【摘要】 利用文安斜坡的大量勘探资料,通过钻井、测井和三维地震资料的综合研究,确定了文安斜坡火山岩的地震反射特征。建立了火山岩的测井曲线组合特征。建立了火山岩测井-地震综合识别模式。精确刻画了沙三段和沙二段残余火山岩的分布范围。在此基础上,提出文安斜坡在沙河街组广泛发育火山岩,并且具有随时间推移火山岩分布空间向文安斜坡北部迁移的特征。该研究分析了沙河街组火山岩的展布情况,对沙河街组沉积相和油气分布情况的进一步研究具有重要意义。更多还原

【Abstract】 Seismic reflection characteristics of Shahejie Formation volcanic rocks in the Wen’an slope were summarized and illustrated by using large number of exploration date from Wen’an slope,and then logging characteristics and logging-seismic integrated model were established.Meticulous characterization of Es2 and Es3 volcanic: rocks’ spatial distribution was achieved through comprehensive study of drilling,logging and 3D seismic date.The Shahejie Formation volcanic rocks were developed largely in Wen’an slope,and the volcanic rocks’ spatial distribution migrates to the northern.This study lays foundation for further understanding of sedimentary facies and hydrocarbon distribution of Shahejie Formation in Wen’an slope.更多还原
