摘要： 准噶尔盆地腹部火成岩分布广泛,火成岩油气藏裂缝发育,产量高,为新疆油田增储上产发挥了重要的作用。从化学成分、产状和结构、矿物成分等方面,对准噶尔盆地腹部火成岩进行了分类及特征分析,认为准噶尔盆地腹部火成岩岩性种类比较齐全,既有喷出岩又有侵入岩和火山碎屑岩,在化学成分上从基性到酸性均有分布,部分岩石蚀变严重。这些认识有助于指导该区火成岩油气藏的勘探与开发。

Abstract: The igneous rocks in Junggar basin are in wide distribution. The igneous reservoirs are characterized by developed fractures and high yield. They play an important role in incremental reserves and production in Karamy field. This paper presents the classification and characteristic analysis of the igneous rocks in hinterland of Junggar basin in term of the chemical component, occurrence, texture and mineral composition of the rocks. It is recognized that there are relative complete types of igneous rocks composed of extrusive rock, intrusive rock and pyroclastic rock from basic to acidic ones in hinterland of Junggar basin, and part of them belongs to alteration ones. These recognitions could be helpful to proper knowledge of the potentials and to guidance of exploration and development of such reservoirs.

Key words: Junggar basin, hinterland, igneous rock, classification, characteristic, feature
