Flushing TRIZ Cases
- Drilling Waste Weight Material Recovery Process
Recover high-purity weight material from drilling waste using low temperature thermal cleaning and specific gravity segregation.
- Choke Trim Assembly Slip Fit Alignment
A choke trim assembly uses a slip fit between a clamp ring and trim carrier to center the donut-shaped trim.
- Subterranean Coring Assembly Flow Regulation
Movable flow regulating device adjusts position within cavity based on fluid characteristics to transition between operational modes.
- Submarine Wire-Line Coring Drill Rig Process for Sediment Extraction
Sediment core-boring drilling process uses pressure-suction mode with thin-walled annular cutting blade to extract seabed samples.
- Dynamic Sampling While Drilling Simulation Engine
Simulation engine optimizes drilling and sampling plans using real-time feedback, resolving empirical method limitations that reduce sampling efficiency.
- Automated Choke Control for Safe Pressurized Mud Cap Drilling
A feedback control system automatically adjusts surface backpressure chokes to prevent gas influx and fluid loss in fractured reservoirs.
- Temporary Seal for Wellbore Casing with Segmented Breakdown
Segmented temporary seal breaks at pressure thresholds, enabling cement placement and debris removal while maintaining casing integrity.
- Real-Time Cuttings Transport Ratio Calculation in Drilling
Calculates cuttings transport ratio via effective mud weight and slip velocity to prevent stuck pipes and uneven drilling rates.
- Flow Control Tool Valve Element Position Indication
A flow control tool valve element generates distinct pressure spikes to indicate its internal position.
- Emergency Valve Assembly Rotating Stopper Shear Mechanism
Explosive drive rotates a stopper to shear drilling lines, preventing blow-outs when conventional BOPs fail at deep sea depths.
- Concentric Drillstring Subsea Pump Pressure Control
A concentric drillstring and subsea pump manage wellbore fluid pressure by controlling hydrostatic column height.
