大港油田埕海地区作为一个典型的砂岩油藏,具有边底水的能量较大,油层厚度较薄的特点。为了保障油田的稳产高产,文章在研究了埕海地区砂岩油藏开发技术难点的基础上,试论述了油藏开发方案的优化,并总结了埕海地区砂岩油层水平井开发的新技术以及新工艺,为油田下一步水平井开发的方案部署提供了理论依据及现实参考。
As a typical sandstone reservoir, Dagang Oilfield in Huanghai area has the characteristics of large edge-bottom water energy and thin reservoir thickness. In order to ensure stable and high-yielding oilfields, based on the study of technical difficulties in the development of sandstone reservoirs in Yonghai area, this paper discusses the optimization of reservoir development plans and summarizes the new technologies for horizontal well development in sandstone reservoirs in the Yonghai area, It provides a theoretical basis and realistic reference for the scheme deployment of horizontal well development in the next oilfield.
