Probably something like this (untested)
(let ((case-fold-search t))
(while (re-search-forward "^[ \t]*#+BEGIN_SRC" nil t)
(let ((element (org-element-at-point)))
(when (eq (org-element-type element) 'src-block)
(if (not (org-element-property :name element))
(let ((i (org-get-indentation)))
(save-excursion (insert "#+NAME: whatever\n"))
(re-search-backward "^[ \t]*#\\+NAME: +\\(.*\\)" nil t)
(replace-match "whatever" ni nil nil 1))))))

Unlike to the previous post, using `org-element' is mandatory in order
to avoid false positive when matching a source block.
