| 摘 要： | 尚南断块位于东营凹陷尚店油田西南部。本文对该区的东营组进行了精细层序地层学研究。东营组顶底均为不整合面或沉积间断面，东营组为一个完整的沉积层序。在东营期，该区发育了较好的湖侵三角洲相沉积。根据该层序的岩性、沉积旋回特征及现存状况，划分出了低位、湖进及高位3个体系域、9个准层序及41个韵律层。在此基础上，利用研究区内的100余口钻井资料及有关的地震资料，通过14条层序地层学剖面的对比，建立了研究区内的精细的、流动单元级别的、层序地层立体空间格架，为油田生产提供了可靠的资料，并已得到很好的验证，取得了一定的经济效益。

| Abstract: | The south Shangdian fault block is located in the Shangdian region of Shandong Province. The sequence stratigraphy of the Dongying Formation in this block has been thoroughly studied. The Dongying Formation is well defined by unconformity surface or discontinuity surface both at its top and bottom, hence it is believed to be a well developed sequence. Within this Formation, some superb retrograded lacustrine delta deposits have been developed due to lacustrine transgression. According to analyses of lithology, cyclicity, and the preservation state of the Dongying Formation, three systems tracts, lowstand, transgressive, and highstand, have been differentiated and a total of 9 parasequences and 32 rhymes are further subdivided. In addition, more than 100 boreholes and related seismic profiles have been studied, sequence stratigraphic correlations along 14 cross sections have been made, and finally the precise, flow unit grade, and stereoscopic sequence stratigraphic framework of the Dongying Formation has been reconstructed in the south Shangdian fault block. As a result of this analysis, a set of scientific data is provided for production of the oilfield, some benefits have been gained and the method has been proved to be efficient. |
