Abstract
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.
