Abstract—

An approach and an algorithm to find the orientation of the pore space of oil and gas reservoir rocks are proposed based on contrast cathodoluminescence images of the surface of polished sections of the rocks obtained using a scanning electron microscope. The microstructural orientation of the pores is found from electron microscopic images of various rocks with a complex pore-space structure and anisotropy of the filtration properties for rocks of various lithological types. This algorithm makes it possible to solve problems related to the anisotropy of filtration properties in petrophysical studies of rocks. The proposed method of finding the orientation is of great practical importance, because the oriented pore space affects the ways of developing hydrocarbon deposits. Determination of the direction of orientation of the pore space allows one to take into account the deviation of fluid flow during its injection into the well and to improve the coverage of oil-saturated reservoirs.

关于岩石孔隙空间的显微结构取向：扫描电镜数据

摘要-

基于使用扫描电子显微镜获得的岩石抛光截面表面的对比阴极发光图像，提出了一种寻找油气储层岩石孔隙空间方向的方法和算法。孔隙的微观结构取向是从具有复杂孔隙空间结构和各种岩性类型岩石过滤性能各向异性的各种岩石的电子显微图像中发现的。该算法可以解决岩石岩石物理研究中与过滤特性各向异性相关的问题。所提出的寻找方向的方法具有重要的实际意义，因为定向的孔隙空间影响着油气藏的开发方式。
