Casing running and drilling system
First Claim
1. A tubular gripping member for use with a top drive to handle a tubular, comprising:
- a body connectable to the top drive, wherein the body can be rotated by the top drive;
one or more slips coupled to the body, the one or more slips actuatable to engage the tubular; and
a first engaging member disposed on the one or more slips, the first engaging member having a first height extending from a face of the one or more slips; and
a second engaging member disposed on the one or more slips, the second engaging member having a second height extending from the face.

Abstract
A method and apparatus for holding and turning a tubular and string of tubulars, such as casing, for make-up and drilling with the tubulars are disclosed. The apparatus generally includes a spear and a clamping head, both of which are mounted to a top drive. The spear and the clamping head can be engaged to transmit torque therebetween from the top drive. In addition, an aspect of the invention provides variable height wickers positioned on slips to enable use of the slips with variable inner diameter (ID) and weight casing without deformation or rupture of the casing. Still further, a casing collar is also provided to provide reinforcement to the casing in the area of slip contact with the casing ID.

21. A tubular gripping member for use with a top drive to handle a tubular, comprising:
-
a body connectable to the top drive; one or more slips coupled to the body, the one or more slips actuatable to engage the tubular; and a first engaging member disposed on the one or more slips, the first engaging member having a first height extending from a face of the one or more slips; and a second engaging member disposed on the one or more slips, the second engaging member having a second height extending from the face, wherein a change in a load supported by the first engaging member causes the second engaging member to engage the tubular.
