Well-drilling Rig Intro

Well Drilling Rig - water is crucial. This is a great flex fab enterprise opportunity - based primarily on integration of off-shelf materials.

Well - Current Work

idea for a lifetrac enabled pulling apparatus google doc

square tubing could be reused on other projects after well is complete

could wooden 4x4s work? need extra support beams?

A preliminary design

Here is a first rendering of the well drilling rig as rendered in BRL-CAD. The hydraulic pump (green) from the mini tractor is shown mounted with the shaft downwards on the blue sliding frame which moves up and down the side tracks. The hydraulic pump is connected to the purple section of drill string piping which stays centered in the swivel tee allowing drilling mud to flow into it and down the drill string (shown in light green). This purple section of piping is supported vertically by the rotating bearing assembly which rides on the top of the sliding frame. The drill string passes through the red drill collar which bolts down to the gray floor allowing it to be easily removed or swapped for a smaller diameter collar (the square collar flange plate will be the same for all collars allowing for interchangeability). At the bottom of the drill string a simple gray bit is shown which is just a section of 6" pipe with partially covered end caps connected to the bottom of the lowest section of drill string piping.

Please let me know what you think about the pictured design, once I have added the rest of the drilling equipment and after making any changes suggested here, I will post the .g file so other people can play around with it.

open source tricone bit

i think we should start thinking about ways to make tricone bits

Recommend you build "drag" bit, tricone or roller cone bit rely on weight of drill string to break up rock. Most of the designs shown will not have sufficient weight on bit for tricone bit to drill rock.

stack plate steel?

rivet to housing?

welded pipe

want to look into rolling flat plate into tubes and welding seems?

casing

could poly pipe work for well casing?

Yes, PVC pipe is often used to case small water wells, under 8"/200mm diameter borehole.

Polyethylene_from_Ethanol

what size casing is typically used in water well?

You need a minimum of 4"/100mm to allow for installation of cast iron cylinder for India MKII or MKIII by AOV. This will also allow installation of the Afri-Dev type pump.

mud pump

google doc

pump types

what kind of simple designs could be utilized for pumping mud down the drill pipe?

possible plans for reuse of mud pump materials after well is drilled?

does factory farm need this type of pump for other things?

what were some of the pros and cons of the hydraulic pump used on the first drill attempt.

well pump

was the design used on first factory farm well successful? does the design need improvement?

Well - Developments Needed

Well - General

The ability to dig wells allows communities to access underground resources:

-water

-geothermal

Not to mention the power of being able to dig deep holes for support posts or pilings.
