Study on the Forecasting Method of Total Dissolved Solids Based on the Acoustic Logging and Electrical Logging

摘要

Rock porosity and formation resistivity,the two strata factors of total dissolved solids (TDS) of underground water are analyzed in this paper.And a model reflects the relevance of sandstone aquifer apparent resistivity and corresponding formation water total dissolved solids via least square method which is from the derivation of porosity and buried depth.Also,the prediction of total dissolved solids and flat trend distribution of eight wells in Songliao plain and finally fulfilled the regional water quality assessment in there.From the result,we can conclude that our model can be introduced to total dissolved solids forecasting and underground water quality evaluation.
