摘要：

应用偏光显微镜、环境扫描电镜、恒压压汞以及近年来发展起来的恒速压汞技术对鄂尔多斯盆地神木地区上古生界太原组和下石盒子组天然气储集层进行了研究。研究区该储层岩性以粗粒、巨—粗粒岩屑石英砂岩为主，石英砂岩、岩屑砂岩为次，由于成岩作用强烈，残余原生粒间孔基本全部丧失，而煤系地层提供的大量有机酸以及丰富的可溶性组分，使太原组形成了以溶孔为主的储集层，下石盒子组则主要以高岭石晶间微孔为主。恒速压汞的测试表明，太原组、下石盒子组储集层孔隙结构差别明显，太原组储集层孔径大、孔喉比大，而下石盒子组孔径小，孔喉比接近于1∶1，属于较差的孔喉配置。

Abstract:

By means of microscope,ESEM,constant-pressure mercury penetration and constant-speed mercury penetration，the physical property of Taiyuan and Lower Shihezi Formation reservoirs in the Shenmu area of Ordos basin is studied in this paper.The lithology of reservoirs is mainly composed of coarse and huge-coarse quartz sandstone and debris sandstone,and secondarily of grain quartz sandstone and boulder-coarse debris quartz sandstone.Owing to the intense diagenesis，most residual origin porosity had been lost.The abundant organic acid and resoluble component from coal measure improve the physical property of Taiyuan Formation reservoir.But,the Shihezi Formation reservoir is characterized by kaolinite intercrystalline micropore.The results of constant-speed mercury penetration show that the pore structure of Taiyuan and Shihezi reservoir has great differences.Compared with the Lower Shihezi Formation，Taiyuan Formation reservoir has larger bore diameter and higher ratio of pore throat,building up a favorable pore throat pattern.

Key words: Ordos basin, Upper Paleozoic, Reservoir, Dissolved pore, Constant-speed mercury penetration, Sedimentation, Diagenesis
