摘要: 硅质岩在四川盆地中二叠统茅口组广泛发育，研究茅口组硅质岩对指导油气勘探有着重要的理论意义。本文在阅读大量文献的基础上，详细论述了四川盆地中二叠统茅口组硅质岩研究现状，同时对硅质岩进行了产状分类，并且详细介绍了各类硅质岩的形成环境、硅质来源以及成因模式的地球化学判断依据。在前人工作的基础之上探讨层状硅质岩与茅一段非常规油气储层的关系以及非层状硅质岩与茅二段、茅三段白云岩储层的关系。
Abstract: Cherts are widely developed in Maokou Formation of Middle Permian in Sichuan Basin. Researches on cherts in Maokou Formation have a prolonged influence on petroleum exploration theoretically. After long-period investigates, this study summarizes researches about cherts in Maokou Formation, mid Permian, Sichuan Basin, classifies the occurrence of chert, and introduces the formation environment, source of chert and geochemical judgment basis of genetic model of all kinds of chert. On the basis of previous work, this paper discusses the relationship between stratiform chert and unconventional reservoirs in 1st member of Maokou Formation, and the relationship between non stratiform chert and dolomite reservoirs in 2nd member of Maokou Formation and 3rd member of Maokou Formation.
