Abstract: The miscible pressure is a important foundation to define miscible flooding using in the reservoir . The best method of miscible pressure determination is capillacy test.The authors forecast the minimum miscible pressure by some experience formula,and the miscible pressure of oil in five sections of Dagang oilfield is determined.Then,the authors analysis gas oil ratio,recovery ratio in different flooding volume.

Key words: miscible flooding, miscible pressure, determination
