Solution Overview

Problem

Current drilling technologies require multiple drill bit designs for different drilling applications, such as vertical, horizontal, and lateral wells, leading to inefficiencies and increased costs due to the need for various drill bits and inventory management.

Innovation Solution

A drill bit with an adjustable gauge system, featuring machined connections and rings that can be added or removed to modify the gauge length and angle, allowing the drill bit to adapt to different wellbore characteristics and drilling requirements, thereby enabling operation in various formations without the need for multiple drill bit designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple drill bit designs are used for different drilling applications, then the drill bit can adapt to various wellbore characteristics, but the device complexity and inventory requirements increase

Engineering Contradiction:
Improveadaptability to wellbore characteristicsVSAvoidnumber of drill bit designs
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The drill bit is designed with a universal gauge system that can be adjusted to perform multiple drilling functions. The gauge includes adjustable components (such as movable gauge pads or extendable gauge sections) that can be positioned at different lengths and angles to accommodate vertical, horizontal, and lateral wellbores, allowing a single drill bit design to replace multiple specialized designs

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The gauge system incorporates dynamic, adjustable elements rather than fixed components. The gauge length and angle can be modified during or before drilling operations to match the specific wellbore characteristics, enabling the drill bit to adapt its geometry dynamically to different drilling applications without requiring multiple static designs

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple drill bit designs are maintained in inventory, then all drilling applications can be covered, but the loss of substance and storage requirements increase

Engineering Contradiction:
Improvecoverage of drilling applicationsVSAvoidwaste from multiple drill bits
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

Instead of discarding entire drill bits when gauge specifications need to change, the invention allows for selective adjustment or replacement of only the gauge components. The main drill bit body and cutting elements can be retained and reused, while only the adjustable gauge sections are modified or repositioned, significantly reducing material waste

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The drill bit's effective geometry is changed by adjusting parameters of the gauge system (length, angle, position) rather than changing the entire drill bit. This parameter adjustment capability allows the same physical drill bit to serve multiple applications, reducing the need to manufacture and dispose of multiple drill bits with different fixed geometries

Inventive Principle:
Principle #35Parameter changes

AI summary

A drilling tool for drilling a wellbore in a formation includes a drill bit including a plurality of blades and a machined connection disposed on the drill bit. Each of the plurality of blades includes a gauge having a length and an angle. The machined connection is configured to allow attachment of a plurality of machined rings to the plurality of blades. The plurality of machined rings are configured to form the length and the angle of each gauge based on number and type of each machined ring attached. The drill bit is configured to operate in different formations based on the gauge of each of the plurality of blades. The drilling tool is redesigned by removal or addition of one or more of the machined rings based at least in part on a modified length and a modified angle configured in view of a characteristic of the wellbore.
