松辽盆地南部青山口组页岩储层特征及孔隙演化
Characteristics and Pore Evolution of Shale Reservoirs in the Qingshankou Formation,Southern Songliao Basin
摘要
Abstract
Organic-rich lake-phase shale serves as the major reservoir for shale oil,and the pore characteristics and pore evolution of shale are very critical to shale oil enrichment,which is of great significance for shale oil exploration and development.Songliao Basin is one of China's most promising basins for continental shale oil resources.The study took the shallow lake-phase Qingshankou Formation shale in the southern part of Songliao Basin as the research object,using cores samples from the X wells,the C wells and the Q wells,respectively.Through field-emission scanning electron microscope,nano-CT scanning,nitrogen adsorption experiments,and high-pressure mercury compression experiments,the pore characteristics and pore evolution patterns of the Qingshankou Formation shale in southern Songliao Basin were explored.The results show that the Qingshankou Formation shale reservoir in the southern Songliao Basin is primarily made of mesopores within organic matter.The degree of pore evolution can be divided into three processes by the maturity of organic matter.关键词
