You can't match against the query string in a RewriteRule , you also don't want to blindly rewrite the URI since the rule right before it does that, and you'll just cause a redirect loop. Change your second rule to:

RewriteCond %{THE_REQUEST} ^(GET|POST|HEAD)\ /readmore\.php\?
RewriteCond %{QUERY_STRING} postid=([^&]+)
RewriteRule ^ /blog/%1/ [L,R=301]
