Abstract: The Bashijiqike formation in the Keshen area of the Kuqa depression in the Tarim basin has an average burial depth of more than 6 000 m, which belongs to deep-burial low-porosity and ultra-low permeability sandstone reservoirs. The variations of the reservoir lithologies have significant influences on logging responses and reservoir physical properties such as porosity and permeability. The elemental capture spectrum logging and micro-resistivity imaging logging are used to accurately characterize lithologies, and the logging evaluation parameters that can reflect mineral compositions and rock particle distribution are selected, and according to particle sizes the models for porosity and permeability calculation in the Keshen area are established to improve the accuracy of reservoir physical property evaluation. The logging parameters that can characterize the petrological characteristics of the reservoir are extracted by introducing the concept of lithology-lithofacies. Based on the data of elemental capture spectrum logging and imaging logging and the comprehensive consideration of lithology, grain size and sedimentary structure, a reservoir lithology-lithofacies division standard is established for the Bashijiqike formation in the Keshen area. The application of the method in the reservoir evaluation in the Keshen area has gained good results, which could provide references for the evaluation of low-porosity, low-permeability reservoirs with large lithology variations
