Tóm tắt

The results of 3D numerical simulation of coupled flow and transport processes of light-waste migration in heterogeneous aquifer with brine are described. The study is based on the geological data and monitoring of deep-well injection of liquid waste at Chepetsk Mechanical Plant (ChMZ, Glazov). The buoyancy of light waste is simulated for the post-injection period of 300 years using different conceptual models of heterogeneity. The procedure of 3D geostatistical simulation based on transition probability analysis with TSIM code of the reservoir heterogeneity is presented. The results of the ascending waste migration simulation using SEAWAT2000 code indicate that both the variable fluid density and the hydraulic heterogeneity must be considered in the forecast models for determining the possible waste distribution during the injection and the post injection periods.
