| 发明名称 | Tubular anchoring system and method | ||
| 摘要 | A tubular anchoring system includes a frustoconical member having a first frustoconical portion and a second frustoconical portion. The first frustoconical portion is tapered in a direction opposing a direction of taper of the second frustoconical portion and slips in operable communication with the first frustoconical portion are radially expandable in response to longitudinal movement of the first frustoconical portion relative to the slips. A seal in operable communication with the second frustoconical portion is radially expandable in response to longitudinal movement of the second frustoconical portion relative to the seal, and a seat having a surface configured to be sealingly engagable with a plug runnable thereagainst. | ||

| 主权项 | 1. A tubular anchoring system comprising a frustoconical member having a first frustoconical portion and a second frustoconical portion, the first frustoconical portion being tapered in a direction opposing a direction of taper of the second frustoconical portion; slips in operable communication with the first frustoconical portion being radially expandable in response to longitudinal movement of the first frustoconical portion relative to the slips; a seal in operable communication with the second frustoconical portion being radially expandable in response to longitudinal movement of the second frustoconical portion relative to the seal; and a seat having a surface configured to be sealingly engagable with a plug runnable thereagainst sufficient to support pressures built against a seated plug to allow borehole treatment operations. | ||
