Abstract

Inventia se refera la un racord de siguranta care este montat între o carotiera sau o sapa de foraj si o garnitura de prajini în timpul forajului unor gauri de adâncime relativ mica ori între niste scule de instrumentatie si garnitura de prajini în timpul rezolvarii unor accidente tehnice. Racordul de siguranta cuprinde un corp fixat într-o reductie asigurându-se functionalitatea în foraj prin niste stifturi prin a caror forfecare este asigurata salvarea garniturii de prajini, la care desurubarea se face în sensul de însurubare al garniturii de foraj.The invention relates to a safety connection which is mounted between a carcass or a drilling hole and a gasket during the drilling of deep holes relatively briefly between some instrumentation tools and the gasket during the solving of technical accidents. The safety connection comprises a body fixed in a reduction providing the drilling functionality by means of some stiffeners by means of which shearing of the gasket is provided, in which the unscrewing is made in the direction of screwing of the drill bit.
