Coring Apparatus And Methods To Use The Same |
| 摘要 |
A coring bit assembly for conveyance via wireline or drillstring in a wellbore extending into a subterranean formation. The coring bit assembly includes a coring shaft and a thrust ring coupled to an end of the coring shaft. A static sleeve is disposed inside the coring shaft and having a flange coupled to the thrust ring to space the static sleeve from the coring shaft to form a drilling fluid passageway between the coring shaft and the static sleeve. An axial fluid pump is disposed on the coring shaft to engage with the static sleeve to drive drilling fluid through the drilling fluid passageway formation. |
