Saigao's spiral vane solid centralizers were developed in response to the need for better cementing in highly deviated and horizontal wells. These centralizers are designed to provide optimum flow-by area. A reduced flow-by area between the spiral blades produces a vortex motion of the fluids to increase fluid velocity with direction.
Saigao's spiral vane solid centralizers provide high impact, shock, and corrosion resistance, which are combined with their tensile and yield strength.
The 30° slope of the vane reduces drag and aids the casing in achieving TD.
Able to eliminate scraping, gouging, or digging into the formation, and consequently reduce balling between the vanes.
Being lightweight, these centralizers are helpful in reducing drag, and therefore are suitable for extended reach drilling (ERD), horizontal and highly deviated wells, where high drag is expected.
Suitable for wells where the rotating and reciprocation of casing is anticipated.
Able to withstand high wellbore temperatures while providing 100% horizontal stand-off.
Enable cement to be evenly distributed around the casing string.
Saigao's spiral vane solid centralizers are available in Steel Alloy (S-23), Zinc (S-25), and Aluminium (S-27)
Spiral vane steel alloy solid centralizers are constructed of a single-piece of fire and corrosion resistant steel alloy
Spiral vane zinc solid centralizers are constructed of non-sparking zinc alloy
Spiral vane aluminium solid centralizers are constructed of high-strength, corrosion-resistant cast aluminium alloy
Available in sizes 2 ⅞" to 13 ⅜”
