AI Technical Summary

Benefits of technology

The present invention provides a universal coupling system for drilling rigs with fewer components and simplified components to save time and money. The system includes a wedge rotor adaptor and two double wedges that can be connected together to form a drill string. The double wedges can be connected with a wedge bearing adaptor for added stability. The system is designed to be easy to manufacture, use, and replace.

Problems solved by technology

An oversized wellbore may cause efficiency issues during drilling as the drill bit takes more power to remove more material and / or may cause issues during casing as more cement may be needed to properly set the casing.

Embodiment Construction

[0039]Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this disclosure. The Detailed Description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims. Additionally, any combination of features shown in the various figures can be used to create additional embodiments of the present invention. Thus, dimensions, aspects, and features of one embodiment can be combined with dimensions, aspects, and features of another embodiment to create the claimed embodiment.

Abstract

A universal coupling system for a drill string is provided. The system comprises a double wedge box having a first box connection opposite a second box connection. The system also comprises a first double wedge and a second double wedge each releasably coupled to the double wedge box and each having a first wedge protrusion offset from a second wedge protrusion. The first wedge protrusion of each of the first double wedge and the second double wedge are received in the first box connection and the second box connection, respectively. The system also includes a first adaptor and a second adaptor each having a box connection opposite a pin connection. Each box connection of the first adaptor and the second adaptor receives the second wedge protrusion of each of the first and the second double wedges.

Description

FIELD OF THE INVENTION[0001]Embodiments of the present invention generally relate to drilling with a universal coupling system, and more specifically a universal coupling system designed to allow for a universal connection between a power source and a bearing pack of a drill string or between two power sources (e.g., a dual power section) using a reduced amount of components.BACKGROUND OF THE INVENTION[0002]Universal coupling systems are known in the drilling arts. In particular, universal coupling systems are used to convert eccentric motion of a power source (e.g., a rotor and stator used in a mud motor) to circular motion for rotating a drill bit at a bottom of a drill string. The universal coupling system further transmits torque between the power source and the drill bit and thus must be capable of handling large amounts of torque.[0003]Conventional coupling systems typically involve many complex components that are prone to failure and may require replacement of the entire sys...
