So, the calcite filling in surface and near-surface is "retention diagenesis" of carbonate cavern reservoir.
因而认为地表、近地表方解石充填过程是碳酸盐岩洞穴型储层的“保持性成岩作用”。
Proper layout of water extracting and filling method of solution mining in tunnel cavern can improve and guarantee the brine production capacity and security production in the middle level.
在硐室水溶中，抽灌水方式的合理布置，可以提高和保障中段产卤能力和安全生产。
