A method of assaying work of a bit (10) of a given size and design comprises the steps of drilling a hole with the bit (10) from an initial point (I) to a terminal point (T) and recording the distance between the initial and terminal points. Electrical incremental actual force signals (18) are generated, each corresponding to a force of the bit (10) over a respective increment of the distance between the initial and terminal points. Electrical incremental distance signals (14) are also generated, each corresponding to the length of the increment for a respective one of the incremental actual force signals (18). The incremental actual force signals and incremental distance signals are processed to produce a value corresponding to the total work done by the bit in drilling from the initial point to the terminal point. Using such a work assay, a number of other downhole occurrences and/or conditions can be assayed.

L'invention concerne un procédé de test du travail d'un trépan (10) de taille et forme données, procédé qui consiste à effectuer un forage avec le trépan (10), d'un point initial I à un point terminal T, et à enregistrer la distance entre ce point initial et ce point terminal. Des signaux électriques (18) relatifs à une pression réelle progressive sont générés, chacun d'eux correspondant à une pression du trépan (10) sur une progression respective de la distance entre le point initial et le point terminal. Des signaux électriques (14) relatifs à une distance progressive sont également générés, chacun d'eux correspondant à la longueur de progression d'un des signaux respectifs (18) de la pression réelle progressive. Les signaux relatifs à la pression réelle progressive et à la distance progressive sont traités en vue d'obtenir une valeur correspondant à la totalité du travail effectué par le trépan du point initial au point terminal de forage. A l'aide de ce test de travail, il est possible d'analyser d'autres manifestations et/ou conditions de fond de trou.
