Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
(nearly) of the relief well with chemical explosives.  So I would be creating a line source for the explosion rather than  a point source.  I would be seeking to crush the gusher along most of its length, rather than just at one point.  The impact from the explosion would fall off with distance, rather than distance squared, which should enhance its effect.  

Alternatively, by choosing a sequence of detonation times, the explosion could be focused to highten the effect at one point in the gusher column.  

And following your calculation, the energy would then approach the kiloton range.  

That doesn't mean it would work, though.  

The Fates are kind.

I don't know what the temperatures are at those depths and pressures. The Russians had to cool the bore before they inserted the nuke. Above a certain temperature TNT becomes unstable, I believe. Cooling and then inserting a large quantity of TNT might be problematical. I should stick to qualitative analysis. :-)
