METHOD OF RECEPTION AND TRANSMISSION OF DATA FROM WELL BOTTOM TO SURFACE BY ELECTROMAGNETIC COMMUNICATION CHANNEL BY ROCK USING SUPERCONDUCTING QUANTUM INTERFERENCE DEVICE

摘要

FIELD: oil and gas industry.;SUBSTANCE: method of reception and transmission of data from well bottom to the surface by wireless communication channel by electromagnetic method includes transmitting antenna located in well bottom on string of drilling tool. Antenna serves as a source of electromagnetic field. Receiving antenna connected to input of superconducting quantum interference device is located on day surface. In order to transmit data in well bottom low-frequency alternating amplitude or phase modulated electromagnetic radiation is generated.;EFFECT: increasing range of communication and transmitting of larger data volume due to possibility of increase in data signal carrier frequency.;4 cl, 1 dwg
