Abstract: Inspired from anomaly low pressure in the middle and deep reservoir of Peleogene in Ji Yang Depression, "water consumption" of main mineral alteration during diagenetic stage is discussed theoretically. Preliminary research result shows that "water consumption" of mineral alteration in diagenetic stage can make formation water greatly decrease. Relevant formation must be in the stage of low pressure without supply of exterior liquid. Pressure differences between relevant formation and wall rock make hydrocarbons emplace easily to form the effective reservoir.
