The connectivity of water curtain between holes must be known to ensure water seal effect of artificial water curtain system of the underground oil storage caverns. The permeability characteristics of the fractured rock mass is analysed based on packer test and validity test of the water curtain holes of the China's HuangDao’s national petroleum reserve underground water seal oil engineering, puts forward the connectivity judgment criterion of water curtain holes, and evaluate the connectivity of water curtain system of underground oil storage caverns. This criterion has been used in the connectivity evaluation of water curtain system of the HuangDao’s national petroleum reserve underground water seal oil engineering. Research provides a basis for the dynamic design of water curtain system of underground oil storage caverns, reduce project cost.

Element Method

The distribution of hydraulic pressure in fractured rock mass surrounding caverns after excavation and technique of stochastic generation of joint network are investigated based on discrete element method. In order to seal the oil in underground caverns with water in the actual engineering, a water curtain with water pressure is installed, and the changes of hydraulic pressure are simulated with a series of curtain pressures. It is shown that some joints that have been drained out during excavation can not be saturated if the water curtain pressure is less than a certain value. Water curtain pressure with a certain value gives a strong safe guarantee of saving oil in the underground petroleum storage caverns.
