Abstract
L'invention concerne un procédé d'évaluation de la capacité d'un fluide de forage à consolider une paroi de puits et à briser la roche environnante. Le procédé comprend : en fonction de la résistance au cisaillement de surfaces de contact d'échantillon, de la résistance au cisaillement entre les surfaces de contact d'échantillon après qu'un fluide de forage ait agi sur celles-ci, et d'un angle de frottement entre les surfaces de contact d'échantillon après que le fluide de forage ait agi sur celles-ci, calcul d'une augmentation d'amplitude dans la résistance au cisaillement provoquée par le fluide de forage et d'une augmentation d'amplitude de l'angle de frottement provoquée par le fluide de forage, et évaluation de la capacité du fluide de forage à consolider une paroi de puits et à briser la roche environnante en fonction d'une augmentation d'une force de cohésion entre les surfaces de contact d'échantillon après que le fluide de forage ait agi sur celles-ci et de l'augmentation d'amplitude dans la résistance au cisaillement provoquée par le fluide de forage et de l'augmentation d'amplitude dans l'angle de frottement provoqué par le fluide de forage. Le procédé d'évaluation de la capacité d'un fluide de forage à consolider une paroi de puits et à briser la roche environnante permet une évaluation quantitative de la capacité d'un fluide de forage à améliorer la résistance au cisaillement entre des blocs brisés, et fournit des paramètres mécaniques fiables pour la stabilité de parois de puits dans des strates fracturées.
