Completion and Cementing Tool Solutions

Successful well completion requires equipment that can perform reliably under challenging downhole conditions while providing the versatility needed for complex well architectures. Yantai Sanmon Machinery Equipments Co., Ltd. delivers a complete portfolio of completion and Cementing Tools that meet the most stringent industry standards and operator specifications.

1 Production and Service Packers

Packers are the cornerstone of zonal isolation in completed wells, and SANMON offers a comprehensive range to cover every completion scenario. Our mechanical production packers provide reliable single-string isolation with proven slip-and-cone anchoring systems rated for differential pressures up to 10,000 PSI.

For applications requiring Tubing movement or future retrieval, our retrievable seal bore packers offer a polished bore receptacle that accommodates tubing expansion and contraction while maintaining a gas-tight seal. Available in sizes from 2-3/8" through 9-5/8", these packers can be configured with various elastomer compounds for standard, high-temperature, and sour service environments.

The hydraulic-set retrievable packer series eliminates the need for tubing manipulation during setting, making them ideal for deviated and horizontal wellbores where mechanical setting forces are difficult to transmit. Our dual-bore hydraulic packers accommodate parallel tubing strings with independent sealing in each bore, supporting complex dual-zone completion designs.

For testing and well intervention operations, the RTTS (Retrievable Test-Treat-Squeeze) mechanical slip packer provides a robust solution for drill stem testing (DST), stimulation treatments, and temporary zonal isolation. The RTTS packer features bidirectional slips and a large bypass area for rapid running and retrieval in cased hole applications.

2 Cementing Equipment

Effective cementing is critical for achieving hydraulic isolation between formations and protecting casing from corrosive fluids. SANMON supplies a complete line of cementing tools designed to ensure consistent cement placement and reliable primary cement jobs.

Our cement heads accommodate single-plug and double-plug cementing operations, with swivel connections that allow rotation during cement displacement for improved mud removal. The Drill Pipe cementing head design incorporates an integral dart release mechanism for subsea applications, providing positive indication of plug release at the rig floor.

Cementing plugs in both top and bottom configurations are manufactured from drillable materials that can be easily milled out after the cement has set. Each plug is dimensionally matched to the specific casing or liner weight to ensure effective wiping of the casing ID during cement displacement.

3 Casing Centralizers and Accessories

Proper casing centralization is essential for achieving uniform cement coverage around the casing circumference. SANMON's API 10D certified centralizer range includes bow spring centralizers, rigid-blade centralizers, and low-friction spring designs engineered for various wellbore geometries.

Our bow spring centralizers feature high-restoring-force spring designs manufactured from heat-treated alloy steel, providing consistent standoff even in irregular wellbores. Slip-on and hinged configurations accommodate various installation methods. Special anti-corrosion spring centralizers with protective coatings are available for offshore saltwater injection wells and other corrosive service applications.

Completing the casing accessories line, we supply float collars, float shoes, stage cementing collars, and guide shoes manufactured to API 10D and 5CT specifications. Each accessory is engineered to integrate seamlessly with the selected casing grade and weight, ensuring reliable performance during running and cementing operations.

4 Shaped Charges and Perforating

For perforating operations, SANMON supplies steel-case shaped charges with optimized charge geometry for deep penetration or large-hole perforating requirements. Our charges are available in sizes from 3-3/8" through 7" with loading configurations matched to your reservoir characteristics and completion objectives.
