Drilling Rods TRIZ Cases
- Pipe Gripping Assembly Power Screw Actuator
A pipe gripping assembly uses a motor-driven power screw to move slips along a tapered mandrel for secure pipe handling.
- Reversible Rod Tong Assembly with Rotatable Inner Ring
Rotating the outer ring pivots jaws via rollers to tighten or loosen connections, eliminating manual power disconnection steps.
- Jointed Pipe Injector Trigger Mechanism for Snubbing Operations
Trigger mechanism manages gripper block interactions with varying diameter profiles in rotating jointed pipe injectors to reduce friction and buckling risks.
- Downhole Safety Joint Circumferential Stress Reliefs
Circumferential stress reliefs absorb side loads while flow channels prevent hydraulic locking in deviated wellbores.
- Robotic System With EX-Certified Chamber for Subterranean Tubular Handling
An EX-certified chamber isolates electrical components in a robotic clamping system, reducing explosion risks during subterranean tubular handling.
- Hydraulic Workover Unit Dynamic Sealing for Live Well Operations
Elastomeric blowout preventers seal around irregular ESP strings during telescoping motion, eliminating kill fluids and preventing formation damage.
- Downhole Swivel Joint Resilient Latch for High Drag Retention
A resiliently deformable latch retains a downhole swivel joint in its unactivated configuration, preventing unintended activation during high wellbore drag.
- Gear Nut Adjustment Assembly for Automated Pipe Diameter Adaptation
Motor-driven gear nut assembly rotates ring gears to automatically adjust wrench jaws, eliminating manual pipe diameter changes.
- Sliding Sleeve Valve for Compact Fracturing Manifold Isolation
A sliding sleeve valve establishes fluid communication between intersecting bores to manage flow paths in hydraulic fracturing systems.
- Wellbore Milling and Suction Apparatus for Underbalanced Clearing
A milling and suction apparatus clears wellbore obstructions using a venturi component to create underbalanced pressure.
- Threaded Joint Incomplete Threads External Pressure Sealing
Incomplete threads with reduced height allow radial box contraction, amplifying contact interfacial pressure to resolve external pressure sealing trade-offs.
- Floating Apparatus Bonding Material Micro-Annulus Seal
A floating apparatus uses a bonding material to create a resilient seal between the valve housing and cementitious material.
- Multi-Attribute Acoustic Characterization of Multiple Casing Strings
Analyzing instantaneous frequency, phase, and amplitude characterizes material densities at interfaces to identify fluid flow paths in complex wellbores.
- Redeployable Subsea Manifold Riser System
A subsea manifold module uses a marine riser as both running and retrieval tool for relocation.
- Automatic Driller Brake Handle Elastic Feedback Control
Elastic mechanisms return a manual brake handle to a set point for precise control of a rotating primary mover.
