Bit Hydraulics

Course Overview

Bit Hydraulics explains the interaction of hydraulics with other drilling and mud parameters, for an understanding of overall drilling efficiency. This course include complete references of graphs, tables, equations, and rules for hydraulic calculations. Example problems walk the student through total hydraulic design, from liner size selection to actual jet sizing. An interactive “what if?” exercise permits the student to observe the effects of individual properties on bit hydraulic horsepower. Although aimed primarily at tri-cone bit hydraulics, a section on PDC and diamond bits is also included.

Course Objectives

• Explain terms and equations used in hydraulics.
• Describe the effect of hydraulics on rate of penetration.
• Explain optimum hydraulic horsepower and impact force.
• Calculate optimum jet sizes (based on both theoretical and actual field data).
