塔河油田托浦台地区泥盆系东河塘组储层特征分析

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

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。

based on the 3D scismic 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.
