Like, one section would be (for example) 100ft long, then you'd bolt on further sections to gain the depth?
I would imagine that the amount of torque stresses exerted on the joints, would have been phenomenal!

Interesting, Torog.

Howdy Res,

Actually,the drill bit is just that , a component in and of it's self..it's less than two feet long,and usually consists of three rotating cones,that mesh together and are tipped with hardened teeth or diamond-tipped teeth. Drilling mud is pumped down the pipe and comes out in three jets that both cut and clean ,the bit and hole. The bit is attached to the collars,which are in sections around 30 feet or so,they serve as weights that help the drilling string,to drill straighter. We did use heavy-duty drill pipe,each section,about 30 feet long,and pulled em out in 90 foot sections,three drill pipes at a time..that's what we call a triple drilling-rig,there are also doubles and singles. The entire assembly of drill-bit,collars and drill-pipe,is called the drill string. The typical weight of a 2 mile string,is around 682,000 lbs..and up. There are deep-well earth rigs that are rated up to a 1,750,000 lbs..they can drill down to 38,000 feet or more.

Have a good one...Torog
