Abstract：Due to its shield from seismic energy penetration, widely distributed volcanic rocks in Dayangshu Basin result in the deterioration of seismic data quality in underlying strata, which restricts the reservoir exploration. To solve this problem, we propose a comprehensive inversion of gravity and magnetic constrained by reliable shallow seismic interpretation combined with petrophysic and electric interpretations. Based on this inversion we obtain the basement distribution, the Jiufengshan - Longjiang group thickness in Dayangshu Basin, and also the favorable exploration zones. Finally we perform an effective comprehensive geophysical interpretation. According our comprehensive analysis, Yulintun Depression can be considered as one of the main oil and gas exploration targets.
