Abstract
A connector is presented for tubing conveyed perforating guns which facilitates connection or disconnection between guns without the need for rotation. A latching mechanism is disclosed which latches by setting down weight and unlatches by an actuating ram camming the latch out of a window. The connectors are configured so that they are sealed internally and have an external profile for interengagement with a seal ram for support and sealing around the outer periphery. Accordingly, a live well can be isolated using a seal ram around a fired gun because the internal passages through the gun are sealed off by virtue of seals around a hammer piston. The connectors are configured so that an upper gun creates the pressure required to set off the gun below. The connectors are also configured such that when a lower gun is supported by a seal ram, an emergency shear zone is presented opposite a shear ram to ensure that if an emergency well shutdown is required that the shear ram does not have to cut through a section of the gun which contains explosives.
