Abstract

The invention discloses a seismic inversion reservoir stratum forecasting method for an overthrust-containing complex structure, and relates to the technical field of a method for forecasting reservoir strata in oil-gas exploration and development. The method comprises the following steps of: (1) extracting seismic wavelets; (2) demarcating a geologic horizon by well logging data, and corresponding the time-depth relation of the well logging data and seismic data one by one; (3) importing a seismic interpretation horizon and a seismic interpretation fault, and establishing an initial model of seismic inversion by an overthrust-containing modeling method; (4) calculating an inversion result by a model-based inversion algorithm; and (5) performing seismic interpretation on the seismic inversion result. When the method is used, the seismic inversion of the reservoir strata of the overthrust-containing complex structure makes the breaking points distinct and the heading side data of the fault credible and increases the forecastable area, and the problem that the fault area of the seismic inversion reservoir stratum forecasting of the overthrust-containing complex structure in the conventional seismic exploration is difficult to interpret is solved.
