Abstract:In this paper, setting rock mass integrity exploration and evaluation project of Jiumushan in Fushan district in Yantai city as an example, which is an alternative base of water sealed underground petroleum storage caverns of national oil strategy, the principle of tomographic static correction technology is introduced, and the application result of tomographic static correction and refraction static correction are compared. It is showed that refraction static correction is not good in complex area due to large variation of lateral velocity and absence of stable refraction layers. However, the timelapse tomographic static correction method can invert the surface velocity model accurately and solve the static correction problem of complex surface. The grading profile of rock mass integrity, which is calculated by using the surface velocity model profile established by tomographic inversion, is combined with tomographic static correction reflection wave profile in integrated interpretation. The geological exploration task has been completed successfully and the geological problems in this exploration project have been solved.
