Abstract:

A device for use in setting a liner in a well casing is disclosed which utilizes a setting sleeve connected to the top of the liner, which setting sleeve has an annular sealing flange located on the outer surface thereof. A tubular flaring sleeve fits over the outer diameter of the top of the setting sleeve, and a beveled end on the bottom of the flaring sleeve is used to flare the annular sealing flange radially outwardly in a uniform manner since the beveled end will always remain aligned with the annular sealing flange. In addition, when the setting device and liner are being lowered into the well casing, the flaring sleeve is locked in an upward position on the setting sleeve preventing premature flaring of the annular sealing flange prior to installation of the liner at the bottom of the well.
