摘要： 通过对准噶尔盆地腹部陆西地区石炭系火山岩的研究发现，火山岩的储集空间有原生和次生的孔隙及裂缝组成，它们具有不同的组合类型。火山岩储集层的孔隙演化可以划分为5 个阶段：火山岩的形成阶段、风化剥蚀淋滤阶段、埋藏构造作用阶段、溶蚀改造作用阶段和油气聚集成藏阶段；同时，提出了对火山岩的储集空间影响较大的5种成岩后生作用：构造破裂作用、风化淋滤作用、蚀变作用、溶蚀作用、充填与胶结作用。

关键词: 准噶尔盆地, 石炭系, 火山岩, 孔隙, 储集空间

Abstract: The volcanic reservoir of Luxi area in hinterland of Junggar basin is made up of primary pores, secondary pores and fractures with different combinations. The evolution of the volcanic reservoir spaces has five stages: the formation stage, the efflorescence and denudation stage, the embedding and tectonic movement stage, the dissolution and modification stage and the oil-gas accumulation stage. In addition, five diagenesis factors influencing the volcanic reservoir spaces are presented, including tectonic breaking, efflorescence and eluviation, corrolding, dissolution, fill and cementation.

Key words: Junggar basin, Carboniferous, volcanic rock, porosity, pore, reservoir space
