Abstract:
1. A system for injecting high pressure abrasive fluid into an abrasive jet tool in a wellbore, comprising: an abrasives hopper; a slurry tank connected to the abrasives hopper; a low pressure abrasive pump connected to the slurry tank, wherein the low pressure abrasive pump comprises abrasive-resistant materials; a first high pressure vessel connected to the low pressure pump through a first high pressure valve; a slurry circulation line for circulating slurry from the slurry tank through the low pressure abrasive pump past the abrasive hopper and back to the slurry tank; a high pressure non-abrasive pump connected to the first high pressure vessel through a second high pressure valve, wherein the high pressure non-abrasive pump is configured to pressurize the first high pressure vessel; and an abrasive jet tool connected to the first high pressure vessel through a third high pressure valve.
