Problems solved by technology

Transmitting power, commands or information along a drill string or to and from a drill bit may prove challenging.
First, connections between drill pipe sections and drill bits are often made in wet and dirty environments where drilling mud and greases may be prevalent.
Contamination of connections by such materials may lead to faulty and unreliable communication.
Such a stab connector may not work properly, however, if the projection and receptacle are not continuously aligned.
Such threaded rotational connections may make keeping a stab connector aligned difficult.

Embodiment Construction

[0016]FIG. 1 shows an embodiment of a drilling operation comprising a drill bit 112 suspended from a derrick 113 by a drill string 114. The drill bit 112 may be rotated from the derrick 113 by a top drive, by a downhole motor disposed within the drill string 114, or by a combination of the two. As the drill bit 112 rotates it may engage and degrade an earthen formation 116 to form a borehole 111 therein. The drill bit 112 may be fed into the borehole 111 formed in the earthen formation 116 as the borehole 111 lengthens. Any of a variety of known downhole drill bits, such as a roller-cone bit or drag bit, may be used. Tools or other devices may be disposed at various locations along the drill string 114 to perform such tasks as controlling a rate of penetration of the drill bit or steering the drill bit towards an attractive destination. To gather information about the earthen formation 116 being drilled or the process of drilling as it progresses, any of a variety of sensors may be ...

Abstract

Connections between drill pipe sections and drill bits used for boring into the earth may comprise two elements threadably attachable one to another. A first element may comprise a rotor rotatable with respect to a stator. A second element may thread to the stator. As it does so, the second element may rotationally fix itself to the rotor allowing for connecting elements on the second element and the rotor to align. These connecting elements may remain aligned while the second element and rotor rotate with respect to the stator. Such alignment may allow for a connection to be kept clean and free from contamination in otherwise wet and dirty environments.

Description

BACKGROUND[0001]When exploring for or extracting subterranean resources such as oil, gas, or geothermal energy, it is common to form boreholes in the earth. Such boreholes are often formed by suspending a specialized drill bit from a derrick or offshore platform and rotating the drill bit to engage and degrade the earth as it turns. The drill bit may be suspended by coiled tubing or a series of drill pipe sections connected end-to-end forming a drill string, and rotated at the derrick / platform or by a downhole motor disposed towards an end of the drill string.[0002]In many situations, it may be desirable to pass power or commands down a drill string to control tools or other devices disposed along the drill string. Such commands may attempt to alter drilling parameters to increase a rate of penetration of the drill bit or to steer the drill bit towards an attractive destination. It may also be desirable to gather information about an earthen formation being drilled and pass it up a ...
