摘　　要：目前国内对火山岩成岩作用的研究基本停留在定性的静态研究阶段。与盆地埋藏热史-烃类充注史-构造演化史相应的火山岩储层的成岩-孔隙时空动态演化过程方面的研究依然缺乏。各类薄片显微镜下火山岩中原生矿物、次生矿物、孔隙类型等的精细研究与定量统计,利用图像孔喉分析、物性测试、X-射线衍射分析、扫描电镜观察、包裹体荧光、包裹体均一温度与激光拉曼探针成分分析等多种分析测试手段,对松辽盆地下白垩统营城组火山岩的成岩作用与成岩演化过程进行了深入研究,确立了火山岩的成岩-油气充注序列,划分了成岩作用阶段;结合松辽盆地埋藏热演化史、烃类充注史、构造演化史,建立了与埋藏热演化史-烃类充注史-构造演化史-地质时代相应的火山岩的成岩-孔隙时空动态演化过程与模式,在此基础上讨论了火山岩的成岩作用与成岩演化过程对火山岩储集性能影响的机理。Domestic research on volcanic reservoir diagenesis basically stays in a qualitative static research stage at present. The study of the dynamic process of temporal and spatial evolution of diagenesis and pores for vol- canic reservoirs corresponding to burial thermal history- hydrocarbon filling history- structural evolution is still a blank area. The study of the diagenesis and diagenetic evolution process were carried out thoroughly, the diagenetic-hydrocarhon filling sequence of volcanic rocks of the Yingcheng Formation in Songliao Basin was elucidated and the volcanic diagenetic stages were divided in this paper, based upon the observation and de- scription of drilled cores, the identification and quantitative statistics of primary and secondary minerals and pore types under microscope, the measurement of porosity and permeability, image pore throat of volcanic res ervoir rocks, X-ray diffraction analysis for clay minerals, observation under scanning electron microscope, and analysis of homogeneous temperature, chemical compositions and fluorescence of diagenetic liquid inclusions in volcanic rocks. The temporal and spatial dynamic evolution process of diagenesis and pores for volcanic reser- voir corresponding to burial thermal history - hydrocarbon filling history - geological age - structural evolution was established finally, and impact mechanism of diagenesis and diagenetic process on volcanic reservoir quality was discussed in the paper. This research is of great significance both in theory and practice for understanding the evolution of the volcanic reservoir quality during the geological evolution process of the basin including bur- ial - diagenetic - hydrocarbon accumulation- tectonic setting evolution with geological age, and impact parame- ters on volcanic reservoir quality, as well as for guiding hydrocarbon exploration and development and predic- ting prospect hydrocarbon reservoir areas.
