储层次生石英形成机理研究

The Formation Mechanism of Secondary Quartz of the Reservoir

从石英次生的机理、物质来源、影响因素三方面总结了石英生长的最新研究成果。储层中石英生长受到众多因素的制约,非硅质矿物浓度、石油充注、深大断裂活动、pH值等都会对石英的加大或沉淀产生重要影响。提出了从放射性、矿物转化伴生石英的专属特征等方向切入突破当前的石英次生理论,准确诠释储层石英发育规律。

From three aspects of mechanism,material sources and affecting factors of the secondary quartz,the writer has summarized the latest research results of quartz growth.quartz growth in the reservoir affected by many factors,such as Concentration of non-siliceous minerals,oil injection,deep fault activity,ph value,and so on,all have significant affection on quatrz growth and precipitation.The article suggests that cutting in from radioactivity and characteristic feature of quartz that transformed from minerals,then some breakthrough could be made,and make accurate interpretation about the growth law of quzrtz in reservoir.
