摘要 |
A coring bit for use on a coring tool for extracting a sample of subterranean formation from a well bore includes a bit body having a cavity, wherein a throat portion of the cavity extends into the bit body from a face of the bit body. The coring bit includes a sleeve disposed within the cavity of the bit body, the sleeve configured to separate a face discharge channel and a throat discharge channel. The face discharge channel is located radially outward of the sleeve and the throat discharge channel is located radially inward of the sleeve.
