Title
(EN) MUD SETTLEMENT DETECTION TECHNIQUE BY NON-DESTRUCTIVE ULTRASONIC MEASUREMENTS
(FR) TECHNIQUE DE DÉTECTION DE DÉCANTATION DE BOUE AU MOYEN DE MESURES PAR ULTRASONS NON DESTRUCTIVES
Abstract
(EN)
Systems and methods of determining settlement characteristics of a drilling mud are disclosed. Conditions under which heavier elements of the drilling mud settle under the influence of gravity can be determined. Samples of drilling mud can be placed in testing cells, and ultrasonic test pulses can be transmitted through the samples. Responses to the test pulses can be detected and compared to other responses detected at different vertical positions within the testing cell. Settlement can be detected when the responses from different vertical positions are generally dissimilar. An environmental temperature of the testing cell can be changed over a testing time interval, and a settlement temperature can be determined by detecting a divergence in the responses from different vertical positions.

La présente invention concerne des systèmes et des procédés de détermination de caractéristiques de décantation d'une boue de forage. Des conditions dans lesquelles des éléments plus lourds contenus dans la boue de forage se déposent sous l'influence de la pesanteur peuvent être déterminées. Des échantillons de boue de forage peuvent être placés dans des cellules de test, et des impulsions de test par ultrasons peuvent être transmises à travers les échantillons. Les réponses aux impulsions de test peuvent être détectées et comparées à d'autres réponses détectées au niveau de différentes positions verticales à l'intérieur de la cellule de test. Une décantation peut être détectée lorsque les réponses en provenance de différentes positions verticales sont généralement différentes. Une température de l'environnement de la cellule de test peut être modifiée sur un intervalle de temps de test, et une température de décantation peut être déterminée par détection d'une divergence dans les réponses en provenance de différentes positions verticales.
