苏北盆地古近系泥页岩有机质孔发育特征及影响因素
Characteristics and influencing factors of organic-matter pores in paleogene shale, Subei Basin
摘要
Abstract
Based on the study of Paleogene shale in Subei Basin,and combining results of the Marcellus shale,this paper defined the concept of organic-matter pore,summarized its types and characteristics,discussed its influencing factors and finally concluded evolution rule of organic-matter pore.The results show that organic-matter pores generally refer to pores which are within or at the boundary of organic matter and are genetically associated with it,and they include primary and secondary organic-matter pores.Organic-matter pores display various shapes and are distributed heterogeneously.Especially when they are well developed,the internal structure is a honeycomb connecting component in the layered framework.Temperature,overburden pressure,inorganic mineral and fluid are the external conditions influencing the development of organicmatter pores and organic matter type,while maturity and content are the internal factors controlling the development of organic-matter pores.Organic-matter pores of both Paleogene shale samples in Subei Basin and the thermal simulations have the characteristics of episodic evolution,which is closely related to the fabric evolution and hydrocarbon-generating mechanism during the process of hydrocarbon generation from Kerogen.关键词
