Because the main advantage of PetroChina lies in the upstream link of exploration and drilling production; Sinopec's main advantages are in the middle and lower reaches of petroleum refining and terminal product sales. When the price of crude oil rises, the profit of PetroChina will be higher. Sinopec has low profits. Of course, under the current formation mechanism of refined oil prices, the impact is very small. It all depends on consumers. 93# gasoline will reach 15 yuan/liter sooner or later. The goal of international oil speculators is clear-the common people of China.
