Automatic velocity picking strategy and method with model constrained
摘要
Abstract
Conventional manual velocity picking in semblance is time consuming and requires a great deal of manual work.A strategy and method of automatic pick velocity from velocity semblance is proposed.Given a single velocity semblance,the RMS velocity was computed as the global best fit to the velocity semblance using monte carlo random fitting method.A initial RMS velocity model can be built with all the RMS velocity function at each CMP calculated.Next,some CMP points can be selected as seeds from the initial RMS velocity model to perform deliberate velocity picking manually.Then an automatic velocity picking can be done constrained by the velocity function that picked at seeds.This method makes velocity picking timesaving and labor-saving.关键词
