straight Vane Solid Body Rigid Aluminum Centralizer
Straight/Spiral Vane Aluminum Solid Centralizer
› Made of high tensile, solid, cast aluminum for shock, impact and corrosion resistance.
› Used in areas where a good primary cementing job is required, including deviated and horizontal wells, liner overlaps and shoe joints.
› Suitable for either cased or open hole.
› Spiral vanes fully overlap to give 100% wellbore coverage and increase annular turbulence to improve wellbore cleanout.
› Vane ends are beveled 30 degree relative to the casing centerline to provide excellent lead into restrictions and reduced drag when running in the wellbore. Besides, it keeps running forces at a minimum.
› Wide vanes distribute load from the casing string into the wellbore without gouging.
› Standard size is 4-1/2" to 20". Any special sizes or combinations can be customized on request.
Applications
The solid rigid centralizer ensure positive centering in deviated or horizontal holes. It can provide mechanism to centralize the casing in the wellbore and allow uniform cement flow around the casing by reducing the effects of channeling and protect the casing at all points.
But since the centralizers are smaller than the wellbore, they will not provide a good centralization as the bow spring centralizers do in vertical wells.
