1results about How to "Reduce frequency difference" patented technology

The application discloses a loess plateau transition zone frequency consistency processing method, which comprises the following steps: obtaining a common midpoint / common reflection point gather A of a target area; obtaining a corresponding stack / migration profile according to the common midpoint / common reflection point gather A, and extracting a frequency attribute FA along a target layer on the stack / migration profile; processing the common midpoint / common reflection point gather A to obtain a high-resolution gather B, stacking the high-resolution gather B, and extracting a frequency attribute FB along the target layer on a profile obtained through the stacking; determining an expected main frequency FH conforming to a feature of the target area data; determining weight coefficients x and y of the frequency attribute FA and the frequency attribute FB according to a relationship among the expected main frequency FH, the frequency attribute FA and the frequency attribute FB; applying the weight coefficients x and y to the gather A and the gather B respectively to obtain an expected main frequency gather C; and stacking the expected main frequency gather C to obtain a corresponding result profile.
