Hello, everyone.
This is Enta.
The second one of those φ65-diameter casing rods I introduced last time is finally done lol
Well, the reason it's the second one is that it's still in the prototype stage, lol.
Since each piece has an effective length of 200 mm, five pieces total 1 meter.
Once this is fully completed, I guess this casing will effectively become a double-pipe system, won't it?
However, since we haven't drilled any holes using this casing yet, we don't even know what the results will be at this point.
The loss factor and other factors are likely to be higher than with standard casing. (Quite weak)
I bet a regular drill would break easily, lol.
And I think it won't come off anymore.
So we have to use equipment that's suitable for the job.
There are also issues such as slime discharge, so it seems there are various challenges to be addressed.
Considering all that, it looks like there might be a site where we can conduct experiments around June of this year, so I'm really looking forward to it.
Stay tuned for future experiment results lol
See you later.
