摘要

近年来,火山岩储层的研究已经成为油气勘探的一个新领域。由于火山岩的岩性差异较大,成因复杂,岩性分类方法也较多,这些都给火山岩的储层预测工作带来了困难。从测井及地质资料入手,分析了克81井区二叠系风城组火山岩的物性,然后在地震剖面上进行横向展布追踪,最后根据地震属性分析,成功识别了该井区的风城组火山岩圈闭。研究结果表明,克81井风城组火山岩具备形成有利圈闭的条件;提取的沿层总绝对值振幅属性和沿层波形分类(6类)属性验证了在地震剖面上追踪确定的克81井区风城组火山岩圈闭的可靠性。
In recent years,the studies of volcanic reservoirs have become a new field of hydrocarbon exploration.It makes reservoir prediction difficult that lithology of the volcanics are quite different,genesis is complex and its lithology classifications are not the same.This paper firstly analyzes volcanic rocks of Wellblock Ke 81 well in the Permian Fengcheng Formation by its well logs and geological data.Secondly horizontal distribution is confined through the seismic profile.Finally volcanic trap of Wellblock Ke 81 is identified successfully by seismic attribute analysis.The results show that there are favorable conditions for volcanic trap formation of Wellblock Ke 81 well,and total absolute value and waveform assortment(6 class) along layer show that volcanic trap of Wellblock Ke 81 is reliable.
