Study On The Solid And Gas Coupling Model Of Gas Seespage In Layered Salt Rock Storage And The Stability Of Storage

The rock salt deposit is a kind of geological condition and the physical mechanics special deposit, its mechanics performance is good, the extremely low penetration coefficient and the performance of damage self resilience cause the rock salt deposit oil and gas storage to become "highly the strategic security reservoir".Our country's rock salt deposit belongs salt layers with interlayers and the impurities ,they mainly are the gypsum, mudstone and so on . The oil and gas storage constructed in the non- isotropic layered rock salt deposit has more complex mechanicial and the technical question than the one constructed in the thick rock salt deposit has. Not only the permeability of the rock salt body, the convergence of the cavity and the stability of jambs must be considered , but also the heterogeneity of the interlayers must be full considered, like the permeability of interlayers and layers , the difference of interlayers . Salt rock, the oil and gas storage constructed in the layered rock salt deposit s is quite complex depth geotechnical engineering, involving multi- disciplines.The research on gas leakage in the layered rock salt storage and the storage long-term stability may provide the beneficial reference on the construction of the oil and gas storage in the similar salt deposit. So the research has the extremely vital significance and the value.In this dissertation,the study on the solid and gas coupling model of gas seespage in layered salt rock storage and the stability of storage is carried, through the experimental...
