Abstract：Volcanic oil and gas reservoir prediction is one of the hotspots of the seismic reservoir prediction research.It is the key and foundation to research the petrophysical properties of volcanic reservoir for using seismic reservoir prediction successfully.Based on well logging interpretation results and core experimental data and logging data from eleven wells in the block of SS2-1 well in Songliao basin,it is studied in detail for seismic properties of volcanic reservoir in the third member of Yingcheng Formation.The results show that volcanic rock body can be recognized by using the difference of seismic reflection characteristics,but it is very difficult and uncertain to distinguish different volcanic rock.Because compressional wave impedance and density have good statistical regression relationship with porosity for the volcanic reservoirs,it is feasible to predict porosity using seismic data,but it is difficult to predict permeability.The elastic properties of gas,water and dry reservoir have marked differences,so it is feasible to distinguish the gas or water reservoir and the dry layer,but to estimate accurately gas saturation is very difficult.
