The simple answer is that if refineries shut down the strategic petroleum reserves (SPR) would not help. The SPR consists of crude oil - unrefined products. While the US consumes about 21.4 million barrels per day of petroleum products, those barrels are refined products: gasoline, jet fuel, diesel, etc.

US oil consumption in 2006 was 20,588,000 barrels/day (Wikipedia), = 2.0588 x 107. 112 billion = 11.2 x 1010. So this would last 11.2/2.0588 x 103 days = 5.44 x 103 days or 5,440 days = 14.9 years.
