My layman's idea for stopping the leak:

Insert a drill pipe into the well with some sort of expandable yet sturdy bag tucked into the end. Once the pipe is fairly deep inside the well, pump a dense liquid into the pipe expanding the bag similar to an angioplasty procedure. Then cap the well from the top once the flow is stopped or reduced significantly.

Another similar solution would be to attach high explosives to the drill pipe and collapse the well from deep inside.

Have these approaches been considered?

I think that a problem with this idea is that the "expandable yet sturdy bag" would have to be able to withstand great pressure, not just of the oil itself but to survive a mile underneath the ocean.
