| 基金项目： | These research results are key part of a main project carried out in eleventh Five-Year Plan and financially supported by SINOPEC, a academic question that water consumed by minerals during diagenesis and hydrocarbon accumulation is devoted self to study |

| 摘 要： | Inspired from the anomaly of low pressure in the middle and deep reservoir of the Paleogene in the Jiyang depression, this paper theoritically discusses＂waterconsumption＂of the principal mineral alteration during the diagenetic stage. The preliminary research result shows that ＂water consumption＂ of mineral alteration in the diagenetic stage can make formation water greatly decrease. Relevant formations will be in the stage of low pressure without supply of exterior liquid. Pressure differences between the relevant formations and wall rocks make hydrocarbons enter easily to form the effective reservoir.
