Title
(EN) SYSTEM AND METHOD FOR MEASUREMENT WHILE DRILLING TELEMETRY
(FR) SYSTÈME ET PROCÉDÉ DE TÉLÉMÉTRIE PENDANT LE FORAGE
Abstract
(EN)
A system for transmitting information in a well comprises a tubular string disposed in the well and having a drilling fluid flowing therethrough. A pulser is disposed in the tubular string and transmits a pulse synchronization marker comprising a chirp signal. A surface controller, acting under programmed instructions, detects the chirp signal adjusts a signal decoding technique based on the detected chirp signal.
(FR)
L'invention concerne un système pour transmettre des informations dans un puits qui comprend un train tubulaire placé dans le puits et traversé par un fluide de forage. Un pulseur, placé dans le train tubulaire, émet un marqueur de synchronisation d'impulsions comprenant un signal chirp. Un contrôleur de surface, opérant selon des instructions programmées, détecte le signal chirp et ajuste une technique de décodage de signaux sur la base du signal chirp détecté.
