Abstract：Conventional single-model machine learning methods used in tight-sand gas reservoir interpretation on well logging data have the multi-solution problem.To overcome this problem,we use the XGBoost algorithm.Based on logging data in the Area A,different types of well logging data are used as input variables,and a regression prediction model is established by XGBoost algorithm.The porosity and permeability in this area are predicted.The optimization of various parameters in XGBoost algorithm is also discussed.The classification prediction model established by XGBoost algorithm predicts reservoir types in the area.Based on our prediction results,the XGBoost algorithm achieves a better porosity & permeability prediction and tight-sand gas reservoir identification in the area compared with the random forest method and vector-supported machine algorithms.
