введено дополнительное проводящее коаксиальное изолированное от колонны кольцо, установленное с возможностью регистрации изменения напряжения между этим измерительным кольцом и колонной.1. A method of transmitting information through an electromagnetic communication channel, including the excitation of an electric current in the rock surrounding the lower part of the drill pipe string (string) using an EMF of an autonomous generator connected to the string and a coaxial ring isolated from the string, coding downhole information, characterized in that an additional coaxial ring isolated from the column is introduced into the upper arrangement of the column, and the variable voltage potential induced in the rock is removed from this ring the current generated by the radiating ring, while the magnitude of the indicated potential is modulated by the EMF of the autonomous generator controlled in accordance with the downhole encoded information. 2. A device for transmitting information via an electromagnetic communication channel, containing an autonomous generator, conducting a coaxial ring isolated from the drill pipe string (string), mounted in the lower part of the string, and an encoding and control device for the emf of the autonomous generator, as well as a unit for recording and decoding the received electrical excitation information current in the column and in the rock surrounding the column, characterized in that an additional conductive coaxial isolation is introduced into the upper arrangement of the column e from the column is a ring installed with the possibility of recording voltage changes between this measuring ring and the column.
