Diagenesis and porosity evolution of deep volcanic reservoirs in Songliao Basin
Online published: 2008-12-15
Based on core description, thin section analysis, pore character and microphotograph, the diagenesis and pore evolution of deep volcanic reservoirs in Songliao Basin are studied. It is believed that the rock types are mainly basalt, andesite, rhyolite, tuff and volcanic breccia. The reservoir spaces include primary pore, primary fracture, secondary pore and secondary fracture. The diagenesis and the pore evolution could be divided into two stages (eruption stage and post-eruption stage) which include condensation phase, thermogenesis phase, hypergenesis phase and burial diagenesis phase. The reservoir spaces are affected by the diagenesis events including metasomatism, faulting, pressure solution, deep denudation and hydrocarbon aggregation.
