摘要: 火山岩的矿物组分复杂多变,各类火山岩岩石骨架密度均变化范围较大,很难用常规方法求取其孔隙度。ECS测井可提供地层主要造岩元素和各种氧化物的百分含量两类测量结果,他们与岩石骨架密度紧密相关。据此可建立能表征不同的火山岩骨架密度参数的计算模型,并结合密度测井计算火山岩储集层孔隙度。实践证明,该方法在准噶尔盆地取得了良好的应用效果。

Abstract: The mineral components of volcanics are complicated and variable. The density of matrix of each type volcanic rock varies widely, so it is difficult for using conventional methods to calculate its porosity. Element capture spectrum (ECS) log can present two measurement results including the percentage of primary rock-forming elements and various oxides of formation, which are closely related to density of rock matrix. According to this, the model for calculating density of matrix of volcanic rocks is established. Integrated with density log, it is used to calculate porosity of volcanic reservoir. Practice shows that the method has good geological application effect in Junggar basin.

Key words: Junggar basin, volcanics, reservoir, porosity, ECS log tool
