摘　　要：为了研究和认识了解松辽盆地腰深地区火山岩的成岩作用及其对储集空间演化的影响,进一步指导火山岩气藏的下一步勘探与开发。在进行大量岩心描述的基础上,再结合室内岩石薄片镜下鉴定,铸体薄片孔隙特征分析,显微照相及扫描电镜观察对腰深地区营城组火山岩的成岩作用进行了详细地研究。结果表明:营城组共发育10种成岩作用类型,其中溶解作用、风化淋滤作用、构造作用对储层孔隙的形成起决定性作用;储集空间演化共有四个阶段,成岩作用对其储集空间演化的影响很大。In order to study and understand volcanic rock diagenesis and its effect on the evolution of reservoir space in Yaoshen area to further guidance exploration and development of volcanic gas reservoir, petrological characteristics and diagenesis of volcanic reservoirs of Yingcheng formation in Yaoshen block were studied based on core description, thin section analysis, pore characteristic analysis, microphotograph and scanning electric microscope observation. The results show that there are 10 kinds of diagenesis types in Yingcheng group, the solution effect, weathering leaching effect and structure effect have a decisive influence on reservoir pore formation; reservoir space evolution has four stages, the diagenesis has great influence on reservoir space evolution.
