| 摘 要： | 本文通过对岩芯、岩石薄片的观察,对乌尔逊地区南屯组储层进行了成岩作用研究,结果表明压实作用和胶结作用是深层储层物性变差的主要因素;溶蚀作用形成的次生孔隙成为南屯组储层主要储集空间;有机质热演化、淋滤作用和异常高压所导致的溶蚀作用是研究区次生孔隙形成的主要原因。

| Abstract: | By researching the observation of rock core and thin sections of Nantun reservoir in Wuerxun depression,we study the diagenesis,the results show that compaction and cementation of deep reservoir is a major factor of deterioration of physical properties;secondary porosity of dissolution into the formation is the main reservoir space.Thermal evolution of organic matter,leaching and abnormal pressure caused by the dissolution of the study area is the main reason for formation of secondary porosity. |

| Keywords: | Wuerxun depression secondary porosity dissolution high-quality reservoir |
