Product Description

The Top Drive WASHPIPE ASSEMBLY stands as the pivotal element within the Top Drive drilling apparatus, ingeniously positioned between the SAWIVAL and drill string. Its purpose? To expertly craft a rotating, sealed conduit for high-pressure drilling fluids. At its heart lies a robust, corrosion-resistant alloy steel pipe, intricately engineered with a cutting-edge multi-stage mechanical sealing system. This marvel ensures a dynamic seal is preserved seamlessly as the drill bit whirls.s.

Function: 1. Drilling fluid circulation channel: As an indispensable component for high-pressure mud conveyance, it efficiently ensures the circulation of drilling fluid.
2. Safety protection function: In tandem with IBOP, it swiftly seals the flow channel to manage well emergencies effectively.
3. Process optimization support: Its modular design allows for rapid replacements, maintaining an approximate maintenance cycle of 500 hours.

4. Dynamic sealing center: Incorporating a sophisticated multi-stage sealing structure (O-ring + floppy disk) adeptly prevents fluid leaks. The inventive pre-tightening design permits real-time monitoring of seal pressure, heightening emergency response capability.



After three generations of technological evolution;

First generation (Traditional Wash Pipe Assembly)
Featured a carbon steel matrix combined with a carbide bushing, depending on a multi-layer packing seal necessitating frequent grease upkeep (every 50 hours).
Typical issue: Seal failure, resulting in mud leakage with an average lifespan limited to 200-300 hours.

Second generation (Adjustable Washpipe Assembly)
Utilized Utex packing from the USA, paired with a domestic supersonic tungsten carbide flushing pipe, significantly boosting longevity in high-pressure, oil-based mud settings.

Third generation (Mechanical Washpipe Assembly)
Innovations: Eliminating the independent bushing structure, requiring only the replacement of dynamic and static rings during maintenance. This advancement curtails daily maintenance downtime, minimizing operational disruptions.


 

 

 

Mechanical Washpipe Assembly;

A pioneering mechanical seal washpipe assembly comprises an upper connecting nut, static ring, dynamic ring, dynamic ring anti-rotation pin, and lower connecting nut. Its design offers prolonged service life, straightforward maintenance, and reliable operation, necessitating just the exchange of dynamic and static rings. Under standard operations, the washpipe seal's lifespan extends, allowing continuous operation for up to 1700 hours. It withstands pressure levels of 5000PSI and 7500PSI. Compatible with NOV and various domestic Top Drive models, its advantages shine under conditions with pressures up to 5000PSI and temperatures over 100°C. Maintenance-free during its regular service life, it reduces downtime for daily disc root washpipe maintenance, thus enhancing operational efficiency.

Daily maintenance:

1. Lubrication management: Ensure the addition of grease to critical points of the equipment daily (2-4 applications per location).
2. Leakage check: Carefully monitor for any signs of mud leakage at the crucial connection point between the flushing pipe and the main shaft. Should the leakage exceed a critical threshold of 5 drops per minute, it is imperative to halt the machine operations immediately and proceed with replacing the seal to ensure optimal performance and safety.
3. Fastener inspection: Diligently inspect the flushing pipe fixing bolts and anti-loosening gaskets on a daily basis. Ensure that the torque adheres to the established standards, safeguarding the assembly from any potential faults.
Monthly: Disassemble and inspect the flushing pipe assembly with precision. Replace any worn packing to maintain optimal functionality. Should the hardness of the O-ring decrease by more than 15%, replace it promptly to sustain the assembly's integrity.
Seasonally: Flush the hydraulic system thoroughly to eliminate impurities from the sealing chamber. Achieve an oil contamination level of NAS-8 or below to ensure the system operates at peak efficiency.




Key technological breakthroughs:

1. Sealing revolution: Transitioning from traditional O-rings to advanced hydraulic compensation seals and cutting-edge magnetic fluid seals has reduced the leakage rate by an astounding 99%, marking a new era in sealing technology.
2. Material upgrade: The introduction of tungsten carbide-based composite materials has enhanced impact resistance by a remarkable 200%. Additionally, the application of a surface nano-coating effectively minimizes mud erosion, providing superior durability.
3. Intelligent integration: Seamlessly integrated with the Top Drive control system, our technology dynamically matches torque and seal pressure to optimize performance. This innovation is exemplified by models such as the VARCO TDS-11SA.



Industry application value:

Efficiency improvement: Our revolutionary third-generation flushing pipe dramatically extends the replacement cycle from a mere 3 days to an impressive 30 days, significantly reducing non-operating time and boosting overall efficiency.
Safety enhancement: Equipped with a real-time monitoring function, our system can alert operators of potential seal failures up to 48 hours in advance, effectively preventing well control accidents and enhancing operational safety.
Cost optimization: The extended lifespan of our flushing pipes reduces consumption for single wells by a substantial 60%, resulting in significant cost savings and enhanced economic efficiency.
