Based on the pennyshaped crack model and the hydraulic fracturing principle,the sand lens reservoir of horizontal occurrence is simplified as a type-I pennyshaped crack of the cap rock. It is due to the fact that the thickness and horizontal distribution length of the reservoir are much smaller than the global cap rock scale. The cap rock fracture resistance of the storage box is analyzed from the view of rock fracture mechanics.
