摘要
松辽盆地北部徐家围子断陷区深层火山岩和砾岩储层气藏具有非常好的勘探前景。本文基于徐家围连片三维地震资料,通过分析沉积相特征,地震属性特征,同时结合徐家围子丰富的钻井、地震资料和勘探研究成果,对沙河子组地层、营城组四段地层、登娄库组地层和泉一二段地层的烃源岩发育特征进行预测,同时通过分析火山岩或砂岩气藏的分布规律,总结了烃源岩分布对气藏分布的控制作用,为下一步寻找有利探区和井位部署提供了依据。
Deep volcanic rocks and conglomerate reservoir of Xujiaweizi fault depression of the northern Songliao basin have a very good exploration prospects.This article is based Xujiaweizi contiguous 3D seismic data,predicted the hydrocarbon source rock development feature of Shahezi formation,the fourth member of Yingcheng formation,Denglouku formation and the first and second member of Quantou formation by analyzing sedimentary facies and seismic attibute,and combined with the rich Xujiaweizi drilling,seismic data and exploration of research results.At the same time summarized the distribution of hydrocarbon source rock control effect of the distribution of gas reservoirs by analyzing volcanic rocks,or the distribution of sandstone gas reservoir,to find a favorable exploration area for the next step and provide a basis for well placement.
