摘要：

本文在对储层矿物、岩石在碱性驱替剂中的化学行为系统研究进行概括的基础上提出了碱性成岩环境有助于砂岩储层次生孔隙发育这一全新的观点,并提出了单旋回成岩环境体系中的“酸-碱链式反应”模型。最后通过岩石矿物组成分析和文献调查证实了碱性成岩环境确实存在。显然,这种观点的应用会对油田油气勘探产生积极的影响。

Abstract:

On the basis of systematical research on the chemical behavior of reservoir minerals in alkaline-flooding agents, the authors put forward a mew idea that alkaline diagenetic setting is favorable for the formation of secondary pores in sandstone reservoir. Furthermore, the authors suggest an “acid-alkaline chain reaction” model for a mono-system, and prove the existance of alkaline diagenetic settings through rock mineral composition analysis and the reference of literatures. Obviously, the idea has positive effect on oil /gas exploration.

Key words: Reservoir mineral, Secondary pore, Alkaline flooding agent
