Drilling Rods TRIZ Cases

A release tool uses a trigger mechanism to send an electrical signal that detonates a separation bolt.

Segmenting the main bore into two independently controlled mini wells reduces rig-up and rig-down time while maintaining pressure control.

A drill string element uses a unique hole configuration to protect internal cables.

Automated riser handling system aligns and locks tubular sections using sensors and actuators, reducing operator exposure to repetitive motion injuries.

A flexible riser end fitting separates sealing and anchoring zones to enable assembly without bending tensile armour.

Segmenting the power cable deployment from the pump assembly eliminates bending stresses and crushing damage during well installation.

Vacuum pumps remove trapped air from aquifers to increase recharge rates, addressing groundwater depletion and energy-intensive desalination costs.

Segmented dissolvable guards shield downhole connectors from debris, then dissolve to clear mating surfaces without manual removal.

Sensors verify pin engagement before allowing coiled tubing injector tilt, preventing ejection during transport.

Hydraulic heave compensation on a mobile working deck eliminates riser installation time while maintaining operational stability.

An array of inner axial vanes intercepts particulate laden fluid vortices, reducing pipe surface wear during high-pressure fracturing operations.

Automatic stabilization member contacts outer tubular to restrict lateral movement and vibration during cutting.

Sequential cone expansion eliminates unexpanded portions that require complex removal tools, reducing wellbore preparation time.

Elastic gripping elements with hard inserts prevent slippage on irregular surfaces during torque transmission.

Sliding sleeve shifts positions to adjust flow settings, preventing premature water or gas breakthrough in well completion systems.

A drilling device with a telescopic auger and hydraulic lifting drive enables axial displacement of the worm gear within a shaft.

Segmenting the tubular into a ground-down zone protects bow-spring ribs from damage during passage through tight wellbore restrictions.

A flexible guide pipe deforms around bends in an outer pipe to advance a conduit toward a lateral well access passage.

Independent shuttle arms with hydraulic actuators and sensors manage velocity adjustments for precise alignment.

A segmented containment chute with sealing profiles and a drain spout captures leaking drilling fluid, preventing hazardous spills on the rig floor.

Ballast pumps adjust buoyancy in a subsea storage unit, ensuring stable cargo placement despite harsh offshore conditions.

A seal stem anchor assembly uses a helical spring to deploy slips and support heavy axial loads in well operations.

An adaptor apparatus uses slots and fluid channels to generate a vortex flow that prevents particulates from settling on the plunger.

A rotatable bore selector switches a monobore riser between main and annulus bores in subsea wells.

A wellsite connection assembly uses a floating cartridge to movably position male and female connectors relative to each other.

Locking connectors join detachable drill rod sections, enabling targeted replacement of worn parts to reduce costs and safety risks in confined mines.

Ballast module offsets buoyancy in sag bend portion to prevent collision from marine growth weight changes.
