Abstract:

At present, the seismic inversion technology becomes most popular. Since the complex of the subsurface formation and the resolution of the data, it is very difficult to get a good result, especially for the well-log-constrained inversion, if the AC curve can not show the real situation of the formation, the inversion
result will be very difference from the true formation. So we can solve this problem by using the simulated AC curve. This article introduces the method and principle of the technology of well-log-constrained inversion and simulated AC curve. This method is based on the preliminary model, using simulated AC
curve instead of AC curve to do the inversion, and it can get very high resolution of inversion result. and this method has got very good result in application.
