Application of Geophysical Prospecting Technologies to Volcanic Rock Identification and Reservoir Prediction———Examples from Songliao basin and Junggar basin

Abstract

Abstract: Volcanic rock is one of important petroliferous reservoir rocks. The reservoir space of volcanic reservoir has a certain correlation with volcanic lithofacies. The research of the measured data from outcrop and cores shows that there exist differences of the density, magnetic, electrical and some other petrophysical properties between volcanic rocks and surrounding sedimentary strata and among various lithologies of volcanic rocks. In this paper, the volcanic rock identification and reservoir prediction are mainly based on seismic data and combined with drilling, gravity-magnetic-electrical prospecting data. Such a method is applied to the research of Songliao basin and Junggar basin, and improved that it is simple, practical and effective for application, being one of the effective means for volcanic rock identification and reservoir prediction at present.

Key words: geophysical technology, volcanic identification, reservoir prediction
