You can patch it with a coupler if you saw a coupler in two lengthwise and glue both halves to the pipe and install a hose clamp to it. Make sure you use plenty of cement on the inside of the coupler AND to the edges where you cut it. Not a major job, just a little messy and takes a little time.
IF, the vent pipe you drilled thru is inside the tank, don't worry about it. In fact, if it is inside the tank, I would try to cut it off and pull the end out of the tank thru the discharge hole, otherwise it will eventually block the discharge. You might be able to cut it loose on the roof and pull it up to cut the end off and then shove it back into the tank and re-anchor it at the roof.
