| 摘 要： | 为了探讨延长气田姚家坡地区上古生界山2段砂岩储层成岩作用特征与物性的关系,在岩心观测、X-射线衍射、铸体薄片及压汞分析的基础上,对储层的孔隙类型、孔隙结构等微观特征进行了深入分析.研究表明,储层属低孔低渗类型,以杂基溶孔、岩屑溶孔为主,主要岩石类型为石英砂岩.研究区砂岩储层所经历的成岩阶段处于晚成岩作用B期,主要的成岩作用包括机械压实和压溶作用、胶结作用和溶蚀溶解作用. |

| Abstract: | In order to study on the relationship between diageneeis and physical property of 2th member of Shanxi Formation in the studied area,the microscope properties of the reservoir such as pore types,pore structure,etc.are discussed based on core observation,X-ray diffraction,casting thin sections and mercury intrusion data.It is shown that,the reservoir is low-porosity low-permeability reservoir,its main pore types are dissolved matrix pore and dissolved cuttings pore,and its main rock type is quartz sandstone.The diagenesis of the reservoir was the B stage of late diagenesis,and main diageneses include mechanical compaction,cementation and dissolution. |
| Keywords: | Yanchang gas-field Yaojiapo area upper Paleozoic Shan-2 member reservoir characteristic diagenesis |
