Modular connector and method
First Claim
1. An apparatus, comprising:
- a modular apparatus configured for conveyance on a drill string in a wellbore extending into a subterranean formation and comprising;
a first module comprising a first collar at least partially defining an exterior of a modular tool for use in the subterranean formation, wherein the first collar comprises a first engagement mechanism at a first end of the first collar, a second engagement mechanism at a second end of the first collar, and a first fluid passageway configured to pass drilling fluid therethrough;
a second module comprising a second collar at least partially defining an exterior of the tool, wherein the second collar comprises a third engagement mechanism at a first end of the second collar, a fourth engagement mechanism at a second end of the second collar, and a second fluid passageway configured to pass drilling fluid therethrough, wherein the third engagement mechanism is configured to engage the second end of the first collar;
at least one connector configured to connect the first and second modules, including;
connecting a first auxiliary fluid line of the first module and a second auxiliary fluid line of the second module; and
connecting a first wire of the first module and a second wire of the second module to transmit power and/or data between the first module and the second module; and
means for coupling a drill bit to the end of the modular apparatus, wherein the drill bit coupling means is configured to receive drilling fluid through the first and second fluid passageways;
wherein the engagement mechanisms of the first and the second modules comprise opposing threaded portions, and wherein the first module is a probe module comprising an assembly configured to isolate a portion of a wall of the wellbore.

Abstract
A modular tool for use in subterranean formations includes a first module, a second module and one or more connectors for connecting the first and second modules. In particular, the first module includes a first collar that at least partially defines an exterior of the tool and that includes a first engagement mechanism at a first end of the collar and a second engagement mechanism at a second end of the collar. The first module also includes a fluid passageway for passing drilling fluid therethrough. The second module has a similar configuration as includes similar architecture. The one or more connectors facilitate the connection of at least one flowline fluidly connected to an exterior of the tool, and an electrical pathway for transmitting power and/or data between the modules.
