马朗凹陷条湖组凝灰岩脱玻化孔影响因素与油气关系
Influencing Factor Analysis of Devitrification Pore and Its Relationship with Hydrocarbon in Tiaohu Formation of Malang Depression
摘要
Abstract
The Tiaohu tuff reservoirs in the Malang Depression of Santanghu Basin are characterized by high-porosi-ty and ultra-low permeability. The polarizing microscope,electronic probe,X-ray diffraction,CT scan,SEM,la-ser scanning confocal microscope and other test data are used to research reservoir lithology,physical properties, reservoir space and emphases on the development and influencing factors of devitrification pore in the tuff reservoir. Research indicates that 70%of the reservoir porosity is contributed by the devitrification pore and its development is commonly dependent on tuff properties,vitric ash content and organic acid content. According to the devitrification analysis,the devitrification pore is closely relevant to reservoir and hydrocarbon-bearing properties. This research could provide certain guidance for the further exploration of Tiaohu tuff reservoirs in Malang Depression.关键词
