| Application of Integrated Exploration Based on Gravity, Magnetic, Magnetotelluric, Well, and Seismic Properties in the Identification of Deep Volcanic Rocks of Carboniferous in Dabasong Uplift |
| In recent years, the exploration of volcanic rocks of Carboniferous in Junggar basin repeatedly made breakthroughs, and volcanic reservoir shows a good prospect. Owing to restricting factors such as burial depth, exploration methods, and quality of geophysical data, the identification and characterization of deep volcanic rocks of Carboniferous in Junggar basin remains controversial, making seismic exploration difficult in oil field. Therefore, improving the resolution and identification of deep volcanic rocks using existing geophysical exploration methods is of great theoretical and practical significance. Moreover, they can be identified and defined using integrated geophysical exploration, owing to the density, magnetic, resistivity, or other physical properties of special geological bodies. After analyzing well and physical properties, the plane distribution of Carboniferous volcanic rocks in Dabasong uplift is predicted based on gravity, magnetic, and electronic anomaly, and the favorable target area for seismic exploration of deep volcanic rocks is confirmed. The deep volcanic rocks are quantitatively identified and predicted using seismic facies analysis, seismic attribute interpretation, structure mapping, and comprehensive evaluation. In this study, we summarize the high precision seismic data acquisition; the integrated application of gravity, magnetic, electric, and seismic methods; and the joint inversion of deep special geological bodies. This study improves the precision of exploration of deep volcanic rocks in Junggar basin. |
