Abstract:
    The invention specially relates to a method that lifting, imaging and calculating the seismic reflection data with an easy, fast algorism, and then embed into seismic data processing software platform to form the final result of seismic data processing and displayed as profile chart of underground medium structure, so it is provides a reliable method for array of exploration and development plan, determination of oil-gas well site or other mineral resource survey. The invention adopts the break-in polynomials of partial differential operator matrix power series to approximate the inverse operator directly. The approximate solution in second order or forth order can be obtained at same time with coming at the equation coefficient matrix. The direction distortion can not be generated, because splitting calculation is not adopted in direction. The aim of the invention is resolving the problems of current big amount of calculation, low accuracy, inescapable chaotic phenomenon, out of overcoming of direction distortion, model experiment and large amount of actual data treatment achievement represents that the invention has resolved the problems very well.
