Efficiently Remove Debris from Your Wellbore with Junk Sub A Must-Have for Drilling

__________________________________________________

Product Overview:

Junk Sub is a core tool in oilfield drilling and repair operations, dedicated to efficiently capture and remove heavy debris (such as carbide teeth, drill bit fragments, gadget parts, bearings, etc.) that cannot be discharged from the wellbore through conventional circulation. Ensure bottom cleaning and drill bit safety, significantly extend the life of the drill tool and reduce the risk of drilling. It uses high-strength alloy material and optimized fluid dynamic design, adapted to high pressure, high temperature and complex well conditions, and is a key equipment for improving drilling efficiency and operational reliability.

The Working Principle Of Junk Sub Produced And Sold By Our Company Huichi Petro:

In drilling operations, when it is necessary to salvage debris or falls from the hole, connect the Junk Sub to the drilling equipment and go down into the well. Then, through the operation of the drilling equipment, the garbage basket or other salvage tool connected to the lower end of the Junk Sub is sent downhole. When the garbage basket catches debris or falling objects, the Junk Sub and garbage basket are put out of the well through the lifting function of the drilling equipment to complete the salvage operation.

Core Functions And Features:

1. Efficient debris collection

• Eddy current deceleration design: Through the optimization of the outer contour structure and the annular space gap, the fluid flow rate is reduced and the vortex is formed, which promotes the natural settlement of heavy debris to the collection chamber, and the removal efficiency is increased by more than 40%.
• Modular filtration system: The multi-layer alloy filter can capture metal debris above 0.5mm, adapt to API standard casing (5″-13⅜″), and is compatible with straight, horizontal and large-slope well operations.

2. High pressure resistance and corrosion resistance

• It is made of chromium molybdenum steel or nickel-based alloy, which withstands extreme temperatures (-30℃ to 150℃), high pressure (up to 10,000psi) and acidic media environment, ensuring long-term downhole stability.

3. Flexible adaptability

• It can be quickly deployed with tools such as hydraulic disassembly and assembly (maximum torque of 300kN·m), continuous oil pipe (CTU), etc., supports multi-working operation, reduces the number of drilling and saves operating time by 30%.

4. Intelligent monitoring module (optional)

• o Built-in sensors monitor debris accumulation and tool status in real time, and reduce the risk of wellbore blockage through ground control system early warning.

Notes:

When using Junk Sub for salvage operations, you need to select appropriate salvage tools and operating methods according to the well condition and salvage needs to ensure the safety and success of the salvage operations. At the same time, you need to pay attention to the maintenance and maintenance of Junk Sub, and check the connection parts and wear conditions in a timely manner to extend its service life and maintain the best working condition.
