塔河油田托浦台地区泥盆系东河塘组储层特征分析

本文以托浦台三维地震资料解释为基础,根据工区的地质、钻井、测井等资料,分析了泥盆系D3d地层的地震响应特征;描述了储层的岩性特征和物性特征;对储层圈闭进行了评价,分析认为泥盆系以微幅构造圈闭为主,兼有构造——岩性复合圈闭;预测了该储层的有利储集相带,研究结果表明:泥盆系东河塘组主要有利储层发育在研究区的中西部、东南部,而工区的北部、中南部储集性较差,不利于油气的聚集。

Analysis of reservoir characterization in Devonian Donghetang Formation, Tuoputai district, Tahe Oil Field

based on the 3D seismic data of Tuoputai,by using geology,drilling and logging data of the work area,the seismic response of Devonian D3d is analyzed;the lithologic character and physical property are described;the reservoir trap is evaluated,with result is that low amplitude structural traps are main,tectonic-lithologic traps are also present;good belt is predicted in the reservoir,with the research indicating that good reservoir develops middle-west and southeast of work area,the northern and middle-southern is bad,then it is useless for accumulation of oil and gas.
