摘要
Currently,there are many problems in the carboniferous reservoir at the ninth block,resulting in poor results of the exploitation and some wells without replacement layer.To address these issues,using core,thin section,scanning electron microscopy and other means,from volcanic lithology,lithofacies characteristics,pore characteristics,reservoir physical properties,the reservoir characteristics of Carboniferous volcanic reservoirs in the ninth block of northwestern Junggar Basin are researched and the reservoir spaces type is analyzed,so are physical properties and the controlling factors of reservoir propreties.The results show that:the main volcanic reservoir of this area is volcanic lava,clastic rocks and metamorphic rocks;pore types are mainly secondary porosity.
