Many nature gas reservoirs are proved up in the Mesozoic of Ordosbasin, whether the gas reservoirs of Mesozoic different from the gas reservoirs of Paleozoic on the forming cause, need discuss very detailedly. In the paper,the forming cause are gained by the analysis of carbonate and oxygen isotope, the associated gases of oil field are named, the forming causes are different from Paleozoic. Due to the difference of tectonic intension, the forming causes aredifferent in different tectonic zones. Due to tectonic stabilization, the type of the forming cause is the associated gases of oil field on the slope of ShanBei. Due to tectonic intension, the type of the forming cause is the mixed gases on the fault zones of the wester.
Key words: Ordos basin; Mesozoic; Isotope; Gases of oil field; Mixed gases.
