Study on Logging Evaluation Technique for Shale Gas Reservoirs ——By Taking Well S1 for Example

It was of great significance for guiding a systematical and precise evaluation of parameters of shale gas reservoirs in shale gas exploration and development.Therefore the application of well logging data continuity for the establishment of shale gas reservoir logging evaluation system was particularly important.The standard of qualitative identification of logging curve of shale-gas reservoirs was studied,models were established for quantitative interpretation of shale gas reservoir parameters in the area and some of the models were corrected through core analysis data,shale gas reservoir identification,total carbon contents,reservoir physical properties,gas content and geologic and well logging evaluation of rock brittleness in Well S1 were verified by using core analysis data.Actual results show that the shale gas well logging evaluation system can effectively assess the shale gas reservoir parameters,it can provide logging and technical support for shale gas exploration and development at the late stage in the region.
