The conversion of abandoned butted well salt cavities into underground storage facilities holds immense significance for safeguarding energy security and improving the ecological environment. A significant barrier to reconstruction these old is limited comprehension their complete morphology, caused by residue coverage. three-dimensional seismic techniques excel in identifying complex geological structures but have a understanding cavity thus forward simulation method utilized study response patterns. Based on 3D data, logging measured shape parameters from Yexian mine region Henan Province, China, model observation system were established. characteristics cavern model, encompassing five distinct morphological attributes such as spacing, diameter, height, sediment horizontal connection channel thoroughly investigated. findings show that roof exhibits distinctive “two peaks sandwiching strong valley” feature, with positions valley remaining aligned serving reliable indicator cavity’s top surface. width waveform an exponential amplification effect relative width. residue’s surface presents “upward-opening arc” wave peak downward shift diminishes height increases. This forms circular feature reflection waveform, always located upper half this waveform. channel’s bottom surfaces exhibit contrasting patterns, position aligning trough shifting brine cavern, residue, mainly chaotic reflections. There are identification top, connecting simulation. research provide valuable guidance morphology real based data accelerating construction facilities.
