摘　　要：通过较系统的火山岩成藏条件研究 ,认为东部凹陷中段沙三段火山岩具有离油源近、储盖组合好、油气运移通道畅通、构造形成期与油气运移配置好等优势 ,有利于火山岩成藏。本区主要以沙三段火山岩成藏为主 ,火山岩成藏在本区主要有 4种模式 ,不同地区有不同的特点 ,只有结合不同地区的特点 。Igneous reservoir forming conditions of Sha3 formation, central east sag are studied systematically. Results demonstrate these area features short distance to oil source, good combination of oil reservoir and cap, smooth oil & gas migration channel, finely accommodated relationship between structures forming period and oil & gas migration, as are all favorable igneous reservoir forming conditions. In addition, 4 types of igneous reservoir formed within this area mainly are from Sha3 igneous rock. Only with exploration methods in accordance with specified areas will do and satisfactory results can be achieved.
