Yes.
Since you've stated a period of time that the subject has been doing it continuously, you should use the had been form.

lucas21cThen, is "I studied English for two years" also wrong?
No. Consider these sentences:
I studied English for two years. This is about the past and you are no longer studying English now.
I've studied English for two years. This may or may not state that you are still studying English now.
I have been studying English for two
