中文摘要：

应用流体包裹体均一温度、镜质组反射率、孢粉颜色指数、色谱-质谱、热解分析、有机酸测定、X射线衍射、镜下鉴定、扫描电镜、电子探针、铸体薄片鉴定等资料,研究了松辽盆地北部中浅层的成岩作用和孔隙演化。结果表明,该盆地中浅层碎屑岩成岩作用可划分为早成岩A期、早成岩B期、中成岩A1亚期、中成岩A2亚期和中成岩B期两个阶段五个（亚）期;只有泉三、四段底部地层进入中成岩B期,整个中浅层的成岩作用并不太强;成岩作用具有从西到东逐渐增强的趋势。中浅层的储层以原生孔隙为主,随埋深增大和成岩作用增强,次生孔隙所占的比例增加,中成岩阶段A期可占总孔隙的24.8%。

英文摘要：

The diagenesis and pore evolution of middle-shallow reservoirs in the northern Songliao Basin were studied by using the data of homogenization temperatures of fluid inclusions,Ro,TAI,GC-MS,Rock-Eval,organic acids,XRD,thin section,SEM,EPMA,blue epoxy resin-impregnated thin sections.The results showed that the diagenesis of clastic rocks in the middle-shallow reservoirs of the northern Songliao Basin are divided into period A of early diagenetic stage,period B of early diagenetic stage,sub-period A1 of middle diagenetic stage,sub-period A2 of middle diagenetic stage,and period B of middle diagenetic stage.Their bottom depths are 500 m,1000 m,1400 m,2350 m and 3000 m respectively;only the reservoirs in the bottom of Member 3 and Member 4 of Quantou Formation in the northern Songliao Basin are located in the stage of middle diagenesis B,so the diagenesis of the whole middle-shallow reservoirs are not very strong.The primary porosity is predominant in the middle-shallow horizons,but the secondary porosities increase with the increase of buried depth and diageneses,and account for 24.8% of the total porosity in the period A of middle diagenetic stage.
