We studied the problem of filtration resistance spatial distribution monitoring which characterizes the capacity of productive layer when extracting hydrocarbons. To solve the problem it is offered to use the tomographic principles based on transformation of the removed integrated equation for the fields of transmission times of hydrodynamic signal. The use to solve the methods of integrated geometry allows us to study internal local heterogeneity of piezoconductivity coefficient of coherent part of deposit. Basic data on interval times of hydrodynamic signal distributions to implement the tomographic scheme can be received on the basis of direct experiment and can be calculated on the basis of the offered model of deposit work as well which coefficients are selected on the basis of deposit development history.
