Title (EN) APPARATUS AND METHOD FOR MEASURING THE CHARACTERISTICS OF AN OILFIELD FLUID OR THE LIKE
(FR) APPAREILET PROCEDE PERMETTANT DE MESURER LES CARACTERISTIQUES D'UN FLUIDE DE CHAMP DE PETROLE OU ANALOGUE
Abstract: front page image
(EN)A method of determining the shear threshold of a drilling mud consists in placing a detecting head with a spherical surface near to a porous wall, in pouring the drilling mud around the detecting head, in forcing the mud to pass through the porous surface so as to form a mud cake above the porous surface and around the detecting head which has a diameter D, and in measuring both the time required for the mud cake to reach a measurable or pre-determined height, and also the torque opposing rotation of the detecting head corresponding to that height.
(FR)L'invention concerne un procédé permettant de déterminer le seuil de cisaillement d'une boue de forage. Ce procédé consiste à placer une tête de détection pourvue d'une surface sphérique à proximité d'une paroi poreuse, à verser la boue de forage autour de la tête de détection, à exercer une contrainte sur la boue afin de traverser la surface poreuse et de former un cake de boue au-dessus de ladite surface poreuse et autour de la tête de détection, laquelle a un diamètre D, enfin à mesurer à la fois le temps que prend le cake à atteindre une hauteur mesurable ou prédéterminée et la rotation opposée au couple de la tête de détection correspondant à ladite hauteur.
