Porosity and Permeability of the Volcanic Reservoir and Its Influencing Factors: Taking Well Longshen 1 Field of Yingtai fault as an example

摘要: 利用大量储层实验资料，分析英台断陷龙深1井区的火成岩储层物性参数及非均质性的定量评价参数，研究结果表明：火成岩储层物性在空间上变化大，非均质性强。这使得对火成岩有效储层的预测变得困难，本次研究通过成像测井、室内岩石薄片鉴定及铸体薄片分析，探讨各种因素对火成岩储集空间的形成和改造的作用机理和过程，指出岩性是其它因素对火成岩储集物性产生影响的基础，火成岩亚相是物性的主要控制因素，成岩作用及构造作用是影响物性的重要因素，从而使得对火成岩有效储层的预测有章可循。Abstract: Based on substantial experimental material of reservoir, porosity and permeability parameters of the volcanic reservoir and the quantitative evaluation parameters of heterogeneity of Well Longshen 1 field of Yingtai fault is analyzed. The results show that volcanic reservoir physical properties change a lot in space. It has a strong nonhomogeneous. This makes an effective reservoir prediction of volcanic difficulty. Using the imaging logging, indoor rock identification and casting thin section analysis, this study explores the mechanism and process that the various factors on the formation and transformation of the volcanic reservoir space, points out that lithology of the volcanic rocks is the base of other parameters having an impact on the reservoir properties. Volcanic subfacies are the main control factors of physical, diagenetic and tectonic aspects are an important factor on the physical properties, this makes an effective volcanic reservoir prediction have regulations to abide by.
