Aimed at the existing fussiness and blunders in data processing of reservoir evaluation, the authors designed a software package in VBA language based on the intrinsic relationship between the parameters. Using deviation data, well data, layering data, sand body data, well logging interpretation data and interbed data, its function includes deviation correction, statistics of sand body thickness and sand-shale ratios, interbed data computation, interbed deduction and net computation, zoning statistics of reserve parameters, coordinate selection, and data format translation between common softwares.
