Geophysical Exploration Technology of Complex Volcanic Rock Gas Reservoir

Lithology identification of complex volcanic rock, reservoir prediction with seismic data and identification of<br>volcanic rock lithology and prediction of fluid property in reservoirs using wireline logging are key techniques for<br>volcanic gas reservoir exploration. Up to now, many exploration wells and a large amount of 3D seismic are<br>performed in volcanic gas reservoirs. Practice and theoretical research has establish a series of effective methods<br>of lithology identification and reservoir and fluid prediction by seismic and wireline logging, with much<br>achievement in gas field exploration evaluation and gas reservoir characterization of Xushen Gas Field.
