Abstract

Drilling varillaje, for exploration of the subsoil, with double concentric pipe and reverse circulation. It is formed by two tubes (1), the outer (2) with concrete thread generally of standard a. P. I. Male-female, that fits inside the interior tube. This tube (3) has one of the smooth extremes and the other one is overwhelmed, being provided with toric closing rings (4), so that when connecting one with another, a sealed gasket is left. The interior pipes are centered with respect to the exteriors through a piezassoldadas in the extremos or centrators (5) and that rest in a highlights of the external tubes.
