砂岩储层孔隙度和渗透率的影响因素

The influential elements of sandstone porosity and permeability

砂岩储集性的影响因素，研究方法很多，计算方法和先进仪器的发展，对以前不能认识的因素也有了较大突破。但是根本的因素还在于以下三个大方面：一、沉积作用；二、成岩后生作用；三、粘土矿物。本文就这三个方面进行了深入的论述，并归纳总结了它们对砂岩孔隙度、渗透率的影响程度和在研究中应注意的问题。

There are many methods to study the influential elements of sandstone property of storage.With the developnent of calculate methods and advanced instruments, Man get to know the ele-ments which they couldn't know before. But the basic elements of influence are following: Ⅰ de-position. Ⅱ. diagenic epigenesis. Ⅲ. clay mineral. This paper discusses the three elements and sumsup how they influence the sandstone porosity and permeability It also summarizes what we shouldpay attention to in the study.
