The paper concerns the problem of two-dimensional pressure stationary filtration in a seam that has filtration coefficient as a contiguous function, and homogeneous zones are square inclusions (blocks) and matrix (fractures). Distributions of velocities, flow lines, movement isochrones of labelled particles, movement time through an elementary cell are found for this double-periodic structure at continuous pressure and normally flow compound at phase interface were found. Based on these substantially two-dimensional hydrodynamic characteristics conclusions are made upon ″convective compound″ of lateral and longitudinal dispersion. The exact solutions obtained are compared with the numerical calculations data obtained by the method of finite differences.
