结果表明,火山岩可划分为火山爆发相、火山喷溢相和次火山相,其储集性能较差,不能形成油层,但火山爆发相和火山喷溢相中的火山碎屑岩和玄武岩的储集性能稍好,对储气可能有效;火山岩周围地层由于受烘烤而出现温度异常,影响了周围泥岩中的有机质成熟度。
The component of pyroclastic rocks are complex.
火山碎屑岩岩性复杂,因此骨架参数难以选择,影响孔隙度的计算效果。
Currently, As the scale and depth continues to increase on oil and gas exploration, in many parts of the world, An increasing number of hydrocarbon reservoirs are found in pyroclastic rocks, for example, there develop a large-scale reservoirs of pyroclastic rocks in Hailar Basin of China, Therefore, people add important attention to research the evaluation about pyroclastic rock reservoir.
由于火山碎屑岩岩性的复杂性,致使其测井响应特征多变,规律性很差,影响了测井解释的符合率。
Rock fragments, including volcanics, are common, and the matrix consists largely of kaolin and illite.
