Software Development Based on Stereo-Analytical Method for Block Theory and Its Application in Water-tight Oil Storage

Abstract:

This paper presents the theory basis and programming outline of software Block1.0 employed to determine removable blocks based on the stereo-analytical method for block theory, and the result of the software has proved reliable and efficient by comparing with that of stereo-analytical method . In addition, after detailed investigation and study on geologic conditions of JinZhou water-tight oil storage cavern, by using Block1.0 and Unwedge software, respectively, we find all removable blocks relating to each excavation plane of JinZhou water-tight oil storage cavern and systematically calculate the magnitude of removeable blocks with respect to the distribution of discontinuities and the position of excavation planes. The results show that Block1.0 can provide a more reliable basis for the smart reinforcement design of the cavern and be more adaptive to practicality.
