PROCESS OF TREATMENT OF DRILLING FLUID Russian patent published in 1994 - IPC

Abstract RU 2007545 C1

FIELD: mining industry. SUBSTANCE: part of flow of treated drilling fluid is transformed into high-speed jet for action on rock which includes active chemical substances in its composition. Circulation of drilling fluid in borehole is organized in compliance with direct flushing circuit. Concentration of active chemical substances in upward current is checked and if it exceeds established values action on rock of high-speed jet is stopped. When this concentration diminishes action of jet is resumed. Use of invention makes it possible to control process of treatment of drilling fluid while stripping rock masses lying below and having different properties or while drilling boreholes. EFFECT: improved drilling efficiency.
