Product Introduction

The 2.5 inch SV Swab Cup is a specialized fluid-recovery tool engineered specifically for wellbore environments with a high sand-to-fluid ratio. In operations where suspended solids, silt, or proppants are present, standard rigid cups often suffer from premature tearing or seal failure. The SV style addresses this challenge with a series of flexible, multi-ribbed lips that can deflect around abrasive particulates during the downward trip and establish a 360-degree seal during the lift. This fluid-actuated design ensures that even in the most abrasive conditions, fluid recovery remains efficient while protecting the tool string from excessive wear.

Technical Specifications

Other Available types of Swab cups:

TA style: TA is a medium load Swab Cup built around a steel or aluminum bushing for use in most sizes of tubing or drill pipe. When under load, it will compress to form a solid rubber mass for maximum lifting capacity and minimum wear. Manufactured from a newly developed rubber compound, these cups provide our customers with a high quality North American product. Our special Frac Fluid compound is developed for the ultimate in durability and performance. These Frac Swab Cups are designed to perform under the toughest conditions.

MV style: Shanghai Qinuo offers the popular Guiberson* profile MV Swab Cup in both nitrile and frac fluid rubber compound. The cup has either an aluminum or steel bushing with multiple upturned lips which allows it to pass through tight spots and control the amount of load. It is very efficient in fluid with suspended sand.

V style: Shanghai Qinuo carries the V Series Swab Cup in a light duty and heavy duty all rubber cup that is suited for use in fluids with high concentrations of suspended sand. The upturned lips pass easily through tight spots and will invert to dump excessive loads. The number of cups used will vary with conditions.

Key Features & Advantages

1. Sand-Resistant Flexible Lips: The SV profile features flexible ribs that allow sand and small solids to pass through the tool during descent, preventing the tool from becoming stuck or "sanded in" within the tubing.

2. Fluid-Actuated Expansion: The weight of the fluid column triggers the expansion of the flexible sleeve. This ensures a positive seal against the tubing wall that is proportionate to the load, reducing unnecessary friction in lower-fluid scenarios.

3. High-Modulus Elastomer Compound: Molded from premium-grade Nitrile, these cups offer superior tensile strength and abrasion resistance, maintaining their sealing edge even after multiple runs through rough or sandy sections.

4. Versatile Interference Fit: The flexible nature of the SV lips allows them to conform to tubing irregularities, such as internal scale buildup or minor pitting, where more rigid cups would lose their seal.

5. Efficient Debris Bypassing: By allowing solids to migrate away from the primary sealing surface during the stroke, the SV design minimizes the "grinding" effect that typically destroys standard swab cups.

FAQ

Question: What makes the SV cup the best for high sand ratios?
Answer: Its multi-lip, flexible design allows it to navigate particulates that would cut or jam a single-lip rigid cup. The lips "give" slightly under the pressure of a solid particle while the rest of the sleeve maintains the seal.

Question: Will these cups fit my standard 2.5 inch mandrel?
Answer: Yes, our 2.5 inch SV cups are precision-molded to fit all industry-standard API swab mandrels used in 2.5 inch nominal tubing.
