SYX-A Hydraulic Liner Hanger

As one of the oil equipment suppliers, Saigao Groupspecializing in design, research, and development, processing, and manufacturing. sales and export of machinery equipment, with leading products comprising various kinds of mudpumps, down-hole motors, any kinds of screen pipes, cementing tools as well as any kinds ofwellhead equipment.

The SYX-A is hydraulic liner hangerfeatures double cones and double-row slips, set by applying pressure through the run-in string. A setting ball is circulated or dropped to a ball seat built into the landing collar. Applied pressure acts on the internal piston and moves slips up the cone to the set position.

Features of SYX-A Hydraulic Liner Hange

lThe SYX-A hydraulic liner hanger is to be set hydraulically, which is designed for in all types of wells.

lWorking with SQ setting-set carrier, the SYX-A is suitable for applications in horizontal or highly-deviated wells.

lThe piston sealing element is made of nitrile/fluorine rubber for higher pressure and temperature ratings.

lMain parts are fabricated with high-strength alloy steel providing high burst/collapse resistance.

lThe structure is suitable for hanging long heavy liner in deep wells. Liner weight is distributed onto the internal wall of the previous casing more evenly.

lThe setting tool can be easily released just by slacking off certain weight and using right hand rotation.

lRetrievable Pack-off Bushing can be retrieved with setting tool, eliminating drill-out.

Application of SYX-A Hydraulic Liner Hange

lThe rotating liner hangermainly realizes tail pipe suspension through hydraulic transmission. It is widely used in oil and gas wells, technical tail pipe of salt brine wells and geothermal wells and production tail pipe cementing. In the following cases, the tail pipe hanger is used for cementing:

lIt is possible to save a lot of casing and cost for deep wells and evaluation wells.

lCompletion of the casing head and surface casing load

lImprove long-term cement cementing operations to prevent low-pressure leakage

lQuickly and easily seal the open hole section and the old well deepening cementing

lProvide flexible completion methods and safer cementing operations

lIn the Rock salt well section, the tail pipe is used to enhance the sealing strength of the rock salt section.

lSeal the damaged section of the upper casing (corrosion, fracture)
