Abstract

Ένα σύστημα διάτρησης με υδραυλικό σφυροτρύπανο διπλού κυκλώματος (10) έχει ένα υδραυλικό σφυρί (12) το οποίο είναι συζευγμένο με μία διατρητική στήλη (14). Το σύστημα (10) χρησιμοποιεί ένα πρώτο ρευστό (16) και ένα δεύτερο ρευστό (18). Το πρώτο ρευστό (16) διανέμεται μέσω της διατρητικής στήλης (14) για να κινεί ή διαφορετικά να παρέχει ισχύ στο υδραυλικό σφυρί (12). Το δεύτερο ρευστό (18) επίσης διανέμεται μέσω της διατρητικής στήλης (14), αλλά ξεχωριστά από το πρώτο ρευστό (16), έτσι ώστε να μην αναμιγνύονται εντός της διατρητικής στήλης (14). Το δεύτερο ρευστό (18) διέρχεται μέσω ενός κοπτικού σφυριού (38) του σφυροτρύπανου (12) και κατευθύνεται ώστε να εκρέει από μία επιφάνεια κοπής (20). Με τον τρόπο αυτό, όταν το σύστημα (10) χρησιμοποιείται, το δεύτερο ρευστό (18) ρέει μέσω της επιφάνειας κοπτικού (20). Το πρώτο ρευστό (16) επίσης εξέρχεται από το σύστημα διάτρησης (10) στο σφυροτρύπανο (12). Πάντως, το πρώτο ρευστό (16) εξέρχεται ανοδικά ή προς το άνω τμήμα του φρεατίου από την επιφάνεια κοπής (20).
