| 摘 要： | 海拉尔盆地乌尔逊凹陷南部铜钵庙-南屯组砂岩类型主要以岩屑长石砂岩为主,有少量长石砂岩和长石岩屑砂岩.成岩作用包括压实作用、胶结作用、交代作用、溶解作用等.孔隙度和渗透率随埋深的增加而逐渐减小,在1 500 m左右、1 850～2 050 m、2 300 m左右和2 600～2 800 m出现4个相对高孔隙带.造成相对高孔隙带出现的原因是原生孔隙保存和次生孔隙发育,压实作用、胶结作用较弱和自生粘土矿物包壳、自生石英微晶存在,有利于原生孔隙的保存;有机质热演化、粘土矿物转化过程中,次生孔隙形成. |
| 关 键 词： | 海拉尔盆地 砂岩 相对高孔隙带 原生孔隙保存 次生孔隙形成 |

| Abstract: | The types of sandstone from Nantun and Tongbomiao Formation of Wuerxun depression in Hailaer basin are mainly debris-feldspar sandstone,sightly feldspar sandstone and feldspar-debris sandstone.The diageneses include compaction,cementation,metasomatism and dissolution,etc.With depth increasing,the porosity and permeability decrease.There are four relatively high porosity arears in about 1 500 m,1 850-2 050 m,2 300 m and 2 600-2 800 m.The reasons of relatively high porosity areas appearance are the preservati... |
