欢北杜家台低渗透油层精细油藏描述研究

Fine reservoir description study on low permeability reservoirs in Dujiatai of Huanbei

为进一步提高欢北杜家台油层开发效果,开展了油藏精细描述研究,对欢北杜家台油层60个四级断块进行了分类评价和潜力分析,对全区目的层段地层、构造、沉积微相、油层分布特征及开发效果进行了分析评价,优选潜力断块区,多学科、多技术相结合进行油藏地质建模、数值模拟及剩余油分布研究。提出了改善油藏开发效果的对策,对同类油藏精细油藏描述研究具有一定的借鉴意义。

In order to improve reservoir development response in Dujiatai of Huanbei, fine reservoir description study has been conducted. 60 fault blocks of the fourth stage in Dujiatai, Huanbei have been classified, evaluated and analyzed for potential. The formation, structure, sedimentary microfacies, reservoir distribution and development response of target intervals in the area are analyzed and evaluated. Optimum fault blocks are selected for geological modeling, numerical simulation and residual oil distribution study by using multidiscipline and multi-technique. The measures for improving development response are proposed. This study is a reference for similar reservoir description study.
