I helped a man with his well years ago, like yours it was deep, 100 feet IIRC. We used a rope (bad idea),the rope hit the side of the pipe about 3/4 way down. cut the rope, what a mess, took us hours to get it back up as the rope jammed on top of the pump. He used a plastic pipe that was flexible, we used the pipe to pull it back up.
Your case is ridged pipe, it takes a crane to lift and hold so it can be unscrewed. you do not want 100 feet of pipe sticking up in the air, it will fall. You could build a rig, use a come a long, make a clamp to hold the pipe up so to reset the come a long for the next lift. My guess it would take more than a few hours.
Rig would need to be big think wood or steel, gona cost a good bit, plus the come a long. Spend the money and let someone else take a chance on dropping the mess back down the well, you get to sit back and watch. The price is not that bad.
