CAST SLIP WITH PRESET CARBIDE BUTTONS |
摘要 |
A slip for support of a downhole tool is cast with inserts positioned in the mold. The inserts can have a unique shape to allow them to be retained in the cast slip while having the proper position relative to each other and proper extension and orientation. A placement tool is envisioned to allow sets of inserts to be initially placed in the mold at one time and released from the tool.
