摘要：NOVELTY - The system has a drilling adaptor comprising an inner thread drilling rod adaptor and an external thread drilling rod adaptor. The external thread drilling rod adaptor is provided with an information connector. The inner thread drilling rod adaptor includes another information connector corresponding to the former information connector. The latter information connector includes an information contact body. The information contact body and another information contact body are mutually connected, where the former and the latter information contact bodies form multiple transmission channels. USE - Real-time control drilling system for a deep well and a super deep well of mining petroleum and natural gas. ADVANTAGE - The system conveys drilling information from a bottom part of the well to the ground control device via the transmission medium, adopts a relay to ensure signal transmission under a deep well and a super deep well and forms a real-time control of the bottom part of the well and a ground device. DESCRIPTION OF DRAWING(S) - The drawing shows a partial sectional view of a real-time control drilling system for a deep well and a super deep well of mining petroleum and natural gas.
