Multi-parameter Calibration Algorithm Based on 4D Seismic Inversion

In order to obtain more reliable gas reservoir information and implement monitoring gas reservoir dynamically, a correction algorithm based on 4D seismic inversion is put forward in this paper. The algorithm uses visualization technology to observe difference between base horizon data and monitor horizon seismic data while using a normalized technology to calculate the correctors and analyze the seismic data. Through an experiment of the seismic data in a work area, the results show that our algorithm is an efficient way to eliminate volume changes made by the exploiting of oil and gas reservoir, and can clearly show the changes in oil reservoir area.
