Embodiment Construction
[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0033] combine Figure 1-10 As shown, the seismic section iterative layer leveling method for deep-water basins according to an embodiment of the present invention may include the following steps:
[0034] S1. Seismic sections are selected according to the geological model.
[0035] Seismic profiles are pre-intercepted along the provenance direction, and faults are avoided during interception to ensure that the seismic profiles have typical and reliable sedimentary information in the area where they are located, laying a data foundation for subsequent iterative restoration of the original shape of the flattened paleogeomorphology.
[0036] S2. Segment the selected seismic section.
[0037] In order to facilitate subse...

The invention discloses a seismic section iterative layer leveling method for a deep water basin. The seismic section iterative layer leveling method for the deep water basin comprises the following steps: S1, selecting a seismic section according to a geological mode; S2, dividing the selected seismic section into a plurality of segments that are sequentially connected; S3, interpreting an auxiliary reference layer in a first segment, and leveling the auxiliary reference layer; S4, creating a new leveling layer in the first segment, and interpreting the leveling layer in parallel with the auxiliary reference layer; S5, sequentially interpreting an auxiliary layer in the adjacent other segments and leveling, and updating the leveling layer in parallel with the auxiliary layer, so as to extend the leveling layer to the segment where the auxiliary layer is located; so that the leveling layer is extended from the first segment to the last segment after the leveling of all segments is completed; and S6, leveling the leveling layer, so that a restored ancient landform sedimentation prototype is obtained. According to the seismic section iterative layer leveling method for the deep waterbasin, the segmented leveling is performed according to the geological features, and the multiple times of leveling iteration effects are superimposed, so that the final prototype sedimentation section is obtained.
Description
technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a seismic section iteration layer leveling method for deep water basins. Background technique [0002] At present, the method of restoring the sedimentary prototype is mainly the leveling method, which uses the sedimentary base level or the maximum flooding surface as a reference, selects the top and bottom of the research sequence, and flattens the top. The flattened top is the original sediment. The shape of the sea (lake) plane and bottom surface at that time is the relative paleogeomorphology of the sequence stratigraphy deposition. The above-mentioned current methods have the following disadvantages: layer leveling method can only restore relatively ancient landforms, and is suitable for shallow water areas, but not for undercompensated environments in deep water areas. Contents of the invention [0003] The technical problem to be solved by the present invent...
