Abstract

L'invention se rapporte au domaine de l'industrie minière et peut être utilisée afin de forer des puits. Le dispositif comprend un corps que l'on descend dans un manchon blindé dans un puits avec un outil de forage, un mécanisme de prise sous forme de mâchoires de prise à l'extérieur du corps, un moteur hydraulique avec un arbre creux d'entraînement pour la rotation de l'outil de forage, et un actionneur de déplacement axial de l'arbre creux de outil de forage sous forme d'un vérin hydraulique ou pneumatique vertical disposé le long de l'axe du corps au-dessus du moteur hydraulique. L'outil de forage comprend des parties inférieure et supérieure qui sont chacune disposées sur leur arbre creux de manière à tourner dans des directions opposées par rapport à l'arbre d'entraînement du moteur hydraulique et coaxialement à celui-ci. Des conduites haute pression passent à travers le manchon afin d'envoyer un milieu de travail gazeux ou liquide vers le moteur hydraulique, vers le vérin pneumatique ou hydraulique vertical, vers les vérins hydrauliques ou pneumatiques des mâchoires de prise, et vers les canaux d'alimentation en milieu de travail. Les canaux d'alimentation en milieu de travail sont formés dans la partie inférieure du corps et dans l'outil de forage. L'invention permet d'augmenter la fiabilité de fonctionnement du dispositif tout en augmentant la productivité.
