Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0038] An embodiment of the present invention provides a method for optimizing stratum slices, the method comprising:
[0039] Step 1: according to the seismic geological horizon calibration, determine more than one seismic marker layer corresponding to the sequence near the target layer, and determine the seismic reflection time range of the seismic sedimentology stratum slice of the target layer according to the seismic marker layer, Obtaining a plurality of stratum slices according to an equal-scale subdivision method within the seismic reflection time range;
[0040] Step 2: According to the data of all wells within the research area in the target layer, obtain the ratio of the thickness of all wells from the top of the target laye...
