uiuc sororities

in my opinion, the ones that are more academic but still social include
alpha delta pi, phi mu, alpha xi delta, alpha omicron pi, alpha gamma delta & chi omega

Having friends and being social are definitely two huge components of being in a sorority. In my house, studying is also emphasized. We have proctored study hours at our house and are encouraged to monitor all of our studying; I would imagine that most houses have a similar system. Supporting each other's accomplishments (academic/professional and otherwise) is part of sisterhood. However, there is also a visible amount of drinking and some drama, although both can be avoided. In my sorority we never force our members to drink, but it is often part of socializing (as it is in a lot of social circles, not just sororities or Greek life).

once you see all of the house through rush, you will be able to tell which houses do spend their time studying. There are many houses which will have TONS of different personalities in those houses, so you can always find people who fit your lifestyle the best! partying is never a requirement, just an added bonus if you wish to participate!

I would go ahead and rush anyway. Pay careful attention to how the girls talk about one another, the house, and even look at one another. The houses that often aren't ranked on here have very solid sisterhood. You can also look at past grades from the last 4 years to get an idea of where studying is emphasized.
