CA 2318853

There is disclosed an improved downhole steerable motor assembly (5) and related method. A problem in known assemblies is that the distance from a bent housing bend axis to the face of a drill bit needs to be kept relatively short resulting in the length of the bearing package and its thrust capacity being restricted. Accordingly, the invention provides a downhole motor assembly (5) comprising a motor (115), at least one thrust bearing (116) and a bent portion (117), the assembly (5) having a first end (135) and a second end (140), the first end (135) being closer to surface than the second end (140), in use, wherein the bent portion (117) is closer to the second end (140) than is the at least one thrust bearing (116).

La présente invention concerne, d'une part un modèle perfectionné d'ensemble moteur orientable pour fond de puits (5), et d'autre part les procédés correspondants. L'un des problèmes rencontrés sur de tels ensembles est que l'écart entre l'axe de coudage d'un carter coudé et le trépan doit rester relativement court, ce qui limite la longueur du carter de palier et sa résistance à la poussée. L'invention porte ainsi sur un ensemble moteur de fond de puits (5) comprenant un moteur (115), au moins un palier de butée (116) et un coude (117). L'ensemble (5) est défini par une première extrémité (135) et une seconde extrémité (140). Pour l'utilisation, la première extrémité (135) est plus proche de la surface que la seconde extrémité (140). En outre, le coude (117) est plus proche de la seconde extrémité (140) que le palier de butée (116) considéré.
