摘要
Based on core observation,cast thin section,intrusive mercury curve,the reservoir characteristics have been studied and on this basis,by using multiwell comparison,the criterion of reservoir classification have been summarized.The result shows that the lithologies of the gravel-bearing sandstone Formation of carboniferous system in TZ gas field are mainly lithic sandstone and lithic silicarenite;the reservoir spaces mainly are primary interparticle pore and relatively more crevice can be seen in this area;the mainly texture of the reservoir pores are medium,miniature pore throat.The region of interest reservoir are mainly of typeⅡ and Ⅲ,belonging to lowporosity and lowpermeability reservoir and showing the characteristics of middle to worse reservoir.
