Low permeability tight gas reservoirs and condensate gas reservoirs account for a rather high proportion of domestic gas reserves,but many of them have low productivity.So it is significant to develop these reservoirs effi-ciently for continuous and stable development of China’s petroleum industry.Around the problems of the development of deep low permeability tight gas reservoirs and condensate gas reservoirs,this paper makes an analysis on the geo-logic and development characteristics of these reservoirs and presents ten proper technologies.Finally,five technical measures for the development of such gas reservoirs are proposed in detail.These are deep fracturing technology,treatment technology of accumulated liquids in condensate gas well and near well bore,gas injection technology when the formation pressure is lower than the maximum condensate pressure,phase behavior analysis technology in porous media of low permeability tight condensate gas reservoir and other gas reservoir engineering technologies.
