松辽盆地杏山-莺山地区火山岩储集空间类型特征及其控制因素

杏山－莺山地区火山岩地层中相继发现火山岩气藏，使深层火山岩成为松辽盆地的一个油气勘探新领域。通过运用火山岩岩石薄片、铸体薄片、扫描电镜以及压汞分析等多种分析测试手段，系统地研究了火山岩的储集空间类型及其特征，并分析其控制因素，认为研究区储集空间主要由宏观缝洞系统和基块孔缝系统共同组成。其控制因素主要考虑三个方面：火山喷发作用、构造运动作用以及成岩－表生作用。本研究对松辽盆地深层油气勘探油气勘探具有重要的指导意义。

Characteristics and controlling factors of volcanic reservoir spaces in Xingshan-Yingshan area of Songliao basin

Volcanic gas reservoirs have been discovered successively in Xingshan-Yingshan area thus making deep vol-canics become a new play of hydrocarbon exploration in Songliao Basin. Testing methods, such as thin section, casted thin section, scanning electron microscope and mercury injection, are used to study the types and characteristics of volcanic reservoir spaces, and to analyze controlling factors. It is thought that, within this study area, reservoir spaces consist of macro fissure-cave system and block pore-fissure system. The controlling factors mainly involve volcanic eruption , tectonic movement, and diagenesis and hypergenesis. This has very important significance for oil and gas exploration in deep Songliao Basin.
