Hello, can I obtain the visa on a Venezuelan passport in Holland?

Due to holidays next week as well as the presidential elections in Venezuela it is impossible to get a visa here. As I have dual nationalities and my other passport was issued in Portugal I wonder if it is feasible to get it in The Hague as the invitation letter was issued on my Venezuelan passport number and I am scheduled to oversee the acceptance of an airplane from Oct, 3rd until Oct 20th in Guangzhou
