摘要
通过对德惠断陷沙河子组泥岩盖层的单井数据统计分析,得出沙河子组泥岩宏观发育特征;对德惠断陷沙河子组泥岩取样,进行岩心数据分析,得出沙河子组微观封闭的相关数据进行分析。对沙河子组泥岩盖层进行参数划分以及对各指标赋予不同的权值的方法,对德惠断陷沙河子组泥岩盖层进行评价。
Through statistical analysis of individual well data of mudstone cap rock in Shahezi formation of Dehui depression,macro development characteristics of mudstone in Shahezi formation were obtained;Through sampling and core analysis,micro correlative data of Shahezi formation were obtained; Through dividing mudstone caprock parameters in Shahezi formation and giving different weights to each index, comprehensive evaluation of mudstone cap rock in Shahezi formation of Dehui depression was carried out.
