ACT Drillable Cement Retainers Wireline Set |
 | |
The ACT Model BKR Premium Cement Retainer (W/L) is a wireline set, high
pressure retainer constructed of drillable cast-iron that uses Bolt, Elder or Baker K-1
type setting sleeves and tension mandrels. It can be set on any Baker type wireline
pressure setting tool or pipe/coil tubing with an ACT Hydraulic Setting Tool. When
set, opposing slips are located above and below the rubber packing elements. The
packing elements are contained by rocker action back-up rings that eliminate
extrusion of the elements at high temperatures and pressures. A one way ratchet
lock ring retains the setting force applied to the opposing slips and rubber to maintain
a pressure tight seal. One-piece slips keep the retainer securely set in premium
grade casings including P-110. The slip wickers are sharp and hardened to the
wicker depth only allowing the slip to grip the casing wall while maintaining a soft
cast-iron inside for easier drilling. It features a pressure balanced two way valve
located in the bottom shoe. The operator controls the two way valve from the surface
to hold the final squeeze pressure under the retainer or test tubing or keep
hydrostatic pressure off the squeeze. Straight pick up closes the valve and set down
weight opens the valve. This retainer is ideal for where squeeze cementing
operations are being performed. Optional packing systems of Viton or Aflas are
available on special order. Special application tools can be custom designed to fit
your specific needs. Available in 4-1/2" thru 13-3/8" casing sizes. After the ACT BKR Cement Retainer is set on wireline a BKR Seal Unit is required to perform the squeeze job. These seal units are available in two types, a locator seal unit or a snap latch seal unit. The seal unit is installed on the bottom of the workstring to control the two way valve in the set retainer.
