Abstract：Using 2D and 3D seismic data interpretation, we have conducted volcanic rock identification and favorable zone evaluation based on the geological structure, the sedimentary and tectonic history in Wangfu Fautt Depression. The observations are obtained as follows:① The main rift in NE has double fautt structure properties controlled by three main faults. It developed three structural belts: Shandongtun structure bett, Xiaochengzi structure bett, and Wujiatun structure bett. The tectonic evolution of Wangfu Fautt Depression can be divided into four stages：faulting period, fautt-to-depression transforming period, depression period, and withered period. Three gas-bearing series were developed：clastic rocks of Quantou Formation, vo--canic rocks of Shahezi Formation and Huoshiling Formation. The primary gas reservoir of Huoshi--ing Formation is the largest reserve among them. ② The volcanic reservoir of Huoshiling Formation is divided into top rhyolite reservoir and andesite reservoir. Seismic reflections of rhyulite are characterized by high frequency and continuously strong amplitude, but andesite reflection is weak and messy, and discontinuous. The main reservoir of Shahezi Formation is sedimentary volcanic breccia in the bottom, which appears as low-frequency continuously complex wave with middle energy on seismic sections.③ Our well location proposal focuses on the Xiaochengzi structural bett and the Shandongtun structural bett. Some important gas reservoirs are discovered by drilling.
