Abstract: The ability of evaluation of sandstone reservoir has been greatly improved sine the use of electronic computer in processing well log data.But it is still difficult to analyse reservoirs with high water saturation,or reservoirs with high residual oil saturation and aquifers containing oil etc..Based on the studies of the reservoirs and aquifers in respect to their oil saturation,porosity,lithology factor and other independent parameter:relative to water invasion and water distribution etc..an optimun discrimination is proposed for the accurate evaluation of reservoirs and aquifers using discriminant analysis as a tool.The final recognition is achieved on the electronic computer.This new technique and processing program has been widely tested and verified in the Shengli oil field and other fields in east China,with precision up to 90 Percent or more.Now the technique has been extensively applind to the evaluation of Tertiary reservoirs with success.
