There is something wrong with your time. The last bus to PetroChina Training Center is 6: 30, so you can't catch it.

If you take a taxi, the whole journey is more than 60 kilometers, about 200 yuan, which is far away! Why don't you stay in the city first, and the cost of taking a taxi is almost the same, and then leave the next day.

Or take bus No.83 from Beijing West Railway Station to Madianqiao South Station and transfer to bus No.872 to Changling Station. The distance behind is 5km. Take a taxi to 20 yuan. But according to your time, regardless of traffic jams and other factors, you can't get to Changling Station until 9: 30. It's too late for the taxi driver to go.
