2001 Chevy Silverado Blue smoke from exhaust

At startup the vehicle runs great - very little smoke, a little high fuel smell, but I think thats normal. After warmed up it smokes a lot and when its at an idle then you go to take off it leaves a cloud, then clears up to moderate smoking. The injectors were changed at 117000 miles. And the engine runs great other than the smoke. Im guessing that oil is left on the cylinder walls and then burns off at acceleration, its a pretty distinct blueish white smoke so I dont think it has to do with the fuel mixture. My question is what your best guess is as well as wether it would be worth it to pull the cylinders out and change the rings or if something else would be a good idea? And I donated 20 last time, Im sure Ill be back if you continue to help, thanks.
