Downhole anchor with strengthened slips for well tool

A well tool, comprising:

• a downhole anchor including at least one outwardly extendable slip configured to grip a well surface, a slip retainer that circumferentially positions the slip in the anchor, and a spring that inwardly biases the slip relative to the slip retainer,
• in which the slip comprises longitudinally spaced apart grip structures, and a longitudinally extending beam which connects the grip structures to each other,
• in which the beam has a radial thickness which is greater than a lateral width of the beam,
• in which the spring surrounds the slip and the slip retainer.

A well tool, comprising:

• a central longitudinal axis;
• and
• a downhole anchor including at least one outwardly extendable slip configured to grip a well surface, the slip comprising longitudinally spaced apart grip structures, and a longitudinally extending beam which connects the grip structures to each other, and
• in which an area moment of inertia of the beam with respect to a lateral axis through a centroid of the beam is greater than an area moment of inertia of the beam with respect to a radial axis through the centroid of the beam, each of the lateral axis and the radial axis being perpendicular to the central longitudinal axis.
