摘要
松辽盆地南部深层火山岩气藏具有储量规模大、丰度高、单井产量高的特点,是目前天然气勘探开发的主要领域。文章重点针对长岭断陷地区,结合岩芯分析资料,利用ECS元素俘获测井和FMI成像测井等先进技术进行火山岩岩性识别。在此基础上参照FMI成像特征,认为长岭断陷主要发育爆发相和溢流相,同时将其划分为6个亚相,并分别描述了各亚相的形成环境和岩石组合特征。
The volcanic rock gas reservoir in the south of Songliao basin has several traits such as bigger reserve, higher abundance and higher per well production, it is the main area for exploring and developing natural gas resource. Aiming at the Changling rift opening area, this paper uses ECS element to log technique and FMI image logging technique to identify the volcanic rock lithology combining on the core analysis data. Based on those techniques and confering FMI image characters, the conclusion is that the explosive facies and effusive facies is developed more than others facies of CHANGLING rift, they are divided into 6 subfacies, and the formation environment and combination character of each subfacies are described.
