Analysis on features and formation of igneous reservoirs

Igneous reservoir has become the focus of petroleum exploration. As compared with conventional petroleum reservoirs, it has its own characteristics. In combination with a variety of igneous reservoirs have been found in the country, the lithology and features of the common igneous reservoirs are analyzed, and the controlling factors for the forming of igneous reservoirs are discussed. The property of igneous reservoirs is concerned with lithology and lithofacies. The effusion of volatile matter, denudation, condensing and contraction and dissolution in the diagenesis, the tectonic movement and the subaerial eruption environment can improve the properties of igneous reservoirs.
