Recently, many scholars have conducted experimental mechanical compaction studies on sandstones, carbonates, and mudstones to visually study the mechanical compaction process and reservoir evolution of sedimentary rocks. However, experimental mechanical compaction studies on the evolution of the compaction process of volcaniclastic rocks have been ignored. Volcaniclastic rock reservoirs are widely distributed across the world. In this study, we analyzed the characteristics and controlling factors of the crushing of volcaniclastic particles during compaction diagenesis from a microscopic perspective through experimental mechanical compaction. These results and datas can provide quantitative compaction background parameters for the quantitative study of volcaniclastic rock reservoir evolution. We took volcaniclastic samples from the Hongtu Hill in the Changbai Mountain area as an example, and experimental mechanical compaction experiments were conducted. Furthermore, image surface porosity and particle analysis statistical methods were used, and the variations in the porosity and image surface porosity under different axial stresses were studied.
