Drilling Rigs Used By Different Industries



drilling courses in Rawalpindi.

Drilling rigs are essential tools of the trade for many industries. They generate powerful forces through mechanical, electric and hydraulic means. Some rigs are also driven by pneumatic and steam power. Technical Data used in the field explained in drilling courses in Rawalpindi.
Rigs are used extensively by the oil and gas industry, mining and construction and to create water wells. They dig thousands of meters with efficiency and some types test rocks and mineral deposits and also aid in setting up tunnels. Depending on requirement, rigs can be small, portable devices or massive set ups to get into the earth. Some more details of drilling courses in Rawalpindi are as under.
Cable tool drills are used to build large, deep water wells through bedrock. They consist of drill strings tipped by drill bits that bore through rockheads, unconsolidated soil and finally, bedrocks. Broken rock and soil are removed using a bailer.
No longer used extensively, cable tool rigs nevertheless serve an important function in rural areas where the cost of drilling with more modern devices is high. And despite being slow, they still remain essential devices for countries that continue to drill with cable tool rigs.
Direct push rigs push rather than rotate a drill bit. They use hydraulic down pressure, rapid hydraulic hammering and the weight of the rig itself to bore into the earth.
This process may seem slower than using rotary drill bits but it has advantages. Unlike rotary rigs, a direct push drill doesn't require oil or foam to enhance drilling, unwanted waste generated from rock fragments is minimized and ease of mobilization and demobilization is offered. The rigs are smaller too which makes them ideal for use in difficult terrain and remote areas.
Sonic rigs are based on relatively new technology and can be very efficient and fast. They use vibrating rotary drills to disturb soil. Drill bits may also use an up and down motion. Soil particles that come into contact with the drill bits are fluidized and this reduces friction. And since fluidization occurs only a few millimeters away from the drill bit, it doesn't affect soil sample quality.
