BRINE AND BASE OIL SUPPLY SYSTEM WITH BACKUP FUNCTION AND BACK UP SUPPLY METHOD OF BRINE AND BASE OIL THEROF

摘要

Since the brine pump and the base oil pump have the same flow rate and head but differ only in the motor power according to the fluid characteristics, A brine having a backup function that allows the brine and base oil to be stably supplied for drilling even if one of the brine pump and the base oil pump fails, A base oil supply system, and a backup and supply method of brine and base oil. The brine and base oil supply system having the backup function according to the present invention includes a brine supply unit 110 for supplying brine from the brine tank 111 by the brine pump 112; A base oil supply unit 120 for supplying base oil from the base oil tank 121 to the base oil pump 122; A brine backup line (130) providing a path for supplying brine from the brine tank (111) to the base oil pump (122); And a base oil backup line 140 providing a path through which the base oil is supplied from the base oil tank 121 to the brine pump 112.
