摘 要：Glutenite(coarse-grained clastic)reservoirs of intergranularesecondary dissolution pore type are dominated by residual intergranular pores and secondary dissolution pores,and characterized by low porosity,low permeability,strong heterogeneity,and highly variable physical *** is difficult to conduct a quantitative quality assessment of these reservoirs while their primary control factors remain *** this paper,experimental core data and drilling,logging and seismic data are used to assess the effect of sedimentary facies on reservoir *** sedimentary facies zones are identified by analyzing the characteristics of glutenite reservoirs,which includes investigating rock components and their effects on reservoir *** matrix content and rigid particle content are identified as the primary control factors for these *** curves sensitive to reservoir quality are selected and examined to continuously characterize the physical parameters of the *** establishes a calculation model of reservoir assessment parameters through multivariate regression and determines the quantitative assessment parameter *** quality of the glutenite reservoirs is defined using conventional logging *** study also predicts the plane distribution of high-quality reservoirs through geostatistical inversion of the reservoir assessment parameters based on conventional wave impedance inversion,thus providing insight and guidance for quantitative assessment and quality prediction of glutenite reservoirs of the intergranular-secondary dissolution pore *** application of this method to well deployment based on qualitative evaluation of the glutenite reservoirs in oilfields yielded favorable results.
