Abstract: With the exploration and development practice of tight sandstone gas, the traditional geological understanding exposed many limitations and is inconsistent with practical data. Based on practical data from the exploration and development and experimental data from nuclear magnetic resonance, gas phase permeation analysis, isothermal adsorption experiment and gas reservoir paleo-pressure recovery of tight sandstone gas reservoirs in Ordos Basin, the knowledge of the geological characteristics of tight sandstone gas was supplemented and improved. we get some new geological understandings of tight sandstone gas：(1)the tight sandstone gas field composes of multiple pressure systems reservoir, which determines the need of dense well pattern rather than that of conventional gas reservoir dilute well wide agent and dilute well development;(2)the change of water saturation in tight sandstone reservoirs is great, and there also exists the phenomenon of super low water saturation, which is easy to form water block damage, so it demands to do best in reservoir damage protection;(3)water production is serious in the late development stage of tight sandstone gas reservoirs, so how to control the water production is the key problem in the phase of gas development;(4)there is a certain amount of adsorbed gas in tight sandstone gas reservoirs, which is important for the description of tight sandstone gas reservoir characteristics and seepage law, the prediction of single well productivity, the precise calculation of tight sandstone gas resource and reserves evaluation.

Key words: tight sandstone gas, geologic characteristics, water saturation, pressure system, adsorbed gas, Sulige Gasfield, Ordos Basin
