Abstract：In order to look for alternative energy instead of conventional oil and natural gas， increase geological reserve of oil and gas resources in Ordos Basin and promote domestic unconventional oil and gas resources exploration and development， based on theories and practices in current domestic and foreign shale gas exploration and development， analyzed are various reservoiring geological and geochemical elements such as Mesozoic Yanchang Formation Long Seven layer’s sedimentary and tectonic movement conditions， distribution range， thickness， burial depth， type， abundance and maturation of organic matter and hydrocarbon-generating intensity. It can be concluded from the analysis that the sedimentary environment is fit for hydrocarbon source rocks， tectonic movement is also good for shale gas reservoir formation and shale layer has wide range， thickness strata distribution and moderate burial depth， organic matter is abundant and its maturity is high and its hydrocarbon-generating intensity is high. The study results suggest that geological conditions of Ordos Basin’s Mesozoic Long Seven layer’s shale formation are favorable. In the south of the basin， Wuqi-Yongning-Xiasiwan-Zhiluo is an area for especially favorable shale gas exploration and development.
