Abstract:

Igneous rock reservoirs are characterized by their extensive distribution, long geologic time and no exclusiveness of rock types. The primary pores, such as intercrystal pores and shrinkage pores, formed while igneous rocks cool down are not influenced by compaction. These characteristics, being different with that of sedimentary reservoirs, are very favorable for seeking deep oil and gas accumulations. In view of the problems concerning the characteristics, formation and evolution mechanism, time space distribution and prediction of igneous rock reservoirs, it is proposed that igneous petrology, volcanic geology, thermodynamics, physical properties of magma and hydrodynamics, as well as geophysics should be strengthened in study of igneous rock reservoirs.

Key words: igneous rock reservoirs, igneous petrology, volcanic geology, thermodynamics, hydrodynamics of magma, geophysics
