| 摘 要： | 长岭断陷营城组火山岩是该区增储上产的重要领域。通过对火山岩储层物性、孔隙结构、渗流特性等方面的分析研究,认为该区火岩山储层基本上属于低孔低渗—特低孔渗储层,火山岩气藏范围内以裂缝渗流为主;火山岩岩性、岩相及成岩后生作用是影响其物性好坏的主要因素。在成岩后生作用阶段形成各种次生孔隙和裂缝,对储集空间的形成改造以及储集性能的改善起关键作用。

| Abstract: | Volcanic rock of the Yingcheng Formation in the Changling Fault Depression has made great contribution to increase reserve and production.Based on analyses of physical property,pore structure and seepage characteristics of volcanic rock reservoir,it has been concluded that volcanic rock reservoir in the region has low and extra-low porosity and permeability.Fracture seepage dominates in gas re-servoir.Lithologic property,lithofacies and epigenesis effect of volcanic rock are the main controlling factors for physical property.Secondary pores and fractures generated during epigenesist,and were the key factors for reservoir deformation and improvement. |
