After you beat Red, and got your kanto starters, Oak will give you a red orb. Go to the Embedded Tower, which is in a cave at route 47, and Kyogre should be there.
To get Groudon, you need to trade someone that has SS.
To get Rayquaza, you have to show Oak your Kyogre and Groudon and he should give you a Jade Orb. Go back to the Embedded Tower and Rayquaza should be there.
