%X Ever since a long time ago,the oil-gas exploration home and aboard is mainly about marine facies carbonatite and sea and land facies clastic rock.Volcanic is always the forbidden area of exploration.In Yanshan Period,because of slant diving of pacific plate to Chinese continental plate,the rift basin in Songliao took place the back-arc stretch rift and causes the mass eruption of volcanic which is mainly eruption facies and overflowing facies.The quality of reservoir of volcanic is better and not strictly controlled by burial depth,but its anisotropy is obvious and porosity is 0.5%～18.7% and permeability is 0.0001×10-3～1×10-3μm2.The catching temperature of inclusion in calcite vein or quartz vein in crack of volcanic is 105～250℃,and majority is 120～160℃,and the 3He/4He specific value of gas in inclusion is 2.86×10-7～7.33×10-6 and the average number is 2.48×10-6.R/Ra=0.26～5.24,majority of R/Ra>1.40Ar/36Ar=293～2485 and the principle value interval is 500～900.4He/20Ne=0.32～1255,the principle value interval is 10～95 and 170～370.δ13C1=-17.1‰～-28.7‰,δ13C2=-23.4‰～-32.4‰,δ13Cco2=-10.97‰～-21.73‰.The data of He,Ar,C and other isotopes in inclusion reveal that there is mantle-genetic path,so there is mantle-genetic inorganic genetic gas in the volcanic.According to the attitude and distribution of volcanic and its relationship with rifting activity,inorganic genetic gas exists mainly around the rift vein and organic genetic gas or the mixture gas of inorganic genetic gas and organic genetic gas mainly exists far away from the rift vein.The research results of isotope in inclusion in this article have the significant reference value of confirming the genetic type and distribution of gas in the deep volcanic reservoir in Songliao basin and guiding the following exploration of natural gas.
