ABSTRACT
Wan[11] et al. had studied the fluid migration and dissolution mechanisms in the process of constructing the cavity of salt rock gas storage concluded the cavity expansion model in the process of constructing the cavity with pure salt rocks. Wei-guo Liang[12,13] et al. proposed the horizonal projected jet dissolution mining cavity-construction technics with changing the oil underlay to the connected double wells; Wei-guo Liang, Su-guo Xu et al. had obtained the dissolution characteristic curve, dissolution rate and dissolution velocity equation of the glauberite in the water through the its dissolution experiments under the normal temperature conditions; De-yi Jiang, Jie Chen[14,15] et al. had proposed the constructing technics of double shaft horizontally coupling in salt cavern reservoir. Song Ren, Jie Chen[16] et al. had set up a similar model experiment platform to simulate the cavity flow field in cavity-construction phase and studied the cavity flow migration law in cavityconstruction phase by using staining.
