摘要
对迪那气田苏维依组采用"标准层对比,旋回对比,分级控制"的地层对比方法,开展储层精细划分对比研究工作.研究区苏维依组下伏和顶部的2个区域一级标准层以及内部4个二级标准层是划分气层组和砂层组的关键;3个三级旋回、5个四级旋回以及19个五级旋回的沉积特征是进行砂层组和小层划分对比的依据.根据以上标准层和旋回特征将迪那气田古近系苏维依气层组划分为5个砂层组和19个小层.
The stratigraphic correlation methods, which include marker bed correlation, cycle correlation and hierarchical control, are adopted to carry out fine division and correlation of the reservoir of Suweiyi Formation in Dina gasfield. Two primary marker beds at the top of and underlying the Suweiyi Formation and four internal secondary marker beds are key to divide gas layer group and sand group, while the sedimentary characteristics of three third-order cycles, five fourth-order cycles and 19 fifth-order cycles are the basis to divide sand group and sublayer. The Suweiyi Formation of Paleogene can be divided into 5 sand groups and 19 sublayers based on the characteristics of marker beds and sedimentary cycles above.
