摘要
An apparatus for protecting blowout preventers during well fracturing and/or stimulation procedures is disclosed. The apparatus includes a hollow spool with spaced-apart inner and outer sidewalk that define an annular cavity. A mandrel is reciprocally movable in the cavity. The apparatus is mounted above a BOP attached to a casing of the well before well stimulation procedures are begun. The mandrel is stroked down through the BOP to protect it from direct contact with the well stimulation fluids, especially abrasive proppants. The advantage is a simple, easy to operate apparatus for protecting BOPS which provides full access to the well casing with well servicing tools to facilitate well stimulation at moderate pressures.
