松辽盆地长岭1号气田营城组火山岩岩相分析
|
摘要
松辽盆地长岭1号气田是吉林省迄今为止发现的规模最大的气田,其中70%以上的储量位于营城组火山岩储层中。针对困扰气田开发的岩性、岩相认识不清的问题,在充分利用岩心、测井、录井及地震资料的基础上,借助岩相标志识别、电测曲线分析、地震属性提取及波形分类等技术手段,建立了火山岩岩相模式并进行了测井相及地震相划分,获得营城组3个火山喷发旋回的岩相平面图,整体认识了该气田火山岩岩相在纵向上及平面上的展布特征。通过分析不同岩相对应的储层物性特点,指明了该气田储层发育有利相带及有利部位,并对深层火山岩气藏的储层展布进行了探讨。
The Changling-1 field in the Songliao basin is the largest gas field discovered in Jilin province up to now, with 70% gas reserves distributed in the Yingcheng Formation volcanic reservoirs. The poor understandings of lithology and petrographic facies influence gas field development. Various techniques, such as petrographic mark recognition, log analysis, seismic attribute ABSTRACTion and waveform classification, were applied to establish petrographic models of the volcanic rocks and to identify electrofacies and seismic facies based on an integration of core, log and seismic data. The petrographic facies of three volcanic eruption cycles in the Yingcheng Formation are mapped, and the overall vertical and lateral distributions of the volcanic petrographic facies are recognized. Based on an analysis of the physical properties of the reservoirs corresponding to different petrographic facies, this paper present favorable facies belts and intervals for development of reservoirs and discusses the distribution of deep volcanic reservoirs in this gas field.
