摘要

致密储层孔隙结构评价对致密油勘探开发具有重要意义。利用岩心观察、铸体薄片、扫描电镜(SEM)、氩离子抛光—扫描电镜(Ar-SEM)等多种方法,对比研究了致密砂岩、致密白云岩和泥页岩3类致密储层的孔隙结构特征及差异性。利用ImageJ软件处理和分析SEM图像及Ar-SEM图像。对SEM图像进行伪彩色增强,突出显示其孔隙结构特征,再利用灰度值定量识别了致密储层的孔隙;对Ar-SEM图像进行二值化处理,定量评价了储层中不同孔隙类型的孔隙数目、孔径大小、面孔率、分形维数等参数。

Abstract

Micro-structure evaluation of tight reservoir is the basis of tight oil exploration and development.Taking the tight reservoir of Ek2 in Cangdong Sag as an example,apply the core observation and description,casting thin sections,scanning electron microscopy (SEM),argon ion polishing and scanning electron microscopy (Ar-SEM) analysis,to study the pore structure characteristics of tight sandstone,tight dolomite and shale reservoir.On this basis,using ImageJ software to process and analyze the SEM and Ar-SEM image.The SEM image pseudo color enhancement can highlight the characteristics of pore structure,and a comparative research can be done on these three tight reservoirs such as throat shape,size,distribution and connectivity etc.After two value processing of Ar-SEM images,we can quantitatively evaluate the reservoir pore number,pore size,face rate parameters.
