Document Type and Number:
WIPO Patent Application WO/2022/217779
Kind Code:
A1
Abstract:
A downhole-to-ground logging communication and control apparatus, comprising a ground portion (10) and a downhole portion (20), wherein the ground portion (10) is provided with an atomic magnetometer receiving apparatus (1), and a quantum detection device (2), from which quantum data is read; the downhole portion (20) comprises an electromagnetic wave emitting system (3); and the electromagnetic wave emitting system (3) is used for encoding a signal detected downhole, and emitting same by means of an electromagnetic wave. The apparatus has the characteristics of high detection sensitivity, a wide operation temperature range, low operation energy consumption, a small occupied volume, a large channel width, a high transmission rate and a low cost, and has obvious advantages in terms of the wireless transmission of downhole-to-ground data communication.
