Title
(EN) A VUGULAR LOSS SIMULATING VUG TESTER FOR SCREENING AND EVALUATION OF LCM PRODUCTS
(FR) TESTEUR DE VACUOLE SIMULANT UNE PERTE VACUOLAIRE POUR LE CRIBLAGE ET L'ÉVALUATION DE PRODUITS COLMATANTS
Abstract
(EN)
An apparatus to simulate fluid loss through vugs in formations includes a housing defining an inner volume, and having a first end and a second end. The inner volume represents an inner region of a wellbore formed in a formation containing a vugular loss zone. The housing can receive wellbore fluid within the inner volume. A first cover late, which sealingly covers the first end, represents a first volumetric boundary of the inner region of the wellbore. A second cover plate, which sealingly covers the second end, represents a second volumetric boundary of the inner region of the wellbore. An outlet in the second cover plate can be switched between open and closed states. The outlet in the open state represents a vug in the inner wall of the wellbore. The apparatus includes a pressure port configured to transmit fluidic pressure in a direction of gravity within the inner volume and to apply the fluidic pressure to the wellbore fluid within the inner volume.
(FR)
L'invention concerne un appareil pour simuler une perte de fluide à travers des vacuoles dans des formations, qui comprend un boîtier délimitant un volume interne et présentant une première extrémité et une seconde extrémité. Le volume interne représente une région interne d'un puits de forage formé dans une formation contenant une zone de perte vacuolaire. Le boîtier peut recevoir un fluide de puits de forage à l'intérieur du volume interne. Une première plaque de recouvrement, qui recouvre de manière étanche la première extrémité, représente une première limite volumétrique de la région interne du puits de forage. Une seconde plaque de recouvrement, qui recouvre de manière étanche la seconde extrémité, représente une seconde limite volumétrique de la région interne du puits de forage. Un orifice de sortie dans la seconde plaque de recouvrement peut être basculé entre des états ouvert et fermé. L'orifice de sortie dans l'état ouvert représente une vacuole dans la paroi interne du puits de forage. L'appareil comprend un orifice de pression conçu pour transmettre une pression fluidique dans une direction de gravité à l'intérieur du volume interne et pour appliquer la pression fluidique au fluide de puits de forage à l'intérieur du volume interne.
