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 4 1个韵律层。在此基础上 ,利用研究区内的 10 0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 Shangnan fault block is located in Dongying depression Shangdian Oilfield southwest. In this paper, the Dongying Formation in this area was studied by fine sequence stratigraphy. The top and bottom of Dongying Formation are all unconformities or inter-depositional sections, and Dongying Formation is a complete sedimentary sequence. In Dongying, the area developed a better lacustrine delta deposition. According to the lithology, sedimentary cycles and existing conditions of the sequence, three lowstands, lakes and highstands, nine quasi-sequences and 41 rhythm layers are defined. On the basis of this, based on the comparison of more than 10 drilling data and related seismic data in the study area and through the comparison of 14 sequence stratigraphic profiles, we have established fine, flow unit-level, sequence stratigraphy The three-dimensional space frame provides reliable data for oilfield production and has been well verified and has achieved certain economic benefits
