Iraq, which depends on oil sales for 95 percent of its public spending, lowered this year its crude price assumption to about $32 a barrel from an initial forecast of $45 a barrel.
The price assumption for 2017 could still change by parliament which has to approve it, a spokesman of Abadi said separately after the press conference.
Iraq is OPEC's second-largest producer after Saudi Arabia with an output of 4.6 million barrels per day.
Iraq sells its crude at a discount to international oil prices that are hovering now at about $50 a barrel.
