A continuous congruent length of stranded flexible Drilling Energy Transfer Member (DETM) to transfer and balance action/reaction forces between an energy source and a working tip (9) such that torque, tensile, compression and self supporting forces are constrained while the DETM operates in multiple positions of tight curvature and straight run. The DETM having a core load cell with a plurality of strands (13, 14, 16) sized and layered at a helical angle and an outer wrap load cell with a second plurality of strands (17, 18) sized and layered at a helical angle.
Cette invention se rapporte à un segment cohérent continu d'un élément de transfert d'énergie de forage (DETM) flexible toronné, servant à transférer et à équilibrer les forces d'action/réaction entre une source d'énergie et une pointe de travail (9), pour que les forces de couple, de tension, de compression et autoporteuses soient restreintes, pendant que l'élément DETM travaille dans de multiples positions en courbe serrée et en ligne droite. Cet élément DETM comprend une cellule de charge noyau ayant un groupe de plusieurs torons (13, 14, 15) dimensionnés et disposés en couches selon un angle hélicoïdal, ainsi qu'une cellule de charge d'enveloppe extérieure ayant un second groupe de plusieurs torons (17, 18) dimensionnés et disposés en couches selon un angle hélicoïdal.
