You're including the text "arg1" in the command, not the value of the 
arg1 variable.  (Likewise for arg2 and arg3).  There are some 
unnecessary extra strings in there too.  Your os.system() call, slightly 
simplified, is:

os.system('"C:/Archivos de programa/FWTools2.4.7/bin/ogr2ogr.exe 
"+"arg1" +" -where "+"arg2" +" " +"arg3")

but what I think you meant was

os.system('"C:/Archivos de programa/FWTools2.4.7/bin/ogr2ogr.exe "+arg1 
+" -where "+arg2 +" " +arg3)

There are even better ways to accomplish this task too, but I'm focusing 
on what looks like you ran into with this first.
