激光扫描共聚焦显微镜( laser scanning confocal microscope,LSCM)具有分辨率高、制样简单、具有一定穿透能力、集激光扫描和数字图像处理为一体等优点。用于研究储层中的微孔隙,其能够快速、准确、直观地提供微孔隙的孔隙结构与面孔率等信息,本文通过对致密砂岩粒缘微缝、砂岩长石粒内溶蚀孔、云母内微孔、火山凝灰岩脱玻化气孔和英安岩溶蚀微孔进行激光共聚焦三维扫描,可以检测出孔径在0?1μm以上的微孔隙,有助于分析微孔隙特征与油气集输之间的关系,对天然气储层和致密砂岩储层的勘探和开发具有重要意义。

Laser scanning confocal microscope has the advantages of high resolution, convenient specimen preparation, owning penetrating power, having both laser scanning and digital image processing, and so on. It can quickly, accurately and intuitively provide the pore structure and facial porosity of micropores. Based on the scan by laser scanning confocal microscope on the tight sandstone grain edge slit, the feldspathic sandstone grain dissolution pores and pores within mica, volcanic tuff devitrification porosity and pore dacite karst erosion copolymer, the aperture with more than 0?1 μm can be detected, which is useful for analyzing the relationship between porosity character and oil and gas gathering and transferring. It is important for tight sandstone gas reservoirs and reservoir exploration and development.
