Abstract: Low permeability tight gas reservoirs and condensate gas reservoirs account for a rather high proportion of domestic gas re-serves, but many of them have low productivity. So it is significant to develop these reservoirs efficiently for continuous and stabledevelopment of China's petroleum industry. Around the problems of the development of deep low permeability tight gas reservoirs andcondensate gas reservoirs,this paper makes an analysis on the geologic and development characteristics of these reservoirs and pre-sents 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 in-jection technology when the formation pressure is lower than the maximum condensatepressure, phase behavior analysis technologyn porous media of low permeability tight condensate gas reservoir and other gas reservoir engineering technologies.
