Abstract: The effects of the deep fractures of crust and block tectonic movements on the fluid migration in sedimentary cap rocks are elaborated. A lot of real data from the large-scale petroliferous provinces in Russia such as Caucasia, West Siberia and Tartar are analyzed. It is indicated that ascending reserves and production rates are universally found in old blocks and abandoned wells in old oilgas fields that have been developed for many years. It is concluded that the emergences of such phenomena are closely related with the periodical changes of the deep crust dynamic environment.

Key words: modern crust movement, reserve ascending, deep fracture, sedimentary cap rock, fluid activity, earthquake activity, in-situstress
