| 摘 要： | 柴达木盆地南翼山地区新近系储层类型主要为湖相碳酸盐岩.用碳、氧同位素和流体包裹体方法研究湖相碳酸盐岩的形成环境结果表明,碳酸盐岩总体形成于高盐度环境,局部地区浅层样品在成岩过程中遭受过大气淡水的改造.根据孔隙充填胶结物中流体包裹体的均一温度,推断胶结物形成于储层深埋阶段,随后地层发生抬升,导致现今较低深度的包裹体样品具有较高的均一温度.

| Abstract: | The Neogene reservoir rocks in Nanyishan area of Qaidam basin are mainly lacustrine carbonates.Carbon-oxygen isotope compositions and fluid inclusion analyses were conducted in order to trace back the formation environment of the carbonates.Results indicated that the carbonates were precipitated in a high-salinity condition,and parts of the shallow carbonates were modified by meteoric water during diagenesis.Pore-filling cements were formed during the deep burial stage,and thereafter were uplifted as the st... |
