Multiparameter Logging Evaluation of Chang 73 Shale Oil in the Jiyuan Area, Ordos Basin

The accurate evaluation of shale oil and gas reservoirs is great significance to the integrated development geology engineering. Based on core analysis, conventional logging, array acoustic logging data, total organic carbon, hydrocarbon generation potential, brittleness, anisotropy were calculated. p-wave time difference curves calculated by artificial neural network (ANN) method curve fitting compared. multiresolution graph-based clustering (MRGC) was used classify into three categories evaluate classification results. Brittle minerals such as quartz feldspar mainly found be present in clay which consisted illite. Chang 73 reservoir rich matter has potential for survival. formula shear wave meter demonstrated high accuracy did not require a complex ANN model. MRGC can well types. results reduce interference human factors are more scientific reasonable. This research reservoirs.
