Cleaning galling after ***bit shankage***

Weight–on-bit control in deep holes is always a challenge. Get it right
and the risk of bit shanking is small. Get it too heavy or too light and
the risk of ***bit shankage*** and losing a bit head in the hole is high. Cen-
ter Rock offers an innovative bit retainer system for applications where
the risk of bit shanking needs to be addressed. The retainer system
provides a secondary means for retaining the bit head to the hammer,
should the bit shank through the splines

quebra no pescoço da broca


Explanation:
Quando se tem uma falta de peso sobre o martelo é comum ter uma ruptura do pescoço do bit e uma pressão elevada causa desgaste acelerado.

vibração da broca


Explanation:
Vibrações
Através da observação das oscilações das medidas na
superfície de torque e rotação da coluna de perfuração é
possível se detectar os possíveis tipos de vibração. O peso
sobre a broca também é um fator que influencia na detecção do
tipo de vibração que esteja ocorrendo, ou seja, um elevado peso
sobre a broca favorece o aparecimento do tipo de vibração
torcional stick slip (broca para de girar por alguns instantes e a
energia acumulada ao ser liberada acelera o BHA), já um baixo
peso sobre a broca favorece a ocorrência do tipo de vibração bit
bounce (vibrações axiais que induzem na broca um movimento
intermitente entre o contato e a perda de contato com o fundo
do poço) e whirl (vibração lateral).
