【摘要】 松辽盆地北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。但由于火山岩气藏非常复杂,对火山岩气藏储层的描述一直是制约深层天然气勘探开发的瓶颈技术。通过对大量盆地周边火山岩的实地野外调查与深层气井取心资料的对比分析,综合运用岩石学、矿物学、测井和地震地层学等多学科联合攻关,初步形成了一套适用的火山岩气藏储层描述方法,根据这套火山岩气藏描述技术部署井位10口,实际结果火山岩钻遇率100%,预测的火山岩储层厚度相对误差小于20%,取得了很好效果。更多还原

【Abstract】 Volcanic gas reservoirs have been explored and developed for many years, and is paid considerable attention as a type of hydrocarbon reservoir. Deep volcanic gas reservoir in northern SongliaoBasin has the features of large-scale reserves, high abundance and high single well production, which is a main field of gas exploration and development. However, volcanic gas reservoirs have complex geologic features, so the description of them is a bottleneck technique of the exploration and development of deep gas reservoirs. Through a lot of researches, methods to describe volcanic gas reservoirs are developed.更多还原
