This presentation describes the development of modifications of the drilling tool for getting the holes with a square cross-section.

1. Development of
modifications of the
drilling tool for boreholes
with a square cross-
section
«Drilling tool Bogomolov»

2. Performance requirements of
drilling tools
 Providing the possibility of forming wells with a
square cross-section.
 Unitized body construction, allowing operation
on production drilling machines.
 The possibility of applying on the rocks of the
fortress from 6 to 14 on the Protodyakonov
scale.
 Tool life should not be lower than 50% of the
existing drilling tool to obtain wells of circular
cross-section.

3. Developed a design of cutting-cone
drilling tool

4. 3D model non-separable roller
expander

5. 3D model of a collapsible expander
roller

6. Developed design documentation for the
manufacture of collapsible expander roller

7. Performed power calculations bearing unit in the
new drilling tool

8. Advanced development serial Tricone
"Drilling tool Bogomolov"

9. Results
 Performed technical justification for the
design of drilling tool for drilling holes with a
square cross-section.
 Developed design documentation for the
manufacture of industrial options
dvuhgolosnogo collapsible drilling tool.
 Developed design solutions for different
versions of production "Drilling tool
Bogomolov".
 Registered 8 intellectual property.

10. Thank you for your
cooperation and
