white alkali soil

On the basis of studying phase markers of lithology, paleontology and logging facies, it is considered that Baixiantan Formation belongs to braid river delta-lacustrine sedimentary system in studied area, the braid river delta sediment is distributed over the T_3b~1 sand group of Triassic Baixiantan Formation, which is composed of shallow lake subfacies, semi-deep lake-deep lake subfacies.

在详细研究岩性、古生物和测井相等相标志的基础上,认为研究区白碱滩组属辫状河三角洲湖泊沉积体系。

The sedimentary environment of lower Karamay formation is alluvial fan,and reservoir heterogeneity is very strong in the central part of No 6 block of Baijiantan oilfield.

白碱滩油田六中区克下组为冲积扇沉积,储集层非均质性严重,在对这类储层进行综合评价时,除了用到孔隙度、渗透率和泥质含量等常规评价参数外,在这里增加了变异系数、突进系数和级差三个参数,使得非均质性的作用在储层综合分类评价中得到充分体现;然后应用聚类分析将储集层分为三种类型,其中Ⅰ类储层最好,Ⅱ类储层次之,Ⅲ类相对较差;最后对每个单层中三类储层的分布进行了分析,进而指导油田的进一步开发。
