Abstract: Trachyte reservoir prediction technique has been successfully applied in Oulituozi and Huangshatuo oilfield, especially Huangshatuo oilfield has been built with reserves of ten millinos of tons , the process of special oil-gas bearin greservoir exploration has been driven in whole Liaohe oilfield Oulituozi and Huangshatuo oilfield are located in north central Dongbu depression of Liaohe basin , and the most important oil-gas bearing reservoir is trachyte reservoir .This paper studies drilling, logging , logging intepretation,oil production testing and the seismic data , applies the seismic attribute and the seismic inversion , forecasts the thickness, distribution and fracture of trachyte reservoir . The study indicates that the reservoir is fractured reservoir, it is well-developed and favorable for oil and gas accumulation inthe area . The result of this study may guides the following exploration in this area.
