Is it possible to get a PhD by writing only review and survey papers?
It is possible to get a PhD without writing any papers; the formal requirement is of writing a thesis, and many people do just that. So I think the formulation of your question is a bit misleading.
But cutting to what I think is the actual intent behind your question rather than the specific choice of words, the answer is almost certainly that you cannot get a PhD without doing original research. Just making expositions of research already done by others, no matter how detailed or how many citations you get for them, is not what a PhD is about and wouldn’t satisfy the requirements.
