Abstract: The deep strata are the important targets of hydrocarbon exploration,and the key is how to correctly identify the profitable reservoirs in Shengli petroleum province.This paper,based on many more analytical data,describes the petrophysical properties,pore types and pore textures of deep reservoirs,and divides three types of reservoirs,such as low-permeability,medium-permeability,and tight reservoirs,of which the low-permeability reservoirs are widely spread,and the medium-permeability reservoirs are huge oil-gas potential.The pore types of deep reservoirs are dominated by micropores and intragranular pores.With increasing buried depth,the pore types transform intergranular into micro-and intragranular pores.The intergranular pores are mainly developed in quartz arenites and arkoses,fissures and fractures mainly exist in lithic arenites.The buried depth and lithology of deep reservoirs are the main factors to affect the evolution of pore types,as result in the differences of reservoirs properties in various regions.
