Abstract：Based on the modified stereo-analytical method of block theory，a new software is developed，updated from Block V1.0 to Block V2.0. The new version added some strong functions，such as the choosing of discontinuity property and available excavation shape. An application to the stability analysis of the surrounding rock mass of the water-tight oil storage in Jinzhou is presented，considering the action of gravity，water and oil pressures comprehensively. The block identification results show：(1) the roof of the cavern is the most dangerous zone，and joint J1 and J2 are the dominant joints，which should be paid close attention during construction and running periods；(2) underground water greatly increased the sliding probability to a certain extent，however，the oil has a favourable effect on the cavern stability.
