摘要
在松辽盆地,火山岩储层已成为深层天然气勘探的重要储层类型。但是由于火山岩复杂多变,岩相识别难度大,往往给火山岩油气藏勘探和开发带来极大风险。本文通过对松辽盆地北部兴城地区火山岩储层的研究成果分析,利用由地震响应特征形成的火山岩相地震地质解释模式,并结合相关的钻井、测井及区域地质资料,将该区的火山岩相划分为爆发相、溢流相和火山沉积相三种亚相;用延拓法可视化技术,精细地刻画出火山口的地貌。此种识别方法为该区火山岩油气藏勘探开发提供了可靠资料。
In Songliao basin, the volcanite reservoir has become important reservoir type in deep natural gas exploration. But the volcanite is complex and variable, this makes the lithologic identification very difficult and brings very large risk in exploration and development of volcanite reservoir. Through analysis of studied results of volcanite reservoir in Xincheng area, northern part of Songliao basin, by using seismic-geologic interpretation mode of volcanite facies formed by characteristic seismic response and combining with relative drilling, logging and regional geologic data, the papers divided the volcanite facies into three subfacies: eruptive facies, overflow facies and volcanic depositional facies, and used continuation visualization technique to finely geomorphic description of volcanic crater. This identification approach can provide reliable data for exploration and development of vulcanite oil-gas reservoir in the region.
