Abstract

See full text

Described herein is a “cross-over” connector that can be used with core barrel outer tubes to prevent damage and destruction when they are connected to one another by automated equipment on a rig floor, for example, automated rig-floor torque wrenches. Standard core barrel outer tubes having a pin connector and a box connector are modified by adding “cross-over” sub elements to the pin and box connectors to increase their effective strength. The sub elements include portions which engage respective ones of the pin and box connections. The sub elements are designed to be the contact points for the automated equipment, so that it they are damaged, they can readily be replaced at a lower cost when compared to the scrapping and replacement of the core barrel outer tubes themselves.
