Title
(EN) APPARATUS FOR EVALUATING ROCK PROPERTIES WHILE DRILLING USING DRILLING RIG-MOUNTED ACOUSTIC SENSORS
(FR) APPAREIL POUR ÉVALUER LES PROPRIÉTÉS D'UNE ROCHE PENDANT LE FORAGE AU MOYEN DE CAPTEURS ACOUSTIQUES MONTÉS SUR UN APPAREIL DE FORAGE
Abstract
(EN) Apparatus (30) for identifying rock properties in real-time during drilling, are provided. An example of an embodiment of such an apparatus (30) includes one or more acoustic sensors (33, 301, 321, 351) positioned to detect drill sounds emanating from the drill bit (101 ) and the rock encountered during drilling operations, connected to select components of a drilling rig to maximally pick up the drill sounds of the drill bit (101 ) engaging rock during drilling operations. The apparatus (30) also includes an inductive telemetry (300), wireless telemetry (320), or wired, transmitting system (350). The apparatus (30) also includes a computer (306) to analyze the acoustic signals received from the acoustic sensors (33, 301, 321, 351) through the respective transmitting system for lithology type and petrophysical properties (415 ).
(FR) L'invention concerne un appareil (30) pour identifier des propriétés d'une roche en temps réel pendant le forage. Un exemple d'un mode de réalisation d'un tel appareil (30) comprenant un ou plusieurs capteurs acoustiques (33, 301, 321, 351) disposés de manière à détecter les sons de forage émanant du trépan (101) et de la roche produits pendant les opérations de forage, connectés pour sélectionner des composants d'un appareil de forage afin de collecter de manière optimale les sons de forage du trépan (101) venant en contact avec la roche pendant les opérations de forage. L'appareil (30) comprend également un système de télémétrie inductive (300), un système de télémétrie sans fil (320), ou un système de transmission câblé (350). L'appareil (30) comprend également un ordinateur (306) pour analyser les signaux acoustiques reçus depuis les capteurs acoustiques (33, 301, 321, 351) par l'intermédiaire du système de transmission respectif pour obtenir des propriétés pétrophysiques (415) et de type lithologie.
