Abstract: A wireless downhole information transfer system is adapted to operate in wells (well bores), and in particular in wells for the Oil & Natural Gas and Geothermal Industry. The information transfer system comprises an elongated tubing (completion) having several tubing sections comprising a first and a last end tubing section, an information signal generator placed at or near the first tubing section of the elongated tubing. The information signal generator is designed as a torsional wave generator for transmission of a torsional wave information signal along the elongated tubing, and an information signal receiver arranged at or near the last tubing section of the elongated tubing, wherein the elongated tubing between the signal generator and the signal receiver constitutes a carrier for transmission of the information signal between the signal generator and the signal receiver.

Abstract: A mail processing method and apparatus, an electronic device and a storage medium are provided. The method comprises: acquiring, in response to detection of a preset operation triggered based on a target mail, at least one collaborative user; and sharing a target link corresponding to the target mail with each collaborative user, in order that each collaborative user reads the target mail based on the target link and/or edits the target mail based on the target link. The target mail comprises at least one of: content of the target mail and content of a draft reply to the target mail.
