THE APPLICATION OF MULTIPLE PARAMETERS LITHOLOGICAL INVERSION TO COALFIELD SEISMIC EXPLORATION
摘要
Abstract
The method of model-based seismic inversion makes use of sound velocity logging or density logging constrains to get wave impedance inversion information. However,when the difference between the purpose layer and the surrounding rock is small,it is difficult to solve the problem of layer contrast through the information. In fact, apparent resistivity and artificial gamma logging can provide lithological information of other strata. The inversion constrained by multiple parameters has more acute effect in distinguishing lithologic characters. The method of double logging curve fusion makes use of two different logging curves to fuse and transform into a imitated density curve, which can highlight the density anomaly of coal and magmatic rocks at the same time. Multiple parameters lithological inversion can be realized by the imitated density curve constraint.关键词
