Example Embodiment
[0054]The present invention will be described in connection with the preferred embodiments in connection with the preferred embodiments. Those skilled in the art will appreciate that the described in the following description is illustrative and not limiting, and the scope of the invention should not be limited.
[0055]The embodiment of the present invention provides an optimization scheme, and is used in a certain target region to break the segmentation and evaluation of the segmentation and evaluation of the opening property in a certain target area, and provides a basis for the next oil and gas enrichment target area. It mainly includes the following steps:
[0056]S100, obtain three-dimensional seismic amplitude data body and drilling production materials for the target area.
[0057]S200, the three-dimensional seismic amplitude data body is used to guide filtering processing, including:
[0058]S201, determine the orientation of the inverted axis by seismic inclination and azimuth;
[0059]S...
