I am unfamiliar with using the plural form of property, as you are trying, at 
buffer-level nor do I see  documented possible here:
https://orgmode.org/manual/Property-Syntax.html#Property-Syntax

try this:

#+property: header-args:sh :var user="loris"
#+begin_src sh
echo user: ${user}
#+end_src

Important: After adding or modifying the #+property line, you will need to 
instruct org to "refresh your local setup" which I typically accomplish by 
positioning the point on that line and typing C-c C-c
