Pull-Push Type Packer

Our API-compliant Pull-Push Type Packer is a high-performance, mechanically actuated retrievable packer, purpose-built for onshore and offshore oil and gas well completion, zonal isolation, stimulation, workover, and intervention operations.

Unlike conventional packers that rely on tubing rotation, hydraulic pressure, or setting balls for actuation, this innovative packer achieves reliable setting and releasing exclusively through straight axial push and pull of the tubing string. This simplified design eliminates operational complexity, minimizes rig time, reduces downhole accident risks, and delivers consistent, long-lasting sealing performance in vertical, deviated, horizontal, and high-temperature high-pressure (HTHP) wellbores.

1.Tool-Free Push-Pull Actuation, No Rotation or Pressure Required : The packer is set via controlled downward axial push of the tubing string and released via steady upward pull, with no need for rotation, hydraulic pumping, or auxiliary setting tools. This eliminates torque loss and incomplete setting issues in deviated/horizontal wells, and cuts down operation time significantly.

2.Superior Bidirectional Sealing Performance :Equipped with high-performance, wear-resistant rubber seal elements (NBR/HNBR/FKM/Aflas optional), the packer delivers reliable upward and downward bidirectional sealing, withstanding cyclic pressure and temperature fluctuations without leakage. Standard models support up to 105 MPa (15000 PSI) working pressure and 204°C (400°F) working temperature, with custom ratings available for extreme conditions.

3.Fully Retrievable & Reusable Structure : The built-in automatic locking mechanism maintains stable anchoring and sealing during operation, while the pressure-balanced release system ensures smooth, jam-free retrieval with a single upward pull. Core structural components are engineered for repeated use, with only seal elements and wearing parts needing replacement between runs, greatly lowering customer operational costs.

4.Wide Compatibility & Customization Options ：Standard models fit API casing sizes from 2-3/8" (60.3mm) to 13-3/8" (339.7mm), with full compatibility with API standard tubing connections (EUE/NUE/BTC/LTC/STC) and premium custom threads. We offer custom material solutions for corrosive environments, including L80-13Cr, 316L stainless steel, Hastelloy, and Monel alloys, compliant with NACE MR0175/ISO 15156 for sour service wells with H2S/CO2.

5.Robust Design & Minimal Operational Risk ：Constructed from high-strength alloy steel with an integrated structure, the packer has no fragile small components, delivering excellent impact and wear resistance. The setting success rate reaches nearly 100%, with a low sticking risk during retrieval, effectively avoiding costly downhole fishing operations.

Q:What is the core difference between a Pull-Push Type Packer and conventional packers?

A:The key difference is the actuation method. Our Pull-Push Type Packer is set and released solely via axial push and pull of the tubing string, with no need for tubing rotation, hydraulic pressure, or setting balls. This makes it far easier to operate in deviated and horizontal wells, reduces rig time, and eliminates premature setting or failed releasing risks caused by complex actuation systems. Conventional rotation-set or hydraulic-set packers have more complex operations and higher failure rates in complex wellbores.

Q: Can this packer be used in horizontal and highly deviated wells?

A:Yes, absolutely. This packer is specifically optimized for horizontal, deviated, and directional wells. Since it does not require tubing rotation for setting or releasing, it avoids torque loss and incomplete setting issues that commonly affect rotation-set packers in long horizontal laterals. Its simple axial actuation ensures 100% reliable setting and releasing even in highly deviated wellbores.

Q:What casing sizes are available for the Pull-Push Type Packer?

A:We standardly produce this packer for API casing sizes ranging from 2-3/8" (60.3mm) to 13-3/8" (339.7mm). Custom sizes for non-standard casing are also available upon request. Please provide your casing size, weight, and steel grade when making an inquiry for a perfect fit.

Q: Can this packer be used in sour wells with high H2S and CO2 content?

A:Yes. For sour service wells, we offer custom anti-corrosion material options, including L80-13Cr, 316L stainless steel, Hastelloy, and Monel alloys for the packer body, along with corrosion-resistant FKM/Viton or Aflas seal elements. All sour service packers are manufactured in full compliance with NACE MR0175/ISO 15156 standards.

Q: Is the Pull-Push Type Packer retrievable and reusable?

A:Yes, it is a fully retrievable packer. It can be easily released and retrieved from the wellbore with a straight upward pull on the tubing string, with minimal sticking risk. The core structural components are designed for repeated use, and only the seal elements and wearing parts need to be replaced between runs, significantly reducing your operational costs.

Q: How long does it take to set and release the packer?

A:The setting and releasing process is extremely fast. Once at the target depth, the packer can be fully set within minutes with a simple downward push of the tubing string. Releasing is equally fast, requiring only a steady upward pull to unlock and retract the packer. This drastically reduces rig time compared to conventional packers with complex setting procedures.

Q: What tubing connections are compatible with this packer?

A:We offer standard API tubing connections including EUE, NUE, BTC, LTC, and STC. We also support custom premium tubing connections to match your existing tubing string. Please specify your required connection type when inquiring.

Q: Do you provide technical support for on-site operation?

A:Yes. We provide comprehensive technical support, including detailed operation manuals, step-by-step setting & releasing procedure guidelines, and 24/7 remote technical guidance. For large orders or special projects, we can also arrange on-site technical support from our experienced oilfield tool engineers.

Q: What is your lead time for production and delivery?

A:For standard sizes and specifications, our production lead time is typically 7-15 working days. For custom-sized, custom-material, or large-batch orders, the lead time will be confirmed based on your specific requirements. We support both sea freight and air freight for global delivery, with flexible shipping options to meet your project timeline.

Q: What testing and certifications are included with each packer?

A:Every packer undergoes full pre-delivery testing, including hydrostatic pressure testing, seal performance testing, and full-cycle setting & releasing function testing. We provide a complete set of certification documents, including API compliance certificates, material test reports (MTRs), factory inspection reports, and operating manuals. Custom third-party inspection (such as BV, SGS) is also available upon request.
