准噶尔盆地七中东区白碱滩组油藏单砂体刻画

摘要
精细单砂体刻画是在小层精细化对比的结果下,并在前人认识的基础上,以现代曲流河的沉积模式为参考,以砂体厚度等值线图为依托,落实单砂层,分析单砂层分布,并完成曲流河单砂体的精细刻画;研究同期与不同期单砂层间的叠置关系,为分析单砂层连通性奠定基础。在现有的认识基础上,与动态上充分结合,不断地修正上述认识,达到动静统一。
The fine single sand body characterization is based on the results of the fine contrast of small layers, including the previous knowledge, the sedimentary model of the modern meandering river and the contour map of the thickness of sand body. We have made an analysis of the distribution of single sand layer in completing the fine characterization of the meandering river sand body to study the overlapping relationship between the sand layer and the sand body in different periods. In the same period, we will try to lay the foundation for the analysis of single sand layer connectivity. On the basis of the existing understanding, it is fully integrated with the dynamics. The above-mentioned understanding is constantly revised to achieve the association of activity and inertia.
