Depending on the location of the opening and the rock that will undergo destruction, the nature of the rock breaking drilling rig tools is selected: with diamond spraying, from carbide tools, bits and calibrators (for coreless drilling), blade bits (abrasive, cutting abrasive type), bits (cutting, bicentric, small caliber, for drilling vertical wells), blade reamers of cutting abrasive type, drill bits (K-110, KNSH- 110A), CDD drill heads, diamond bits for CMO.
In order to implement well drilling, it is advisable to understand how the drilling process takes place and what tool is needed for this. Drilling rig tools are categorized by function:
- rock breaking;
- technological;
- optional;
- emergency.
The technological tool used directly during drilling includes: pipes (drill, core, casing), exploration adapters, core breakers.
When drilling, an additional tool is required that serves the technological one. This can be pointed bits, calibrators, centralizers, reamers, tools for sidetracking and sidetracking, cutters for wells.
During the work, it is necessary to construct a running-and-run type (elevators, crown blocks and traveling blocks, pipe holders, swivels, clamps for drill and casing pipes).
In the event of a failure, an emergency drilling tool should be available. To eliminate the accident, you need a fishing and cutting tool, a tool for removing small objects from the bottom, means for stopping the sticking of a drilling tool. A spare kit from leading importers is often used.
