They did that indeed, especially in the early days to avoid a complete collapse, but since then it's not the primary mechanism at stake.
This is a great reminder that keeping your money afloat is not that hard as long as you can export. (For the record, what destroyed Venezuela comes from the fact that they needed to import light oil in order to process their heavy one. Once the sanctions cut the input flow, the output flow dried up pretty quickly and it was game over)
I don't think it will matter long, given the catastrophic failure of the Russian military (which is currently demilitarizing Russia pretty quickly, how ironic), but from the economics PoV it's still interesting to witness.
