PERFORATOR WITH A MECHANICAL DIVERSION TOOL AND RELATED METHODS

摘要

An apparatus can include a well treatment system that supplies a treatment fluid, a conveyance device and a well tool conveyed by the conveyance device. The well tool can include a perforator configured to form at least one hole in the wellbore tubular and a restrictor projecting from an outer surface of the well tool and adjacent to the perforator. A gap may separate the restrictor and the wellbore tubular. The well tool may also include a flow space that provides fluid communication between a location uphole of the restrictor and a location downhole of the restrictor. The flow space is sized to be restricted by particles in the treatment fluid. The restrictor at least restricts fluid flow through an annulus between the restrictor and the wellbore tubular, and the well tool diverts a substantial amount of the treatment fluid through an at least one hole formed by the perforator. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the general subject matter of the technical disclosure.

主权项

1. An apparatus for performing a downhole operation in a wellbore tubular, comprising:
a well treatment system that supplies a treatment fluid; a conveyance device; and a well tool conveyed by the conveyance device, the well tool including:
a perforator configured to form at least one hole in the wellbore tubular; anda restrictor projecting from an outer surface of the well tool and adjacent to the perforator, wherein a gap separates the restrictor and the wellbore tubular, the restrictor at least restricting fluid flow between the restrictor and the wellbore tubular, and the restrictor diverting a substantial amount of the treatment fluid through the at least one hole formed by the perforator.
