METHOD OF TERRESTRIAL DATA TRANSFER AND RECEIPT IN DRILLING PROCESS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC E21B47/12 H04B3/54 

FIELD: oil and gas industry.

SUBSTANCE: method is suggested for terrestrial data transfer and receipt in drilling process, which includes receipt of data from sensors of the bottomhole telemetry system, terrestrial data transfer with their further decoding and data transfer to the registers of information users. At that data transfer is carried out through cables of the power lines feeding the registers of information users and surface sensors installed at the drilling site and pumping equipment. Besides receivers receiving data from sensors of the bottomhole telemetry system, surface sensors, the basis computer and receivers in the registers of information users are equipped with electrical PLC-modems with the embedded network protocol including an interface block and programming interface units for data receipt and transfer through power lines. The device for implementation of the above method is also claimed.

EFFECT: ensuring on-line monitoring of the remote registers distributed at the drilling site, improving reliability and operating convenience of the terrestrial data transfer system.
