摘要(Abstract):
本文分析了乌尔逊凹陷大磨拐河组的岩石矿物、泥岩演化,孔隙演化等特征,得出压实作用导致了早期孔隙度的降低,自生胶结物充填了粒间孔隙,溶解作用产生了次生孔隙,温度是埋藏成岩过程中的主要因素,成岩阶段分成早期、中期和晚期3个阶段。
This paper analyzes the characteristics such as rock minerals and mudstone evolution etc.of Damoguaihe formation of Wuerxun depression and nakes the following conclucsions:Compaction results in early stage porosity decrease;inte-granular pores are filled by authigenic cement;diasslution leads to secondary pores;tempernture is the major factor during the process of diagenesis and diagenesis stage is divided into early, medium and late periods.
