摘　　要：火山岩气藏具有岩石类型多、岩性复杂、岩性岩相变化快、厚度变化大、非均质性强等特点,该类气藏的渗流机理比较复杂。为了更深入的了解火山岩气藏的渗流特性,以松南气田火山岩气藏岩心为目标,建立储层的物理模型,基于单相渗流理论,采用实验分析的方法,通过单相气体非线性渗流实验,得出了不同渗透率的火山岩气藏在不同孔隙压力下的滑脱效应大小,以此解释火山岩气藏的渗流机理,为火山岩气藏的产能预测、产量递减规律、可采储量的评价、气井合理配产等提供理论依据。Volcanic rock gas pool have many kinds of rock types with complex lithology, large thickness variation and strong heterogeneity the percolation mechanism is complicated. In order to analyze the seepage characteristics of volcanic rock gas, taking the Songnan gas fi led core as target establishing reservoir physical models which based on theory of single seepage through the single-phase gas nonlinear flow experiments, to study the volcanic gas reservoirs with the different permeability the slippage effect size at different pore pressure, to explaining the mechanism seepage of volcanic gas reservoir, to providing a theoretical basis of the volcanic gas reservoir production forecasts, production decline, evaluation of recoverable reserves and gas reasonable proportion.
