摘要: 超高压对深层储集层的改善具有多种成因机理,包括降低储集层的有效应力、抑制成岩作用、压力泄漏促进次生孔隙形成、超高压缝的发育、超高压控制下的热循环对流对储集层的改善等,不同机理对储集层的影响程度不同,阐明不同机理对储集层的影响程度可以更精确有效地预测深层储集层的分布。

Abstract: The improvement of overpressure on deep reservoirs includes multiple mechanisms of origin such as the effective stress for bringing down the burial depth of reservoirs, inhibition of diagenesis, secondary porosity associated with overpressure leak-off, development of natural hydraulic fractures, and fluid-flowing convection controlled by overpressure, etc. Each mechanism has its special effect on reservoir quality, by which the distribution of such deep reservoirs can be predicted precisely and effectively.

Key words: overpressure, reservoir, deep zone
